The effects of the basement storey on the seismic behavior of RC buildings built on near-surface alluvial soft soil are studied in this study. Numerical building models with and without a basement and with different numbers of stories are developed. Time-history dynamic analysis of the structure–soil models was performed using the specialized geotechnical software package PLAXIS-2D. In the first phase of the finite element analysis, the settlement on the soil under the static loads of the building was determined. In the second phase, the earthquake responses of RC buildings with and without a basement storey in terms of lateral displacement were examined by considering the determined stresses after the static loading. The results of the numerical models demonstrate that when the height of the RC buildings is increased, the seismic response of RC buildings without basement storey is detrimentally affected.

地下室层对钢筋混凝土建筑在软表面上的地震响应的影响

本研究研究了地下室层对建造在近地表冲积软土上的钢筋混凝土建筑物抗震性能的影响。开发了带地下室和不带地下室以及不同层数的数值建筑模型。结构-土壤模型的时程动态分析是使用专门的岩土工程软件包 PLAXIS-2D 进行的。在有限元分析的第一阶段,确定建筑物静载荷下土壤上的沉降。在第二阶段,通过考虑静载荷后确定的应力,检查有和没有地下室层的 RC 建筑物在横向位移方面的地震响应。数值模型的结果表明,当钢筋混凝土建筑物的高度增加时,
