| Abstract: | In this paper some analysis is practiced on a real-world project,that is,the frame-core-tube structures.we establish the calculation model of the frame-core-tube structures using the finite element analysis software NOSACAD.The elasto-plastic time history analysis is carried out under the frequent and rare intensity of 7 degree earthquake.The seismic behavior,failure mechanism and cracking pattern are estimated basing on the experimental results,including natural frequencies,acceleration and displacement re... |
