摘　　要：提出多高层钢框架-支撑体系在水平荷载作用下内力和变形的计算应依支撑的变形型式的不同而采取不同的计算方法.并重点分析了各类支撑在不同荷载作用下的的变形特点,从而划分其变形型式,作为选择内力和变形计算方法的依据.Different simplified methods should be adopted when compute the internal forces and top lateral displacement under different brace deformation mode for steel frame-brace system computation. Emphases are given to the brace deformation features under different loads, and deformation features are classified to give basis upon the analytical methods adoption for internal forces and deformation.
