Shaking table tests of RC frame structure across the earth fissure under earthquake

Abstract

showed that the performance of the soil-structure system was influenced by the frequency and amplitude of the input motion and the soil nonlinear behavior. Chen et al. [32] conducted a series of shaking table tests to investigate the effect of pulse-like ground motion on a multistory subway station.The testing results indicated that the pulse-like ground motion increased the dynamic responses of the subway station and the surrounding soils mainly due to its inherent rich low-frequency component and high energy absorption. However, on the basis of the author's knowledge, no research was found in the literature on shaking table test of RC frame structure across the earth fissure considering soil-structure interaction.In this paper, a series of shaking table tests were conducted aimed at understanding the seismic response of RC frame structure across the earth fissure. The earth fissure considered in this paper was referred to the earth fissure of Northwestern University-Northwestern Polytechnical University (f 4 ). The seismic performance of the RC frame structure under three earthquake motion records was evaluated and compared. 2 | EXPERIMENTAL PROGRAM 2.1 | Characteristics of the shaking table The shaking table tests were carried out at the Key Laboratory of Structure and Earthquake Resistance in Civil Engineering, Xi'an University of Architecture and Technology. The shaking table has an area of 4 m × 4 m and can produce three-dimensional, six-degree-of-freedom motions.FIGURE 2 The crack of the City Wall, Xi'an FIGURE 1 The crack of Tang Yan Road, Xi'an 2 of 15 XIONG ET AL.

“…The interaction of these effects complicates the stress state of the structure across the earth fissure . The structural response caused by the vibration and the settlement could strengthen each other or weaken mutually.…”
