Shaking table test of dynamic interaction of soil – high-rise buildings
Two sets of shaking table tests for comparative analysis were first designed and conducted to investigate the laws of dynamic interaction between soil and multiple high-rise buildings. The first set involves only a single high-rise building, and the second set includes a building group. Numerical results of the finite element models, using the Davidenkov foundation model regarding the dynamic non-linearity of soil, are presented and compared with experimental records. Experimental results show that the acceleration responses of structures in the case of multiple high-rise buildings are less than the response in the case of a single structure. The effect of the dynamic interaction between soil and multiple structures on acceleration responses is more obvious for short-period structures than those with long periods under EL Centro excitation. However, the motions of the long period structures in the two tests are almost the same. Opposite phenomena occur under the Shanghai man-made wave excitation. Moreover, the influence on the superstructure displacement is more obvious for long-period structures. The structure displacement in the case of multiple structures is larger than that in the case of a single structure under small earthquake excitations, but it is the opposite under strong earthquake excitations.
