Introduction The heterogeneities in the crust and upper mantle structure as well as the complex source rupture process have an important influence on regional seismic wavefield, particularly for high-frequency waves. Moreover small-scale heterogeneities such as for the sedimentary basin introduce significant amplification of ground motion, which lead to long ground shaking over several minutes ...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

By Timothy Phillips Vaughan, MS. Washington State University May 2010 Chair: David I. McLean This research evaluated the structural performance of reinforced masonry shear walls conforming to requirements given in the 2008 MSJC Building Code Requirements for Masonry Structures under cyclic lateral loading. Seismic design provisions in the 2008 MSJC provide prescriptive requirements for three di...

Structural engineers, researchers, code committees, and regulatory bodies have become increasingly interested in performance-based design of structures, systems, and components (SSCs) in the past few years. This has been demonstrated by the publication of codes for the performance-based design of traditional buildings, and by publication of a consensus standard for evaluating the seismic perfor...

As part of the development a European Seismic Risk Model 2020 (ESRM20), spatial and temporal evolution seismic design across Europe has been studied in order to better classify reinforced concrete buildings (which represent more than 30% approximately 145 million residential, commercial industrial Europe) map them vulnerability models based on simulated design. This paper summarises model that ...

The numerical simulation of shallow water acoustic propagation has given rise to a wide variety of modeling techniques with various degrees of accuracy. One technique, involving finite difference methods, is more commonly used in the description of seismic propagation but also occurs in the shallow water propagation literature. This word reported here involves the application of finite differen...
