利用Ansys大型有限元软件,建立布置了约束屈曲支撑的K8网壳新型减震体系有限元模型。通过非线性时程分析研究了体系在多点地震动输入下的抗震性能,并通过与普通网壳和其在地震动一致激励下的性能相对比,得出约束屈曲支撑在地震动多点激励性的减震性能,给出这种新型网壳体系的合理理论分析方法。
A finite element model of the new shock-absorbing system of K8 net shell with restrained buckling support was established by Ansys large-scale finite element software. The seismic performance of the system under multi-point ground motions is studied by nonlinear time-history analysis. By comparing with the conventional net-shell and its performance under the consistent excitation of ground motions, The performance of this new type of reticulated shell system is analyzed theoretically.
