黏弹性阻尼器在轻型门式钢架中的应用

Application research of the viscoelastic dampers in portal frame with light steel structure

以轻型门式钢架结构为研究对象,分析了黏弹性阻尼器的动力特性,建立了计算模型,采用目前通用的大型有限元分析软件ANSYS,建立了有吊车荷载作用的单层单跨门式钢架结构和消能减震结构两种不同的结构模型,并选取Elcentro地震波,在不同柱距下对两种结构模型进行了罕遇地震下的非线性时程分析,通过对计算结果的分析最终得出一些有益的结论。

Introduction of the mechanics performances and calculation model with viscoelastic dampers and energy dissipation braced Is put forward. Portal frame with crane、eccentrically and energy dissipation braced Portal frame with crane were analyzed by using the finite element analytical software ANSYS. At the effects of seismic waves Elcentro, the nonlinear time-history analysis at the scarce earthquake. The results are obtained after these analysis and comparison.
