摘要
主要研究了网格结构在拆除铸钢节点的胎架后的稳定性。通过采用SAP2000建模,对该网格结构进行模拟分析,得出铸钢节点在拆除胎架后3个方向的线位移,与利用全站仪实测数据对比,总结节点位移的规律,以及对实测数据的合理性进行判断,分析结构的稳定性。结果发现数据基本合理,符合一般规律性。实测数据与计算值基本吻合。
The stability of the grid structure was studied in this paper after dismantling the steel structure for sustaining the cast steel joints. SAP2000 was used to analyze the grid structure, The three direction displacement of the cast steel joints was obtained, According to the data from the experiment in the building site and the data from simulation analysis, we summarized rule of the joints displacement, The rationality of the data from the experiment was judged and the stability of structure was analyzed. The data was found rationality from the outcome and accorded with general rule, The experiment data tallied with theory value.
