Out-of-plane Mechanical Performance Analysis Of Dryed-stack Panel

The infilled wall frame structure is a kind of widely used building structure system all over the world. The purpose of filler wall is just space-partitioning of and preservation of the building. The usefulness of frame is for bearing and supporting and resisting shear. Statistical earthquake data show that the infilled wall frame structure was easy to out-of-plane collapse in an earthquake.This is the reason why more and more scholars care about the safety problem of filler wall.With the development of the structure and material,a new type of filler wall which is call semi interlocking masonry (SIM) has drawn people's attention gradually. SIM panel has a huge contribution of in-plane energy dissipation and seismic mitigation for the structural system.it also can solve the contradiction between stiffness and energy consumption.Out-of-plane mechanical performance of SIM panel is also important. The paper make a special effort to investigate and study how the shape change of the block tenon impact the out-of-plane mechanical performance of the filler wall. This reseach of new blocks has significance of reference for the actual engineering application.For the purpose of bulid-in surface optimization, this paper carried out the following work:Based on finite element platform of Ansys, the finite element numerical simulation for the experiment which done by Totoev. and Zhiyu W. in the Newcastle university of Australia was established. Not noly a supplement for numerical simulation for the experiment was made, but also rationality had been proved for establishing the finite element model (FEM) and choosing material model. It ensured reliable parameter analysis for SIM plane with different build-in shapes and different build-in proportion. Based on FEM of Totoev's experiment, the FEM of SIM panel with different build-in shapes was established. The shapes were square, trapezoid, circular and catenary. It is concluded that the four kinds build-in shapes' advantages and disadvantages by analyzing how the shape change impact the out-of-plane mechanical performance of the filler wall, equivalent stress and fracture distribution of the filler wall. In addition, by establishing FEM of SIM panel with different built-in height and width and analyzing how the proportion change impact the out-of-plane mechanical performance of the filler wall, It is concluded the best build-in proportion. They were helped to reach the purpose of optimized built-in surface. Based on the formulation of the traditional filler wall's out-of-plane stability and simulate the out-of-plane stress of SIM panel with different high thickness ratio and masonry compression strength for verifying out-of-plane mechanical performance of SIM panel had the same as the traditional filler wall. The simulation also provided for the formulation of SIM panel's out-of-plane stability. The formulation of SIM panel's out-of-plane stability was proposed.
