“…A concrete shear wall system that provides sufficient lateral strength, stiffness, and deformation capacity to resist strong ground shaking is mainly used in medium-or high-rise buildings [1,2] . With the acceleration of urbanization, traditional multistory masonry structures are gradually replaced by low-and medium-rise concrete shear wall structures in rural areas in China [3] . Compared with the conventional concrete shear wall structure, the precast concrete shear wall structure shows advantages of rapid construction, lower cost, and pollution reduction [4][5][6] , which is appropriate for low-rise residential buildings in rural areas.…”

This paper presented an innovative numerical modelling method for bolt-connected precast wall panels, and a three-dimensional finite element (FE) model based on a full-scale two-story bolt-connected precast concrete composite wall panel structure tested on a shake table was proposed for nonlinear dynamic analysis. The wall panels were schematized with multilayer shell elements, whereas all bolted joints were described with 3-DoF nonlinear springs. The mean error rates between the numerical and experimental results of translational periods, maximum lateral displacements, and maximum accelerations were 13.10%, 10.71%, and 8.31%, respectively, showing that the proposed FE model possessed the ability to capture global and local responses. Parametric studies were conducted based on the verified FE model to evaluate the effects of the design parameters, such as the column-to-column connection, size of window openings, and number of stories, on the seismic performance of the bolt-connected precast wall panels. In addition, a three-story structure with a window-to-wall ratio of 0.50 without connections between columns was modelled and loaded by high-intensity seismic excitation, which meets the plastic story drift limit of θu = 1/120 and shows good safety margins against earthquakes.

“…This is mainly due to the lower strength of RAC compared to ordinary concrete. Seismic performance tests of low, medium, and high shear walls of recycled coarse and fine aggregate concrete were performed by Cao and Zhang [19][20][21][22][23], showing that the bearing capacity, stiffness, ductility, and energy dissipation capacity of recycled coarse aggregate concrete shear walls are slightly worse than those of ordinary concrete shear walls. Again, with the increase of recycled aggregate replacement in the mixture, the bearing capacity and ductility of the recycled aggregate concrete shear wall decreases, although the seismic performance of the recycled concrete shear walls does meet the needs of structural design.…”

Abstract:Recycle Aggregate Concrete (RAC) is a common "green" product used for a variety of purposes, although the durability and strength of the material still need more research to adequately determine influences on these parameters. The failure pattern, punching bearing capacity, and deflection variation of wallboard of both ordinary concrete and RAC with various rebar reinforcement diameters and spacing were analyzed. Based on experimental data, the ABAQUS finite element analysis of the thin wallboard was performed, and the calculated results are in good agreement with the experimental results. The results show that the failure characteristics of ordinary concrete wallboards and RAC wallboards are similar, but the brittleness of the RAC specimens is more significant. Under the same reinforcement ratio, concrete material, whether new or recycled, had little effect on the punching bearing capacity of the specimens. In the case of a low reinforcement ratio, increasing the reinforcement ratio (decreasing the spacing of steel bars) can effectively improve the bearing capacity of the wallboard. Under the same reinforcement ratio, the wallboard with larger diameter and larger spacing has a higher bearing capacity and less deformation after failure.

The effective application of lightweight stay-in-place concrete forms for casting shear walls subjected to wind and seismic loading is of particular concern to practitioners. Insufficient technical data available for new kinds of wall systems, such as Polyvinyl Chloride (PVC) form walls, hinder their implementation in construction practice. To that end, an effective experimental and numerical campaign was launched at Western Sydney University to investigate the structural performance of PVC form walls when subjected to in-plane shear loading. A set of push-out specimens was designated to conduct monotonic in-plane shear tests until failure. All failure phenomena, capping strengths, and ductility capacities were monitored. Test results indicated that the embedded PVC latticed webs could efficiently protect the concrete web from sudden crushing and improve ductility capacity and failure pattern of the specimens. Nonlinear finite element analysis on test specimens was also conducted and good correlation with experiment results was achieved.
