A Performance-Based Earthquake Engineering (PBEE) assessment methodology is being used to study the impact of long-term material degradation on seismic performance of reinforced concrete bridges. The methodology, currently under development by the Pacific Earthquake Engineering Research Center, is being applied to an overpass with typical California highway details, and preliminary results are ...

This paper summarizes the initial developments of a research program that is underway to evaluate the efficacy of passive settings to seismically protect sets and pieces of equipment of essential facilities. Specifically, this paper presents case studies based on detailed numerical analysis using models that were validated with available experimental data. The case studies confirmed that: 1) am...

All the existing loading protocols have been developed independently of the value of the behaviour factor q that the structure has been designed for. Conservatively, a single loading protocol is adopted, for all q values, based on the structural system with the most onerous cumulative seismic demands. However, analyses conducted by the authors, show that imposed cumulative seismic demands decre...

Abstract. Past seismic events worldwide demonstrated that damage and death toll depend on both the strong ground motion (i.e., source effects) local site effects. The variability of earthquake distribution is caused by stratigraphic and/or topographic setting buried morphologies (e.g., irregular sub-interface between soft stiff soils) can give rise to amplification resonances with respect expec...

Abstract This chapter deals with all the precious documented recently published and unpublished studies that address seismic situation earthquakes in State of Kuwait. Kuwait is geographically geologically situated northeastern part Arabian Peninsula. In addition to being close famous Zagros belt earthquakes, local sources inside make it always vulnerable earthquakes. We will review instrumental...

A novel hybrid method coupling genetic programming and orthogonal least squares, called GP/OLS, was employed to derive new ground-motion prediction equations (GMPEs). The principal ground-motion parameters formulated were peak ground acceleration (PGA), peak ground velocity (PGV) and peak ground displacement (PGD). The proposed GMPEs relate PGA, PGV and PGD to different seismic parameters inclu...

This study develops a comprehensive seismic risk model for the city of Chania, in Greece, which is located ina highly seismic-prone region due to occurrenceof moderate large earthquakes because nearby major subduction zone between African and Eurasian tectonic plates. The main aim reduce area by incorporating spatial distribution near-surface shear wave velocity soil classification, along with ...

Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...

We use the spectral-element method to simulate strong ground motion throughout the Taipei metropolitan area. Mesh generation for the Taipei basin poses two main challenges: (1) the basin is surrounded by steep mountains, and (2) the city is located on top of a shallow, low-wave-speed sedimentary basin. To accommodate the steep and rapidly varying topography, we introduce a thin high-resolution ...

Abstract Research on new seismic sources and data has already performed in 2016 to 2017. Four shallow crustal fault were observed surrounding the city of Semarang, capital Central Java Province, Indonesia. The parameters related with mechanism (reverse fault) maximum magnitude prediction (6.5 Mw) for each was also released based 2017 research. Following this research, structural evaluation espe...
