关于钢框架-剪力墙（支撑）体系中框架柱标准反弯点高度比y0的取值

STUDY ON THE REFLECT POINT HEIGHT RATIO Yo EVALUATION OF THE FRAME COLUMN OF THE STEEL FRAME-SHEAR WALL (BRACE) SYSTEM

根据协同工作原理分析框架竖向的剪力分布特点,对钢框架-剪力墙(支撑)体系中框架柱标准反弯点高度比y0的取值问题,提出应按仅在框架顶点作用一集中水平力时计算y0值,并推出仅在框架顶点作用一集中水平力时,框架柱标准反弯点高度比y0的计算公式,可供手算和电算使用.

Analysis is carried out on the vertical shear distribution features under compatible displacement. As to the evaluation of frame column typical reflect point height ratio y0 of steel frame- shear wall（brace）system, it is proposed that the evaluation be conducted on condition of lateral concentrated force upon the top roof of frame only. And the formula to calculate the typical reflect point height ratio y0 under such conditions be proposed, it is suitable for both manual and computer use.
