Arch bridge construction technology has made a great deal of progress in Japan since the 1960s. With cantilevering construction, temporary steel arches are generally used to develop arch action as soon as possible. This approach is particularly advantageous in earthquake prone areas. Temporary stays and ground anchors can also be reduced because of the earlier arch action provided by the temporary steel arch. Such temporary arches often use a box design without filling the interior of the box with concrete, adopting this approach because less concrete is required for the arch rib. This paper also considers a new design concept for half-through arch bridges, which have the deck located at an intermediate level of the arch. Because of construction difficulties, there are not so many examples of this type of bridge using concrete arches. With the new design concept, the center section of deck inside the arch provides part of the arch action. This solution makes construction easier with steel box arch technology. Finally, some new applications of arch bridge technology are shown.

Microfractures occurring in a rock sample that are called acoustic emission (AE) events show some similar features to earthquakes. However, it remains to be shown whether or not AE equate to ultramicroearthquakes. In this study, we show the existence of magnitude -7 level earthquakes based on seismological analyses of AE source parameters. Advances in multichannel, broadband, high-speed continuous recording of AE under seismogenic pressure conditions has facilitated increasingly robust measurement. Source parameters of AE show that AE events satisfy the same scaling relationship as natural earthquakes in which seismic moment is inversely proportional to the cube of corner frequency. This result suggests that both millimeter scale fractures and natural earthquakes of kilometer scale ruptures are highly similar as physical processes. Hence, AE events can be interpreted as ultramicroearthquakes having a magnitude of about -7. These results demonstrate that laboratory observation is an effective approach in studying natural earthquake generation process. Key Points The magnitude -7 level earthquakes are identified in a laboratory experiment Ruptures from kilometer to millimeter scale satisfy the same self-similar relationship Broadband recording of AE events under a triaxial condition has been succeeded ©2014.

To establish an impact-resistant design procedure for reinforced concrete (RC) structures based on the performance-based design concept, an evaluation method for the impact-resistant capacity of the structures needs to be developed. Until now, a particular method for beams has not yet been specified worldwide. To achieve this, falling-weight impact tests on a total of 36 beams with varying section parameters were conducted and the key factors for better representing the impact behavior of the beams were investigated. Two empirical equations were derived based on the experimental results. By using these equations, the required static flexural load-carrying capacity of an RC beam may be determined by specifying the limit state with the maximum and residual deflections of the beam.

Once ice forms in highly saturated concrete material, internal tensile stress will be generated and causes damage to the material, which is a serious problem for concrete structures in cold and wet regions. On one hand, each component (porous body, ice and liquid) should satisfy the compatibility of stress and strain, which has been discussed by the poromechanical theories. On the other hand, if some empty voids exist, the hydraulic pressure will release when liquid water escapes from the expanded area according to Darcy's law. Recent closed freeze-thaw tests on the saturated mortar showed a consistent tendency: as the number of freeze-thaw cycles (FTC) increases, the deformation changes from the expansion to the contraction. In order to make clear the physical and mechanical changes during this process, a more comprehensive hydraulic model is developed, which combines both the mechanisms mentioned above. The estimated strain behavior by this model is in a good agreement with experimental measurements, and also, it has good potential and is more flexible to be applied to different cases such as different saturation degrees and cooling rates. The permeability change can be also considered in this model as a reflection of frost damage level. Copyright © 2015 Japan Concrete Institute.

This paper describes the conceptual designs of a facility for storing, in the form of a clathrate hydrate, hydrogen produced in an industrial complex area. We recently reported the first engineering investigation of hydrate-based hydrogen storage, focusing on the conceptual design of hydrate production plants applicable for the large-scale stationary storage in urban or industrial complex areas (Nakayama et al., Energy Fuels 2010;24:2576-2588). This paper complements the previous study by presenting conceptual designs of underground hydrate-storage silos each to be coupled to a hydrate production plant. Several different types of underground silos each having a 35,000 m3 capacity were planned and designed on a construction-engineering basis, which included (a) a tunnel-type silo consisting of several levels radially arranged around an access shaft, (b) a tunnel-type silo consisting of several levels that branch off from a single access level connected to an access shaft, and (c) a vertically-oriented cylindrical tank-type silo. For each type of silo, we have specified the hydrate loading and unloading equipment as well as the cooling system, and have estimated the construction cost.

A unique suspension method developed over a period of more than 10 years produces a rational structure in the form of a single-span composite truss bridge. For this structure, the steel truss and concrete deck are constructed on the spanning cables. During construction the horizontal forces of these cables are anchored into the ground, but after completion of the bridge the forces are transferred to concrete upper and lower chords as prestressing forces. A single-span composite truss bridge of this type can be constructed without temporary supports or falsework. Using this method to bridge a deep valley produces benefits in terms of both construction costs and sustainability. A single-span bridge requires less excavation than other bridge types, and utilizing a composite truss with this construction method can minimize the environmental impact of the construction.

IABSE Conference, Nara 2015: Elegance in Structures - Report | Year: 2015

As Roman architectures needed three elements, structural elegance of bridges is the combination of three elements of beauty, functional, structural and beauty of form. Besides, past innovations that added ingenuity and creativity to structural elegance can be considered sustainable. A structure becomes sustainable by combining structural elegance with creativity, which we called structural sustainability. What is the relationship between structural elegance and sustainability? This paper considers how to realize more elegant bridges.

Multi-Span Large Bridges - Proceedings of the International Conference on Multi-Span Large Bridges, 2015 | Year: 2015

Some examples of multi-span extradosed bridges in Japan are introduced together with their structural features. Furthermore, a new solution to extend the span length of extradosed bridges to around 500 m is proposed, using a new technology called the butterfly web. The structural behavior of a multi-span long extradosed bridge, including the results of wind tunnel tests, is discussed. © 2015, Taylor & Francis Group, London.

A fully three-dimensional finite difference code is developed for simulating wave and fracture propagation in solids and it is used to study the physical process associated with blasting demolition of reinforced concrete (RC) structures on a PC basis. The code is validated by comparing the numerical results with those obtained by a blasting experiment using a RC beam specimen in the field. A real example of blasting demolition of piers of a road bridge is shown and the usability of the code is tested. Detailed computations have revealed that the use of a simple tensile fracture criterion can reproduce the observed fracture patterns precisely. © 2010 Elsevier Ltd. All rights reserved.
