Abstract

Steel bracings are lateral load resisting structural members which help in increase of strength and satisfy both architectural and structural requirements considering gravity and lateral loads. Present analytical research deals with optimum location of bracing and bracing system in unsymmetrical building plan (T-shape) of G+30 storeys by considering both wind and seismic effect. Bracings such as X and single diagonal are compared and provided at various exterior locations of structure. In the present research the comparison is done for five different types of bracings system such as braces are connected within the storey is type 1, In type 2-bracing are connected between two storeys, in type 3-bracing are connected between three storeys, type 4-bracing are connected between four storeys, type 5-bracing are connected between five storeys. The results are compared with bare frame and steel braced structure considering ductility, drift control and torsional effect. The analytical results concluded that providing more stiffness leads to control of drift, reduces ductile nature and increase of torsional effect. Bracings connecting for more than two stories increases ductility, reduces stiffness and reduces torsional effect-compared to bracing connected within the storey.
