Seismic and Structural Behavior of Building with Different Combination of Bracing

Linu Shaji, Sreedevi Lekshmi

Abstract: Steel structures played an important role in construction industry. It providing strength, stability and ductility. A study regarding the seismic response of steel structures is necessary. In the present study, modeling of the steel braced structures with different combination of bracing and analyses structure using STAAD pro v8i software. Bracing element in structural system plays vital role in structural behavior during earthquake. In this study there are four types of bracing are used. Such as X bracing, V bracing, inverted V bracing, and knee bracing. The combinations from these bracing are X and V type bracing, X and inverted V type bracing, X and Knee type bracing, V and inverted V type bracing, V and Knee type bracing, Knee and inverted V type bracing. Response spectrum method is used for seismic analysis. Comparison between the seismic parameters such as base shear, roof displacement, storey drift, for steel frame with different combination of bracing are studied.
