| Abstract: | Braced steel frame is a normal structural system in high-rise steel buildings.The development of the braced steel frame is introduced.Based on a practical project,the influences of steel braces and bucking restrained braces on the elastic and elasto-plastic behavior are analyzed.By pushover analysis,the seismic behaviors of two frames are studied.And the buckling restrained braces used in eccentrically braces steel frames are analyzed. |
