复杂体形高层建筑,阴角部位的楼板常发生较严重的震害,其抗震分析应该包含楼板水平地震内力的计算。地震区的简单平面高层建筑,哪些情况可以采用装配式楼板,也需要通过楼板接头的抗震强度验算来判定。本文提出“串并联多质点系”力学模型及相应的数学模型,给出在地震作用下高层建筑各层楼板水平变形和内力的通用计算方法。此外,还选取了一定数量的框-墙结构高层建筑实例,对可能影响楼板水平剪力数值的各种因素,进行了系列的地震反应分析。 In complex high-rise buildings, the floor of the internal corner often suffers from severe earthquake damage. The seismic analysis should include the calculation of horizontal internal seismic forces. In a simple flat high-rise building in an earthquake area, the prefabricated floor can be used in some cases, and it is also required to check the seismic strength of the floor joints. This paper proposes a “series-parallel multi-particle system” mechanical model and its corresponding mathematical model, and gives a general calculation method for the horizontal deformation and internal forces of the floors of high-rise buildings under seismic action. In addition, a number of box-wall high-rise building examples were selected to conduct a series of seismic response analysis on various factors that may affect the horizontal shear value of the floor slab.
