Abstract An efficient implementation of the capacity design requires high ductility combined with a low overstrength critical regions. Conventional timber connections do not generally offer such ideal combination, resulting in modest behaviour and relatively factors. Inspired by Buckling Restrained Brace new hold-down has been developed where wall directly acts as casing. The given an adaptive ...
Recently, buckling-restrained braces (BRBs) have been widely implemented as seismic load resistance systems in buildings to enhance their response against dynamic vibration. However, during catastrophic earthquakes, the steel core BRB devices fully yields, which causes lose its functionality. While incorporation of various filler materials, such new high-performance concretes, has potential per...
The present study assesses the seismic performance of steel moment resisting frames (SMFs) retrofitted with different bracing systems. Two structural configurations were utilized: ordinary concentrically braces (OCBFs), buckling-restrained braces (BRBFs). A 7-story and 18-story steel perimeter SMFs were designed with insufficient lateral stiffness to satisfy code drift limitations in high seism...
Depending on the tectonic activities, most buildings subject to multiple earthquakes, while a single design earthquake is suggested in most seismic design codes. Perhaps, the lack of easy assessment to second shock information and sometimes use of inappropriate methods in estimating these features cause successive earthquakes mainly were ignored in the analysis procedure. In order to overcome t...
