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.

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.

Time History Response

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.

The New Period

In order to respond to the construction policy of "economy, application, green and beauty" put forward by China in the new period, the assembly structure has gradually become the focus of attention in recent years. Compared with the traditional cast-in-place structure, the assembled structure is more in line with the requirements of energy-saving, material-saving, environmental protection, etc. Therefore, it is of great importance to further study the seismic performance of assembled structures. However, existing assembled shear wall structures often suffer from problems such as the joint position is difficult to construct because of its wet work, and strong component weak nodes often appear. The seismic performance of the joints needs to be further studied and so on. Aiming to solve above problems, a new type of pre-stressed constraint assembled shear wall structure was proposed by us. The structure is connected by pre-stressed tendon to shear wall, and there is no wet operation at the construction site, which is conductive to improving construction quality. When the earthquake occurs, the structure can increase its self-shock period by changing its own stiffness, so as to reduce the earthquake stress. Meanwhile, many conditions to improve the ductility of the structure do not need to be considered, thus avoid the waste of steel materials. Based on the time history analysis of cast-in-place shear wall structure model and pre-stressed shear wall structure model, the results of calculation show that: compared with cast-in-place shear wall structure, the pre-stressed shear wall structure can effectively reduce the earthquake effect by about 90%.

The cyclic tests of three one-storey spatial RC frame-shear wall structures with slabs were conducted to investigate the failure modes and the base shear-floor displacement hysteretic responses of the model structures. Then three dimensional numerical simulations were performed using the finite element program ABAQUS/Standard and ABAQUS/Explicit. The test results are detailed in this paper and compared to those of the numerical simulations. It is shown that: (a) plastic hinges initiated at the bottom of the shear wall and followed by forming near the upper ends of columns, resulting in wall-column hinges side-sway failure mechanism; (b) to a certain extent, the horizontal force bearing capacity of the structure increases with the increasing of the vertical load; (c) it is verified that the pushover results of both ABAQUS/Standard and ABAQUS/Explicit solutions agree well with the test results in the case that the parameters are reasonably chosen.
