装配式型钢斜交密肋复合墙受剪承载力研究

ompared with the traditional multi-ribbed composite wall, the precast shape steel oblique multi-ribbed composite wall is an innovative multi-ribbed composite wall with oblique frame-grid, whose reinforcing bars in the grids are replaced by shape steels. The improved wall possesses some advantages such as high lateral stiffness and bearing capacity, excellent seismic behavior and material savingStudy on the Shear Strength of Precast Shape Steel Oblique Multi-ribbed Composite Wall. On the basis of experimental research, shear strength of precast shape steel oblique multi-ribbed composite wall and the influence factors of shear strength of the new-type wall were studied through finite element simulation in the paper. The consequences showed that the results of numerical simulation was similar to that of experiment. There are many factors influencing shear strength of shape steel oblique multi-ribbed composite wall and section steel ratio is the leading one among them. The shear mechanism of shape steel oblique multi-ribbed composite wall was researched. Based on analysis results of the influence factors of shear strength, a formula for evaluating the shear bearing capacity of oblique section of shape steel oblique multi-ribbed composite wall under eccentric compression was put forward, meanwhile, the application conditions of the formula were proposed too. By comparing calculation of the shear bearing capacity formula with the value of test, it is receivable that the formula is reasonable and has a good applicability.
