Journal of Structural Engineering May 2011 . Seismic Response of RC Frames with Steel Braces. The Seismic Investigation of Off-Diagonal Steel Braced RC pdf internal steel bracing of rc framesSteel bracing may be used to enhance the seismic strength of RC frames. Concentric steel bracing generally reduces ductility, which is a key component of seismic design. To overcome the problem, ductile steel brace-RC frame systems are therefore usually introduced in the form of eccentric braces.

A Study on Outrigger System in a Tall R.C Structure

reinforcing steel bars and concrete are the two key materials used in reinforced concrete building. A typical RC tall building is made of horizontal and vertical member and supported by foundation on rest of the ground. To resist the earthquake forces the RC frames plays a vital role. TheA comparative study on effect of Lateral loading on steel pdf internal steel bracing of rc framesSteel 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.AISC Home | American Institute of Steel ConstructionAISC Home | American Institute of Steel Construction
