Experimental Research Of Lateral Resistence To Lattice Angle Column Wall Covered With Foamed Concrete

Conventional light gauge steel keel structure hasn’t gained its popularity in China because of its high cost, empty sense of touch, inconvenience of second decorations, by contrast, this style of structure is popular in low-rise and multi-storey housings of Europe and America.This dissertation introduces a new type of light steel keel wall structure: steel frames constituted of steel tube and latticed angle steel columns, casted by foamed concrete and thus a new type of composite wall composed of steel frame and foamed concrete is formed. This new sort of light gauge keel steel structure system has effectively overcome the shortcomings of traditional light steel structure:improve the massiveness degree of structure and won’t affect the following decoration of it.This dissertation aims at experimental research and static non-linear PUSHOVER analysis of two walls—AW1808 and AW3018, whose angle steel thicknesses are 0.8mm and 1.8mm, and with dimensions of 1800×3000mm and 3000×3000mm,respectively.Specific content see below:(1) Review of the development history of traditional light gauge steel keel structure. Introduction of the manufacture procedure of the composite wall.(2) Details of the test method, including the manufacture, installation, conservation, experiment of test specimen. Lateral resistance test of walls and material test of foamed concrete and steel are within the experiment.(3) Obtainment of the Load-Displacement and Load-Strain curve of the specimen according to the experiment data. Conclusions from the experiment.(4) Introductions of the FEM modeling method of the walls, ABAQUS analyses of the walls and the obtainment of the Load-Displacement curve and the stress contour.(5) By comparison between the experimental results and FEM analysis of the walls, conclusions can be drawn that load capacity of the walls and simplified models consist with each other, lateral displacement of the walls are extraordinarily affected by the prime crack. Differences between the test results and FEM analysis results are due to the incapacity of simplified model to concern the crack development of walls...
