High Rise

Reinforced concrete eccentric frame-shear wall structure has been widely used in engineering. However, this structure is mainly used for high-rise structure, and it is difficult to obtain accurate earthquake response of structure through experimental study. Therefore, simulation software needs to be used for study on seismic performance of high-rise structures. This paper produces useful conclusions for the project through shaking table test and the simulation of seismic performance provided by ANSYS finite element analysis software.

A reduced-scale model of 7-story reinforced concrete shear wall structure is made. Shaking-table test of the model is carried out. Two test conditions are considered. In the first condition, fixed base is used. In another condition, soil structure interaction is considered. According to the experimental results, the dynamic characteristic and seismic performance of shear wall structure is studied. The acceleration time history response of model structure is obtained. Based on the time-history response, the dynamic characteristics of model structure are studied by spectrum analysis. The Finite Element Model of actural structure is established by ANSYS. The dynamic characteristics and seismic performance of actural structure are studied. By comparing the experiment results and numerical analysis results under the fixed-base condition, the rationality of the ANSYS model and numerical analysis method of are verified.

This paper describes the dynamic damage test of a reinforced concrete (RC) wall structure with seismic isolation sysytem. It has been expected that seismically isolated structures are damaged in sudden when the accelerations of the structures exceed a certain level by hardening of the rubber bearings. However, the response behavior and the damage mode have not been observed by experimental test yet. So, shaking table tests were carried out at “E-Defense”, equipping the world’s largest shaking table, located at Miki City, Hyogo prefecture, Japan. The specimen was composed of an upper structure of 600 ton by weight and six lead-rubber bearings (LRBs) of 505 mm in diameter which provide both stiffness and hysteretic damping. The upper structure consisted of a RC mass and four RC walls with counter weight. The RC wall structure was designed so that the damage of the RC wall occurred between the shear force at the hardening of the rubber bearings and that at their breaking. The dimensions of the RC wall were 1600 × 800 × 100 mm (B × H × t). The reinforcement ratios were 2.46% in vertical by D13 (deformed reinforcing bar, 13 mm in diameter) and 1.0% in horizontal by D10. The shaking table test was conducted consecutively by increasing the levels up to 225% of tentative design earthquake motion. Consequently, because of the increase of the structural response by the hardening of the rubber bearings, the damage of the wall structure with seismic isolation system suddenly happened. In addition, the preliminary finite element analysis simulated the test results fairly well, which were the restoring force characteristics, the crack patterns of the RC wall structure and such.

Fbg Sensors

In this paper, FBG sensors are used to monitor and analyze the response of reinforced concrete frame-shear wall model in shaking table test in order to study the placement of sensors and the protection of the transmission lines. Based on the experiment data, the destructive mode and dynamic characteristics in earthquake are obtained through (by) analyzing the dynamic response of the structures. The experiment results show that using FBG is effective in monitoring the structures.

A new kind of RC frame-shear wall structures with partial columns sliding at upper ends is proposed in this paper. A shaking table test of this new kind of structure model (Model B) and a conventional frame shear-wall structure Model (Model A) were carried out, and the plan layout and the member size of the two models are nearly identical. The two models are 3-story and 2-bay by 2-bay, and the second story of either structure is weak story. The test results showed that: (1) under the same intense earthquake, the damage of Model B is slighter than that of Model A; and (2) under the same intense earthquake, the interstory drift angle, the acceleration and the shear force of weak story of Model B are reduced remarkably in comparison to Model A.
