Volume 14. Risk, Governance and Society
The collected papers in this volume integrate the results from current research efforts in earthquake engineering with research from the larger risk assessment community. The authors include researchers from the major U.S. earthquake centers and some from abroad as well as programmers and analysts from leading insurance and risk assessment firms. Four key components of risk assessment and decision support software are analyzed in detail in the papers: treatment of uncertainty, loss assessment, modeling of seismic mitigation strategies, and visualization of risk and uncertainty. Contributions come from senior experts in the natural hazards research community, as well as from senior scholars from other related fields. The volume lays out a road map for future developments in seismic risk modeling and decision support and helps earthquake engineering researchers position their work within the family of risk analysis tools and techniques.

Generating a quality finite element mesh is difficult and often very time-consuming. Mesh-free methods operations can also be complicated and quite costly in terms of computational effort and resources. Developed by the authors and their colleagues, the smoothed finite element method (S-FEM) only requires a triangular/tetrahedral mesh to achieve more accurate results, a generally higher convergence rate in energy without increasing computational cost, and easier auto-meshing of the problem domain. Drawing on the authors’ extensive research results, Smoothed Finite Element Methods presents the theoretical framework and development of various S-FEM models.
After introducing background material, basic equations, and an abstracted version of the FEM, the book discusses the overall modeling procedure, fundamental theories, error assessment matters, and necessary building blocks to construct useful S-FEM models. It then focuses on several specific S-FEM models, including cell-based (CS-FEM), node-based (NS-FEM), edge-based (ES-FEM), face-based (FS-FEM), and a combination of FEM and NS-FEM (αFEM). These models are then applied to a wide range of physical problems in solid mechanics, fracture mechanics, viscoelastoplasticity, plates, piezoelectric structures, heat transfer, and structural acoustics.
Requiring no previous knowledge of FEM, this book shows how computational methods and numerical techniques like the S-FEM help in the design and analysis of advanced engineering systems in rapid and cost-effective ways since the modeling and simulation can be performed automatically in a virtual environment without physically building the system. Readers can easily apply the methods presented in the text to their own engineering problems for reliable and certified solutions.

Hi!
As part of our requirement in our school, we have to present a detailed engineering design of
(a) Gasoline Station (minimum of 8 units)
(b) Petroleum Storage Facilities
Does anyone have this? Thanks guys! Replies will be highly appreciated.

Title Testing fresh concrete. Self-compacting concrete. L box test
Descriptors Concretes, Cement and concrete technology, Self-compacting, Flow, Flow measurement, Flow rates, Bars (materials), Test equipment
Abstract To assess the passing ability ratio of self-compacting concrete, measuring the ability to flow through tight openings including spaces between reinforcing bars and other obstructions without segregation or blocking. The L box test is an alternative to the J-ring test but the result is not directly comparable.

Does anyone have waterproofing detail around a plunged steel column and basement raft/slab interface? The Plunge column often use for top-down basement construction or supporting prop/strut which support retaining wall. Steel Construction Institute (SCI) has a publication titled 'Steel Intensive Basements Guide' may have some detail published. This can not be varified as I do not have the publication.
Seismic Design of Precast/Prestressed Concrete Structures
Year of Publication: 2007
Number of Pages: 487
Published by: Precast/Prestressed Concrete Institute
Authors: Ned M. Cleland and S.K. Ghosh
First Edition
This manual provides current information on precast design within the context of the code requirements for seismic design, ongoing research, and the authors’ opinions about appropriate practice.
It must be emphasized that this manual, although sponsored by PCI, does not represent a consensus recommended practice. It represents opinions of the authors concerning some ways in which precast design may be carried out to conform to code requirements and to perform acceptably under seismic effects.
The methods and procedures discussed and illustrated are not a substitute for the sound professional judgment of engineers familiar with both earthquake effects and precast concrete construction. This manual will provide the engineer with acceptable ways of applying the seismic design provisions of ACI 318-02, ASCE 7-02, and IBC 2003 to precast concrete structures.
