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 ...
(1)振型型分解法,首先是进行模态分析,有多少个动力自由度,理论上就有多少个模态,相应的有多少个周期(频率),及振型。 (2)振型向量关于质量矩阵及刚度矩阵正交。因此,无阻尼运动方程可以实现解耦,将耦合的运动方程,解耦为多个广义单自由度运动方程。
For nonlinear analysis one typically uses a pushover curve (nonlinear static analysis) or time history analysis (nonlinear dynamic analysis). Both of these, to an extent, can be done in ETABS. Although Perform would bet the more common software for this. JoshPlumSE (Structural) 23 Oct 13 ...
Comparative Seismic Analysis of Regular and Irregular Multistorey Structures with and without Bracings and Shear wall structures with and without shear walls and bracings is included in this discussion which is done using ETABS 2019 software by Response Spectrum Analysis. ...

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 ...
Guidelines for selecting structural systems using dynamic analysis (Response Spectrum Analysis) was the primary motivation for this study. Using ETABS 2016, we modelled and analysed multi-story buildings with different structural systems. In order to model the dynamic reaction of the modelled structures...
RCC StructuresIrregular RC StructuresDynamicanalysisResponse spectrum methodObjectives: The current study intended to compare the geometry and locationof shear walls on regular and irregular structures. Method: Using the softwareResponse Spectrum method in ETABS, the dynamic parameters of irregular andregular...
The results were tabulated by performing Response spectrum analysis using ETABS version 9.7.4 in the form of maximum storey displacements, base shear reactions, mode shapes and storey drifts. Effect of Irregularity was studied by creating openings in shear wall and by varying the thickness of Shear...
ETABS has a table result named "story accelerations" and another "diaphragm accelerations", but not sure about what kind of acceleration those are: relative or absolute. Also, these tables are available only for a Response Espectrum analysis. Any suggestions would be so helpful. Greetings, Not...
