Low Impact Development 2010: Redefining Water in the City - Proceedings of the 2010 International Low Impact Development Conference | Year: 2010

Bay-Friendly Landscaping integrates Low Impact Design (LID), into a holistic, sustainable, watershed approach to landscaping that addresses current environmental, economic, health, and safety issues, including stormwater management and protection of San Francisco Bay water quality. More than 30 new landscapes, including libraries, community centers, fire stations, community colleges, multifamily housing and streetscapes, have been designed and constructed to meet the Bay-Friendly Landscape standards, with many of these projects also meeting both LID and LEED™ goals. Project goals and features, including those to manage stormwater, are described for two Bay-Friendly Rated landscapes in the East Bay. Ohlone College's new campus in Newark, CA, for the Center of Health Sciences and Technology, designed to achieve the LEED™ Platinum and the Bay-Friendly Ratings, includes weather-based irrigation controllers, planting with low level water requirements, an integrated pest management policy, a Bay-Friendly maintenance program, and multiple strategies to collect and filter stormwater. Sara Conner Court is a community of 57 affordable rental homes in Hayward, CA. The site directs all stormwater runoff toward lawns, planting beds and bioswales, moderates building temperatures and reduces heat island effect with effectively placed trees. Parking areas without curbs and grass-porous pavement in courtyards increase the infiltration and filtration of stormwater. © 2010 ASCE. Source

In the Design field Strategic Design is emerging as a technological resource able to promote inclusion, access and participation. This approach seems to be able to help NGOs with project decisions in unstable contexts. Through an action-research, Strategic Design techniques have been applied in a Rio de Janeiro slum in collaboration with a NGO. The project aimed at the collective revitalization of an abandoned square. The article focuses on the temporal dimension of projects development. Field experience outlined divergences among the timing of the designer's action, of the organization's dynamics and of the social change itself. They create a conflict environment and challenge the project impact. Concepts from Strategic and Participatory Design, Project Management and social complex contexts lead to a reflection on this Design approach and on the challenges to integrate the designer's action in the organization structure.

Most published studies on inelastic earthquake response of non-symmetric buildings are based on simplified inelastic, highly idealized models, while general conclusions regarding the inelastic torsional response of multistory building are still lacking. This paper aims to provide a useful contribution in the study of the torsional response of real irregular buildings. To this aim, the manuscript reports the comprehensive study on the seismic vulnerability of an irregular RC building: the hospital building of Avezzano (L’Aquila Italy). For this multi-story building, which is irregular in both plan and elevation, the application of nonlinear static evaluation procedures is by no means straightforward. The study proposes a nonlinear static procedure based on pushover analysis under the multimodal distribution of lateral loads and a capacity spectrum method. This pushover procedure accounts for mass distribution, higher modes contribution and mode-shapes correlation. Furthermore, due to its non-iterative feature, it avoids problems of non-convergence and multiple solutions of the conventional capacity spectrum method. Applied to a real case study, the procedure is used to investigate, in a 3D plan irregular building, the sensitivity of torsional inelastic response to lateral force distribution, higher modes contribution, accidental eccentricity and controlled point for monitoring the target displacement. © 2015, Institute of Engineering Mechanics, China Earthquake Administration and Springer-Verlag Berlin Heidelberg.

High to ultra-high purity hydrogen may be needed for the durable and efficient operation of fuel cells. In the production of hydrogen, CO 2 is also produced. The SMR process used in centralized plants emits more than twice the CO 2 than hydrogen produce. To avoid CO 2 emissions into the atmosphere, CO 2 can be concentrated, captured, and sequestered; sequestration concepts and technologies are relatively new and there is no long-term test evidence to prove that these technologies will be successful. Hydrogen is produced by the SMR process in large centralized industrial plants for use in numerous applications, including chemical manufacturing and petroleum refining. R& D programs are currently investigating the development of small-scale SMR technologies to enable the development of small-scale, distributed hydrogen production, and delivery infrastructure. This is an abstract of a paper presented at the 2012 AIChE Spring Meeting and 8th Global Congress on Process Safety (Houston, TX 4/1-5/2012). Source

A detailed investigation of the weight of each non linear term of the Green-Lagrange strain displacement equation is presented, with reference to the buckling of orthotropic, both flat and prismatic, Mindlin plates. Usually in the literature, in buckling analysis only the second order terms related to the out-of-plane displacement are considered. Such heuristic simplification, known as von Kármán hypothesis, starts by the consideration that the buckling mode of a flat plate is described by dominant out-of-plane displacement and disregards the non-linear terms of the Green-Lagrange strain tensor depending on the in plane displacement components, whose role is confined to first order, say pre-critical, deformation. The present paper shows that disregarding the non linear terms related to the in-plane strain-displacement is equivalent to neglect shear induced rotation. In the work, the governing equations are derived using the principle of strain energy minimum and the differential equations solution is gained by using the general Levy-type method. The obtained results show that the von Kármán model overestimates the critical load when, in buckling mode, magnitudes of shear rotation, in-plane and out-of-plane displacements are comparable. © 2014 Elsevier Ltd.
