基于PKPM反应谱法的金属阻尼器分析方法研究

Research on the analysis method for mental energy dissipation device based on response spectrum

近年来地震频发,消能减震阻尼器的工程应用日益受到重视,其中金属阻尼器综合性能突出。但目前我国结构分析仍以反应谱法为主,且广泛采用的结构分析软件PKPM(PMCAD+SATWE)不能自动修正金属阻尼器分析模型的附加阻尼及附加刚度,难以完成金属阻尼器分析。针对这一问题,本文对结构分析软件PKPM(PMCAD+SATWE)进行了二次开发,实现了对分析模型的自动修正,并且给出了相应的误差评估。

In recent years,earthquake happened more frequently than before. More and more attention has been paid to the application of energy dissipation devices. Among these popular types of energy dissipation device,the mental energy dissipation device is generally the most excellent one. But in China the main structure analysis method is still based on the response spectrum. And the popular structure analysis software named PKPM（ PMCAD ＋ SATWE） cannot automatically adjust the additional damping and stiffness of the analysis mode for the mental energy dissipation device. So it is very inconvenient to perform the analysis of mental energy dissipation device. In order to solve this problem,the authors of this article have redeveloped the structure analysis software named PKPM（ PMCAD ＋SATWE）. The redeveloped software can automatically adjust the analysis mode and the error estimation is also displayed automatically.
