Experiment Study on Deformation Properties of Composite Shear Wall Combined with Cement Formwork and Concrete under Static Load

A structure type of composite shear wall is presented, the both sides of which are reinforced cement composite layer and the middle layer of which is concrete. In order to verify the cooperative work performance of cement-base composite layer and concrete, static load tests were carried out. In the test, the deformation properties of composite shear walls and the development law of the strain of concrete and steel were studied. Meanwhile, a normal shear wall with the same conditions was tested and the corresponding natures of two types of shear wall were contrasted and analyzed. The test results prove that the composite shear wall has a good overall deformation behavior, and can, to some extent, slow down the process of wall stiffness degradation. The research production has provided a foundation for the further exploration to the working properties of the composite shear wall under cyclic loading.
