To study the seismic behavior of short pier shear wall, 6 short pier shear wall specimens are tested under low cyclic loading with axial load ratio of 0.2. Hysteretic rules and stiffness degradation rate are determined base on test results and feature points are defined by theory, restoring force model that considers the effect of two loading direction to hysteretic characteristics is proposed based on test research, which could be applied to the nonlinear dynamic analysis of the structure.

Prefabricated shear walls have been widely used in engineering structures. Vertical connection joints of the walls are the key to ensure the safety of the structures. Steel–concrete composite structures have been proved to have a good bearing capacity and ductility. In this paper, a new type of prefabricated structure is proposed, in which vertical wall members are connected together through built-in steel sections and cast-in-place concrete. This paper studies the seismic performance of the proposed prefabricated concrete shear wall structure. Hysteretic curves and skeleton curves of the shear wall are obtained based on experimental analyses. A dimensionless skeleton curve model is developed using the theory of material mechanics and the method of regression analysis. A stiffness calculation method for different loading stages is obtained and a restoring force model is proposed. The proposed innovative prefabricated shear wall structure provides good resistance to seismic performance and the related analysis provides a fundamental reference for studies of prefabricated shear wall structures.

Seismic Behaviors

To evaluate the ductility and energy dissipation capacity of the beam with concrete-encased steel truss, eight specimens with different types of steel truss, reinforcement ratios, and shear span ratios were tested by low-cyclic loading regime. The results indicated that beams with concrete-encased steel truss performed plumped load–displacement hysteretic loops as well as high strength and stiffness. Moreover, cross-web members improved their seismic behavior more effectively than non-cross-web members. Finally, the restoring force model of concrete-encased steel truss beam is proposed in accordance with the experimental results, which can be used to predict the load–displacement behavior of concrete-encased steel truss beam. The results could also provide a reference for the design and application of concrete-encased steel truss beam in practice.

Dynamic load experiments of the disc-shaped metal rubber isolation component are performed. Through analyzing variation law of the parameters with amplitude and frequency, which are stiffness coefficient, damping coefficient and damping component factor, the hysteresis restoring force model which is able to fully reveal the dynamic characteristics of the component is established. The experimental verification results show that the theoretic calculations are consistent with the experimental data, which verifies the practicability and effectiveness of mathematical model and parameter identification. It has important practical significance for design of vibration isolation component with different requirements.

Based on the experiment of four models of reduced scale high-rise reinforced concrete wall under low-reversed cyclic loading, seismic behavior of reinforced concrete (RC) shear wall with diagonal web reinforcement under different ratio of axial compression is studied, in comparison to ordinary shear wall. The experiment result shows that diagonal bars affect the distribution of cracks and help to resist shear slip at the bottom of the wall. Seismic behavior of high-rise shear wall, which horizontal bars are replaced with the same amount diagonal bars in part can be obviously improved when the ratio of axial compression is high, but when the ratio of axial compression is low, the effect is not obvious.
