摘要
本文通过铝合金穹顶网壳的静力试验 ,研究了网壳结构在荷载作用下的力学性能。并与采用杆系有限元法计算的理论结果进行了比较 ,得出铝合金网壳结构在进行力学分析时 ,其力学模型与钢网壳一样 ,均可以非线性空间梁单元作为计算单元。本试验的结论可为铝合金穹顶网壳在我国的推广使用提供分析和设计依据。
Through the static test of an aluminous-alloy dome, its mechanical behaviors were studied. A comparison between the theoretical results with non-linear finite element method and the test values was made. It shown that the non-linear three-dimension beam element could be treated as computational model to analyze this type of domes. The conclusion of the test can apply in the design and analysis of aluminous-alloy dome in the future.
