Hot-rolled Steel Combination Wall Shear Capacity Analysis

At present, the domestic and international for steel frame nodes and steel components on the mechanical properties of a wide range of research, and by the steel frame of elements of the wall of the overall force performance study less. Along with the steel structures in high-rise buildings, the author in the field of wide application attempts to establish a new wall-steel structure combination wall-steel frame unit, The mechanical properties of steel framework, failure mechanism for a comprehensive system analysis, not only has great theoretical significance and is of certain value for engineering application.In this paper, on the basis of documental materials, by using nonlinear finite element method for the steel structure of the new energy-saving murlal unit and three combination wall in the monotonous load bearing performance shear bearing studied systematically analyzed.This paper under horizontal direction drab loading method of the wall and the combination of wall unit on the shear bearing capacity of the full-scale numerical simulation, considering the material nonlinearity and the geometric nonlinear problem, use plastic shell element simulation wall components, wall frame columns and beams hinged connection between the way the bolt connection, wall body coupled approach, equation by ANSYS program automatic selection method. Nonlinear simulation results show that the distance increases, wall body bolts of shear capacity decreased; The width of the wall shear capacity increased significantly reduced, but not; Wall wall frame column spacing of encryption, the shear capacity increases; Wall panels materials greatly influenced the shear capacity, against the OSB panel for the shear capacity is plasterboard 1.65.Through research and analysis of new energy saving wall shear capacity, review of the wall after the deformation force, through the wall with opening size, bolt spacing, bearing capacity factors to analyze the impact of energy saving wall, andof pure shear capacity of frame structures were analyzed and summarized, for engineering practice to provide a good theoretical basis, and for future reference for the design of energy-saving wall.
