Study About Shear Strength And Ductility On Concrete Shear Wall With Permanent Shuttering Kit

The Dipy concrete shuttering kit technology is about the permanent formwork for concrete. Pouring the concrete into the formwork can form shear wall. While applied to outer wall ,one side of the formworks shall be covered by insulating layers ,with the performance of bearing loads and keeping warm .It has two forms we called I and II according to the difference of reinforcement bar .The buildings using this technology are predominant in the aspect of technology and economic returns. It complies with the policies on wall innovation and energy saving.The results of the research in and abroad has been summarized in this treatise .Then the ANSYS program is used to do simulation study on shear resistance capacity of concrete shear wall with permanent shuttering kit.First,A 3D finite element model is established to study the shear resistance capacity of shear wall. By comparing the analytical results with the test results about type I, it turns out that the model is reliable.Second, the research on type II using the same material with type I is executed. The results prove that it has better shear resistance capacity performance than type I.Third, the influencing factors of shear strength-- the concrete grade, the diameter of the reinforcement bar and the number of the sheet steel are discussed.Finally, some suggestions are proposed to improve the performance of concrete shear wall with permanent shuttering kit.
