Seven reduced-scale prestressed concrete (PC) pile specimens for landing stages simulating four levels of corrosion were tested to investigate their structural cyclic lateral load-carrying behaviour. Three corroded specimens were repaired using fiber-reinforced polymer (FRP) jacketing before testing. In this paper, the force-based fibre element (FFE) and the OpenSees software are used to analyse the seven PC pile specimens, achieving good corroboration with tests. Because the corrosion in such piles is horizontally asymmetric, the validated FFE models are used to execute 78 pushover analyses along various lateral directions to determine the multi-directional lateral strengths of the six corroded specimens. Based on the FFE analyses and experimental observations, this study makes design recommendations for FRP jacketing for use in repairing corroded landing stage PC piles. The FFE modelling is also extended to simulate the entire pile-soil system of an in situ pile lateral load test, validating its feasibility and accuracy for an entire full-size pile-soil system. © 2013 © 2013 Taylor & Francis.

Corrosion and deterioration of concrete piles are common prob-lemsfor wharf structures. In Taiwan, corroded prestressed concrete (PC) piles supporting landing stage structures are frequently repaired and strengthened using carbon fiber-reinforced polymer (CFRP) jacketing. This paper presents an investigation on corroded and CFRP-repaired PC piles for landing stage structures. Seven reduced-scale PC pile specimens were tested to investigate their cyclic lateral load-carrying behavior. Four types of specimens were made to simulate four different levels of corrosion severity. Three corroded specimens were repaired using the CFRP jacketing prior to testing. The experimental results showed that the CFRP jacketing is rather efficient in terms of lateral strength, capacity for deformation and energy dissipation, and stiffness degradation, and is effective in repairing the seismic-resistance capacity of the corroded specimens. This study also conducted finite element (FE) analyses to analyze the tests of the seven specimens, achieving good corroboration between the analytical results and the tests. © 2012, American Concrete Institute.

The effectiveness of emergency medical service (EMS) depends on the existing physical infrastructure and the allocation of medical resources. EMS is a challenging task due to the spatial distribution of the population and the geographical layout in the urban region. The management of emergency medical units (EMUs) and hospitals should be assessed to provide an efficient service. The objective of this research effort is to assess the current EMS of New Taipei City using geospatial analyses such as facilities' service area. In this study, spatial statistics for EMUs and hospitals are conducted. In addition, regions that cannot be reached within 10 minutes under pre-assumed conditions by EMUs are discovered, and interpolation of the travel interval is conducted and investigated. The geospatial arrangement of EMUs, and the upgrade or new constructions of hospitals are suggested to strengthen the efficiency of the emergency medical response. Future work is directed towards more advanced and complex spatial and temporal analyses to better assess the city's medical infrastructure. © 2013 American Society of Civil Engineers.

This paper assesses the Taipei's fire rescue capability against post-earthquake fires (PEFs) from a hypothetical earthquake. Taiwan's Shanchiao Fault was used as the trigger fault for establishing earthquake modeling assumptions. Monte Carlo simulation was used with hypocenter coordinates, the Richter magnitude scale, and earthquake focal depths as the uncertainty analysis variables for performing stochastic simulations of 100 sets of seismic event parameters. These parameters were entered into the Simple Earthquake Seismic System (SESS) and the Taiwan Earthquake Loss Estimation System (TELES) to conduct uncertainty analysis regarding PEFs. PEFs were simulated and the disaster readiness of all firefighting squads (strongholds) in Taipei was investigated to analyze the uncertainty in PEF rescues. The SESS analysis results indicate that the original risk probability was 25.26%, increasing to 45.88% with the activation of a regional mutual aid system. The original risk calculated by the TELES was 52.97%, which increased to 96.22% of the overall disaster response capacity requirements after the regional mutual aid system was launched. Although the SESS results remained below the 60% risk threshold following the launch of the regional mutual aid system, the rescue capacity was substantially increased. The TELES analysis results indicate that the regional mutual aid system can substantially increase local disaster rescue capacity, nearly satisfying all disaster resource scheduling requirements. The location, scale, and pattern of earthquakes and the resulting casualties are always uncertain. However, the results of this study verify that the 2 independently developed earthquake damage estimation systems can provide an effective reference for post-earthquake rescue scheduling assessments. © 2014 World Scientific Publishing Company.

Wetlands | Year: 2011

We used non-metric multidimensional-scaling analysis (NMDS) to analyze the variation and associations of abiotic and biotic variables among and within three constructed wetlands in metropolitan Taipei. Abiotic variables included NH4-N, biochemical oxygen demand, total phosphorus, suspended solids, dissolved oxygen, water temperature, pH, and electrical conductivity and were sampled monthly from April to October 2007. Biotic variables included zooplankton and phytoplankton communities and were sampled in May and August 2007. We sampled front-compartment, mid-compartment, and effluent portions of each wetland. BOD, NH4-N, TP, DO, SS, and pH differed significantly (p<0.05) among the three wetlands. Phytoplankton communities in each wetland were unique. Zooplankton differed between the two wetlands (Hsin-Hai Bridge I and Fu-Zhou Bridge). Overall, the three wetlands supported unique abiotic and biotic communities. Zooplankton and phytoplankton communities were correlated to TP, NH4-N, DO, and pH levels. © Society of Wetland Scientists 2011.

With the widespread use of the Internet, adopting e-learning systems in courses has gradually become more and more important in universities in Taiwan. However, because of limitations of teachers' time, selecting suitable online IT tools has become very important. This study proposes an analytic hierarchy process (AHP)-multi-choice goal programming (MCGP) evaluation model as a decision aid to help decision makers obtain appropriate online IT tools considering the time limitations of teachers and students. To demonstrate the usefulness of the proposed method, this study implements the evaluation model in computer courses at a university in central Taiwan. For different purposes, teachers can set different time limitations and aspiration levels for each goal to rank the range of possible IT tools. With the AHP-MCGP evaluation model, teachers can find the most suitable time for the allocation of possible IT tools in the e-learning system to improve students' learning practice. © 2014, Baywood Publishing Co., Inc.

Christie’s rental staging partner Hexogon Solution Pte Ltd has ignited the Christmas spirit by delivering spectacular visuals that captivated thousands of spectators who turned up for the official lighting up ceremony of the highly-anticipated “Christmasland in New Taipei City” event on November 19. The stunning projection mapping performances, which runs nightly until January 2, 2017, are planned and executed by Hexogon Solution using a total of 42 Christie Boxer 4K30 3DLP® projectors. A slew of bright and vibrant visuals depicting Christmas adventures of the beloved Santa Bear and Fang Tou Bear family project onto the façade of the 30-storey New Taipei City Hall building in Banqiao District, as well as a fascinating 360-degree projection on a 36-meter-high cone-shaped Christmas tree in front of the building. Not only does this mark the debut of Boxer 4K30s for a major event in Taiwan, it is also the biggest ever projection mapping performance to be held here – with a projection area of 5,239 square meters (the size of a soccer field). Adrian Goh, Group Managing and Artistic Director, Hexogon Solution, said, “We are immensely honored to be given this opportunity to create this visual spectacular for the New Taipei City Government, by deploying 33 Boxer 4K30s for projections on the building’s surface and nine projectors for mapping around the cone-shaped Christmas tree. Our objective is to create a world-class performance for the enjoyment of Taiwanese spectators during this festive period. At the same time, we wish to set the standard of what it takes to deliver a good projection mapping show in terms of technology, brightness and image quality in Taiwan.” According to Goh, preparations for this event commenced in June with the design of projection mapping contents, which were created completely in-house by the Hexogon team. “For this performance, we worked towards achieving contents with a more three-dimensional approach. The specified characters were created in 3D, rather than using 2D animation that was done previously. The setting also involved a lot of optical illusion techniques, by conducting many rounds of simulations with mapping to bring the environment to life.” The Hexogon team worked round the clock to meet the short timelines and to overcome the unpredictable on-site weather conditions, as the nightly performances have to continue regardless of the weather. Tapping on the valuable experience gathered during its involvement in Singapore’s National Day Parades, the Singapore Formula 1 Grand Prix, as well as last year’s South East Asian sporting event, which set a new Guinness World Records title for the greatest light output in a projected image, the Hexogon team successfully overcame the challenges to complete the setup in a week's time. “We developed our own enclosures that allow alignment and even the actual show to run under extreme weather conditions. With proper exhaust, cooling system and optical glass front case specially customized for this event, we are able to extend the heat tolerance of the Boxer 4K30 projectors to better manage the performances,” said Goh. The result is a mesmerizing Christmas extravaganza that spread the holiday cheer and Christmas fun for both the young and old. Featuring a series of exciting events from county fairs and large concerts to markets selling handmade goods and carnival parades, the “Christmasland in New Taipei City” event is one of the most popular hangouts during the Christmas season, as it embodies a joyful and celebratory atmosphere. “We’re pleased with the performance of the Boxer 4K30s and are also delighted to accomplish our objective of delivering the biggest projection mapping performance in Taiwan. The client is also happy that whatever we suggested has all been fulfilled and proven correct. Hopefully this will set a new standard and customers’ expectation for future shows in Taiwan,” Goh said. Lin Yu, Vice President, Christie Asia Pacific, commented, “As one of the most prominent rental stagers in the region, Hexogon Solution is continually improving its capabilities and know-how to deliver spectacular and truly memorable visual experiences. I’m delighted that our Boxer 4K30 projectors has once again played an important role in the staging of the largest ever projection mapping performance in Taiwan. I congratulate Adrian and his team for delivering another fantastic show during this festive season, and look forward to more exciting projects from Hexogon Solution in the near future.” Weighing in at less than 160 pounds (68kg), Christie Boxer 4K30 is a 30,000 lumen, high-resolution, projector designed for high impact live events. Boasting 4K (4096 by 2160) native resolution and 3DLP® quality, and built-in Christie TruLife™ image processing to provide the highest bit depth and fastest frame rate, the Boxer is easy to use and offers optimum feed and performance flexibility.

Even though the design-build (DB) delivery method has become a popular construction project delivery method in many countries, it is relatively rare in Taiwan. This study investigates the problems and difficulties that Taiwanese owners may encounter during using DB delivery methods. Twenty six problems over the four key stages of the DB process were first identified based on previous studies and expert interviews. A questionnaire survey was then conducted to determine the most pressing problems for Taiwan. The results of statistical analyses show that Taiwanese owners face key problems at all stages of the DB delivery method, especially during the tender preparation and valuation stages. These findings can be used by Taiwanese owners for successfully executing DB projects. © (2013) Trans Tech Publications, Switzerland.

A building on fire is a smoky and dark environment both for firefighters and for civilians trapped inside. The faster firefighters find a way to search for and rescue civilians at a fire scene, the higher the survival rate of those trapped inside. This study presents a discussion on the characteristics of firefighter wayfinding under low visibility. The firefighters who participated in this study underwent testing at a training ground. The participants’ search and wayfinding paths were recorded using radiofrequency identification (RFID) technology. The results revealed that the mean searching time in each room decreased from 135 to 19 s as the firefighters became increasingly familiarized with the task. As expected, data also shows that smaller rooms contributed to shorter searching times. Most participants could manage a maximum of three rooms, with wayfinding confusion manifested after they had searched through the third room. These findings are crucial for the design of fireground strategies and training. © 2015 Springer Science+Business Media New York

Jiufen's orographic and geological characteristics together with frequent typhoons and heavy rain make it potentially vulnerable to landslides. The landslide problems could be disastrous not only to the 2,300 local residents, but also to the constant flow of tourists visiting the town. After the site investigations, it is concluded that both of the colluvium and groundwater are the most important geological factors to the slope stability problems. According to the long-term groundwater level monitoring result, it varied from 8m to 12m during the period of typhoon and heavy rainfall. And the displacement induced by the groundwater level rising was found. Four underground flow lines were located based on the resistivity image profiling and self-potential investigation. Then five water collection wells were planned to construct according to the locations of underground flow lines. The level lowered down about 15m after the wells completed and the slope became stable. It is suggested that the depth of colluvium in Jiufen area needs to be investigated in more detail. © 2016, Southeast Asian Geotechnical Society. All rights reserved.
