A PROJECT ON SEISMIC EFFICIENCY OF COMBINATION OF BRACING FOR STEEL BUILDING BY ETABS SOFTWARE

Abstract

Earthquake-resistant structures are structures designed to protect buildings from earthquakes. While no structure can be entirely immune to damage from earthquakes, the goal of earthquake-resistant construction is to erect structures that fare better during seismic activity than their conventional counterparts. According to building codes, earthquake-resistant structures are intended to withstand the largest earthquake of a certain probability that is likely to occur at their location. This means the loss of life should be minimized by preventing collapse of the buildings for rare earthquakes while the loss of the functionality should be limited for more frequent ones. Now a day’s steel bracings technique and shear wall systems are generally using for designing of earth quake resistant structure due to simple construction methods, easy to install and they are reduces the deflection and shear in past studies the earth quack resistant structure is designed by using steel bracings or shear wall systems in present study a comparison made between these two systems along with general building in high seismic zone.
In the present study a G+11 story steel building is modeled by using ETABS software and analyzed in response spectrum analysis and the comparison is made between the general building, steel bracings building to design the earth quake resistant structures design. The results like story drift, story shear, story moment, building torsion, time period, and model stiffness were compared for the different building models namely general building, bracings at corner, bracings at center and alternatives bracings locations..
