高层建筑结构分析中对楼板的模型简化

THE MODELING ASSUMPTION OF FLOOR SLABS IN TALL BUILDINGS

在复杂高层建筑结构分析中,对楼板的模型简化至关重要.本文从工程实用角度出发,对楼板给出了多种简化假定,并在高层建筑结构空间有限元分析与设计软件SATWE中实现了这些假定.在使用中可根据工程实际需要,灵活应用.SATWE软件还具有弹性楼板单元自动划分.自动生成各节点主从隶属关系等功能,从而可大大提高复杂高层建筑结构的分析精度和分析效率.

In the analysis and design of complex tall buildings, the modeling assumption of the floor slabs is very important. According to the requirement of engineering practice, a set of modeling assumptions is provided in the three dimensional finite element analysis and design software for tall build-ings-SATWE, which is developed by the PKPM CAD Department, China Academy of Building Research . It might be flexibly used based on the requirement of the project. The elastic slabs can be divided into small shell elements automatically by the program. The analysis precision and efficiency are thus improved greatly.
