Seismic Performance Evaluation of a Train Station Building Considering Earthquake-Induced Pounding Effects

Performance evaluation of adjacent buildings is generally performed by ignoring earthquake-induced pounding effects. Therefore, unexpected damages in adjacent buildings have occurred at the past earthquakes. The aim of this study is to evaluate seismic performance of a Train Station Building in Van during 2011 Van (Turkey) earthquake taking into account pounding effects. To this aim, three-dimensional pounding analyses of the Train Station Building are performed with SAP2000 structural analysis program. Nonlinear time history analysis of the building with and without pounding effects is conducted, and results are compared.In the Train Station Building consisting of three blocks, spaces among the blocks were not sufficient. The building had experienced damage in 2011 Van earthquake. Shear failures were observed over the walls in blocks. However, damages to column-beam joints were observed in the middle block. Thus, seismic performance of Block 2 is only evaluated by analyzing Train Station Building since any damage did not been observed in the structural elements of the other blocks. The results obtained from the analyses confirm that the experienced damages in the 2011 Van earthquake occurred due to the pounding effects.
