基础零应力区的控制

在高烈度地区结构设计中遇到结构整体计算时输出结果中基础零应力区超过规范规定限值的情况。通过分析产生这种情况的原因,按实际情况进行计算复核,并调整设计使建筑物基础零应力区控制指标满足规范要求,保证结构整体稳定。

In the structural design of high intensity area, it is encountered that the zero stress zone of the foundation exceeds the limit value stipulated in the code when the output result of the whole structure is calculated as a whole. Through the analysis of the causes of this situation, the calculation and review is carried out according to the actual situation, and the design is adjusted to make the control index of the zero stress zone of the building foundation meet the requirements of the standard, so as to ensure the overall stability of the structure.
