摘要
多弹簧模型空间梁柱单元可以有效地模拟空间梁柱单元在轴力、弯矩以及剪力共同作用下的响应,反映空间梁柱单元在往复荷载以及地震作用下的滞回性能。介绍了建立多弹簧模型梁柱单元刚度矩阵的理论依据以及该理论的关键公式与矩阵。使用以该单元为主编制的MTS建筑钢结构设计软件的非线性分析模块进行静力非线性以及动力非线性时程算例分析,验证了该单元模拟空间梁柱的准确性以及MTS软件非线性模块的可靠性。
Multi-spring element model is effective in simulating the combined action of axial force, moment and shear force as well as reflecting the hysteretic behavior under the reciprocal load or earthquake load. The theory about establishing element matrix with multi- spring model is introduced. The key formulas and element matrix is also provided. Compare the results of nonlinear subprogram of MTS steel structure design program which is mainly compiled with multi-spring element model and experiment or SAlt2000. The correct of this model and the reliability of MTS program are verified by the comparison.
