Evaluation of the 9-Story Benchmark Building Shear Model
24 Jan 2012 | Computational Models | Contributor(s): Amin Maghareh, Matthew J. Barnes, Zhuoxiong Sun
In this model, the 9-strory benchmark FEM model is remodeled as a 9 degree of freedom shear building model. To evaluate the model the displacement, velocity and acceleration responses of the shear model are compared to those obtained using the FEM model (time history comparison and RMS response)....
