“…9 shows that the integral acceleration reduction coefficient is larger than 1 when the stiffness is small, and less than 1 when the stiffness is large, and 3000kN is the critical point of stiffness in this experiment. The interaction of soil and structure usually reduces the shear force of the structure at the bottom, but not all cases are the same [7,8], sometimes may increase the shear force. Fig.…”

In the conventional structure’s calculation and design, the rigid foundation assumption was often used in calculation of the dynamic properties and dynamic responses, while the actual situation is often very different. In this article, a steel frame model on the scale of 1/4 on the soil bin (no cover) indoor was excited to achieve the responses of structures with different stiffness. The responses were compared between the actual structure and the rigid foundation soil assumption structure simulated in the SAP2000 software. The results show that the stiffness of the upper structure has great effect on the acceleration, displacement and natural period of the structure when considering SSI.

Existing large‐scale electrohydraulic shaking tables (EHSTs) have limited frequency bandwidth because of the capacity of electrohydraulic systems. Here we propose a double‐layer shaking table (DLST) which is capable of generating excitations over a wide band of frequencies. The lower table is a conventional EHST with a long‐stroke actuator which can generate low‐frequency excitations. The upper table is fixed atop the lower table, and equipped with a short‐stroke actuator which can generate high‐frequency excitations. The FFT/IFFT signal separation process, three‐variable control algorithm, and feedforward compensation technique are employed to control the shaking table. The two tables are controlled simultaneously to ensure the upper table reproduces ground motions over a wide frequency bandwidth. A series of experiments were performed on a unidirectional DLST. The results suggest that the DLST can successfully reproduce excitations over a wide band of frequencies, and demonstrate that the proposed control methods are effective. The control procedure in which the upper table tracks the full‐frequency signal to compensate for the tracking errors of the lower table is recommended.

“…However, there is no specific design criteria and details for such bridges in current Chinese seismic design code. The effects of multi-support excitation [1][2], soil-structure interaction [3][4] and impact effect [5][6] on seismic responses of structures are focus in the field of earthquake engineering. Although lots of achievements of computation method and numercial simulation have been obtained, shaking table test for the continuous long span rigid-frame bridge with high pier is need for experimental verification.…”

To investigate the seismic response of long-span rigid frame bridges with high-pier, the shaking table test of a 1/10 scaled rigid frame bridge model is introduced in this paper. Details about test equipment, model design, test arrangement, input ground motion waves and test principle are provided. The response of bridge model under the seismic excitation included the uniform excitation and the multi-support excitation is observed. The influence of the soil-structure interaction on the bridge is considered through the real-time dynamic hybrid testing method. The impact effect for different ground motion input during the test is discussed. The influence of multi-support excitation, soil-structure interaction and impact effect on structural seismic responses are studied based on the test results. The isolation effectiveness and the damping effect are discussed as well.
