Structural damage can be controlled in performance based seismic design (PBSD) according to the requirement under a certain hazard level. During strong ground motion (GM) such buildings suffer minor to major damages depending on the shaking level of GM. The available damage assessment methods are complex, tedious and time-consuming procedure. In the present study, a simplified empirical model h...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...

Multi-story, reinforced-concrete (RC) building structures with soft stories are highly vulnerable to damage due earthquake loads. The story causes a significant stiffness irregularity, which has led numerous buildings collapsing in previous seismic events. In addition the structural collapse, failure of non-structural components (NSCs) also been observed during past earthquakes. light this, thi...

A cyclic loading test of a steel moment-resisting frame (SMRF) with nonstructural components was conducted to evaluate the seismic performance buildings subjected multiple earthquakes. The specimen is single-floor, one-span substructure intermediate story typical current middle- or low-rise building in Japan. Two specimens were tested. structural systems these two same, but attached different. ...

Analytical seismic response of multi-story building supported on base isolation system is investigated under real earthquake motion. The superstructure is idealized as a shear type flexible building with lateral degree-of-freedom at each floor. The force-deformation behaviour of the isolation system is modelled by the bi-linear behaviour which can be effectively used to model all isolation syst...

In the study, weight efficiency of Triple Friction Pendulum Bearing (TFP) Isolators is investigated on optimal planar steel frames. For this investigation, an optimization program based Artificial Bee Colony (ABC) algorithm have been developed for study. design frames, structure should satisfy strength, inter-story drift, top-story drift and geometric requirements that are implemented from LRFD...
