摘要
为研究芯孔尺寸不同的高层水泥聚苯模壳格构式混凝土墙体抗震性能,为其在实际的工程应用提供可靠的参考依据.采用有限元分析方法,围绕8度地震作用下高层水泥聚苯膜壳格构式混凝土墙体结构的地震动力响应与抗震性能变化规律,对4个芯孔尺寸不同的高层水泥聚苯膜壳格构式混凝土墙体结构进行了对比,发现了不同芯柱直径高层建筑的地震动力响应变化规律,得出在考虑端柱、边柱、转角柱加强,芯孔直径缩小到140mm时,该格构式墙体结构模型在8度基本设防地震下结构的层间位移角较大为1/454,抗震墙最大塑性层间位移角限值为1/120,从而拓宽了这种新型建筑芯孔直径限值要求.
In order to study the seismic behavior of the high rise frame concrete lattice wall with different sizes of core holes, and provide a reliable reference for the practical engineering application, this paper used the finite element analysis method with considering the dynamic response and seismic behavior of high rise the expansive polystyrene granule cement latticed concrete wall under 8 degree earthquake, and carried out a comparison between the 4 top expansive polystyrene granule cement latticed concrete walls with different sizes of core holes. This study obtained the seismic dynamic response rules for the high-rise buildings with different stem diameter, and concluded that when considering the strengthening of end columns, side columns and corner columns, and when the diameter of the core hole is reduced to 140 mm, the layered displacement angle of the structure of the lattice wall structure model under the 8 degree basic anti-earthquake is 1/454. The maximum plastic interlayer displacement angle limit of the seismic wall is 1/120, which broadens the new building core hole diameter limit.
