铸钢节点力学性能分析时,忽略刚性区的影响,将低估节点各肢面内抗弯刚度;采用铸钢节点实体有限元能够较为准确的模拟铸钢节点的各项力学性能,实现比较困难,工程推广甚为不便。采用刚性材料法,在ANSYS中增大刚性区的弹性模量E,可以得到较为理想的计算结果,且较实体模拟法易于实现。以广州歌剧院钢结构的力学性能计算为算例,对比分析了刚性材料法得到的结果与现场试验结果。
When analyzing the mechanical properties of cast steel joints, ignoring the influence of rigid zone will underestimate the flexural stiffness of each limbs. The solid finite element method of cast steel joints can simulate the mechanical properties of cast steel joints more accurately and achieve more difficult, Project promotion is very inconvenient. Using the rigid material method, increasing the elastic modulus E of the rigid zone in ANSYS can obtain the ideal calculation result, which is easier to implement than the physical simulation method. Taking the calculation of the mechanical properties of the steel structure of Guangzhou Opera House as an example, the results obtained by the rigid material method and the field test results are contrasted and analyzed.
