高层剪力墙结构开设角窗后底层内力分析

Analysis on ground floor internal force after setting up angle window for high-rise shear-wall structures

对开设转角窗的塔楼结构建立不同的力学模型,应用PMSAP软件计算了结构开洞后转角部位墙体底层内力的变化情况,并对计算结果进行了分析,表明转角连梁的跨高比是对结构内力的重要影响因素之一,设计时应重点考虑。

It establishes different mechanical models for setting up angle window of tower building, calculates the ground floor internal force changing condition at angle part after structural holing by applying PMSAP software, analyzes the calculating results, which shows that： the span ratio of angle window integrating girder is one of the important influential factors for structural internal force. Therefore, it should be considered carefully.
