摘　　要：探讨了防屈曲约束支撑(BRB)和偏心支撑框架结合形成防屈曲约束-偏心支撑在大震作用下的共同耗能减震。通过有限元软件sap2000时程分析得出:防屈曲约束支撑在平面上不宜满布,应尽量间隔布置,在立面上应该交错均匀布置,切忌将防屈曲约束支撑集中布置在某几层。The energy consumption and shock adsorption of both the buckling restrained brace（ BRB） and the eccentric braced frame under big seismic action were discussed. Through time history analysis of the finite element software SAP2000,it was given that,the buckling restrained braces should not be fully arranged horizontally but at intervals as far as possible,they should be staggered evenly and vertically,avoiding arrangement of a buckling constraint support in a few layers.
