【摘要】 对于水平力作用下的高层单跨对称框架,本文提出了柱中点弯矩一次传递的计算方法,使内力分析及水平位移计算可用表格方式系统地进行。计算简易、校核方便,精确程度可“由计算人掌握。此法可用于不规则分布的、作用于各层楼盖处的水平外力和柱刚度随楼层而变化的框架。本文对框架底层柱脚不同的支承情况(固支、铰支及弹性支承)的计算,提出了处理办法,并对梁柱刚度比与框架水平位移是否具有纯剪变形的性质,通过算例,表示了初步的看法。更多还原

【Abstract】 A precise method to determine the column center moment at each story of a symmetrical two--column bent subjected to horizontal loads is presented. The calculation of redundant moments and story drifts becomes rather simple and can be carried out systematically in a tabular form. This method is applicable to bents with different supporting conditions and with column stiffness varying with the story.Finally the "Pure Shear" assumption of the bent deformation is discussedbriefly with numerical examples.更多还原
