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...

This study deals with performance-based design optimization (PBDO) of steel moment frames employing four different metaheuristics consisting of genetic algorithm (GA), ant colony optimization (ACO), harmony search (HS), and particle swarm optimization (PSO). In order to evaluate the seismic capacity of the structures, nonlinear pushover analysis is conducted (PBDO). This method is an iterative ...

Seismic isolation systems for buildings design are not as popular in the seismically active developing countries they developed ones. Several factors contribute to this, namely lack of knowledge on benefits seismic systems, unfamiliarity with procedure, and absence relevant building codes that provide guideline using system such countries. Recently, Indonesian code has been updated included str...

Abstract—The optimal design procedure of buckling restrained braces (BRBs) in reinforced concrete (RC) building structures can provide the distribution of horizontal stiffness of BRBs at each story, which minimizes story drift response of the structure under the constraint of specified total stiffness of BRBs. In this paper, a simple rule is proposed to convert continuous horizontal stiffness o...

The effect of aftershocks on the fragility single-story masonry structures is investigated using probabilistic seismic demand analysis Finite element models an unreinforced (URM) structure and a confined (CM) are established their response characteristics when subjected to mainshock, aftershock, mainshock-aftershock sequence then comparatively investigated. effects use confining members studied...

Abstract In this paper, three different damage indexes were used to detect nonlinear damages in two adjacent Reinforced Concrete (RC) structures considering pounding effects. 2-, 4- and 8-story benchmark RC Moment Resisting Frames (MRFs) selected for purpose with 60%, 75%, 100% of minimum separation distance also without any in-between gap. These analyzed using the incremental dynamic analysis ...
