Abstract:
The seismic responses of Beijing LG Building based on a calculating model in the general finite element software under vertical uniform excitation and travelling wave excitation were computed. The displacement and acceleration of the typical nodes at the top of the structure as well as the displacement, story displacement and internal force of the frame columns of two-towers were given, and compared with those under the excitation of uniform input. Then, the seismic response analysis of the structure under horizontal and vertical travelling wave excitation were carried out. The change rules of the respective physical variables of those nodes and frame columns under the traveling wave excitation were discussed. The results of horizontal and vertical seismic excitation were compared with those data produced under horizontal seismic excitation to analyze the role of vertical seismic to seismic response. The results show that traveling wave effect makes the seismic responses of the structure a great change.
