程序会输出各方向的模态参与系数以及模态质量和模态刚度。 6)反应谱分析模态信息(Response Spectrum Modal Info)。此表仅在反应谱分析之后输出,输出结果包括各阶模态下的阻尼、谱加速度、模态振幅。 4. 小结 本文介绍特征值向量法的基本定义,简单介绍了静力修正的基本原理,静力修正用较少的模态数量即可得到较为精确的...
In this, present G+10 storied RCC structure is taken for earthquake analysis. Two types of structure Bare frame & X-braced frame are considered for the study. Response Spectrum Analysis is carried out using ETABS software. The parameters considered for the analysis are Base shear, Story drift ...
上一篇博文《ETABS 2015人工波功能初步测试(一)》初步测试了ETABS 2015中人工波功能,可以发现,ETABS2015在函数(function)模块增加的与指定反应谱匹配(Matched to Response Spectrum)的函数定义方法能生成与指定目标反应谱匹配的人工波。本节继续对生成的人工波特性做一下测试。

There are plenty of comments and literature on what to do with the results (i.e. scaling it based on some comparison of RSA shears versus some percentage of static linear static analysis shears). But I still have trouble answering this basic question: What information does a RSA give you ...
This model seems like a mess, however I'm just trying to verify my base shear through a response spectrum analysis. I've attempted it several times, and at first I was getting a base shear of ~200000kN, then I ended up decreasing that to 80000kN (still ridiculously large), and ...
