Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have b...

according to iranian code of practice for seismic resistant design of buildings standard no. 2800, yazd is located in the place with the medium earthquake hazard [1]. due to the position of yazd with many historical and important buildings, maintaining these traditional heritages is an important task in civil engineering field. on account of these mentioned valuable buildings and region potenti...

One of the main tasks of engineers is to design structural systems light and economic as possible, yet resistant enough to withstand all possible loads arising during their service life and to absorb the induced seismic energy in a controlled and predictable fashion. The traditional trial-and-error design approach is not capable to determine an economical design satisfying also the code require...

Although several studies have investigated the effect of degradation on the behavior of structures, investigations on collapse margin ratios are rare in the literature. In this study, the effect of strength and stiffness degradation on collapse capacity of steel moment frames is investigated. The aim is to determine margin of safety against collapse using a probabilistic approach. For this reas...

Calculation of site coefficient and design response spectral acceleration are two important steps in the seismic buildings. According to Indonesian Seismic Code 2019, information requirements for calculations

Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

We present a parallel implementation of a seismic inversion code. Parallelism is exploited at the loop level within the nite diierence modeling, as this is the most time consuming part of the code. We give details of our implementation, and present numerical results. We have reached a performance of 750 MMops on one processor, and over 4 GGops on 16 processors, on a Cray C90.

the main cause of structural damage in buildings subjected to seismic actions is lateral drift. in almost all reinforced concrete (rc) structures, whether designed with walls or frames, it is likely to be the code drift limits that control the design drift. the design drift limits and their contribution to damage may be represented indirectly through the material strain limits. the aim of this ...

Within Geophysics, seismic methods are an essential tool for petroleum and gas exploration. They produce images of the earth's interior and let explorationists analyze the geological structure of the underground. The memory and time requirements of seismic calculations suggest parallel implementations. In Fortran, however, parallel program code often not only lacks maintainability and reusabili...
