Study On The Anti-shear Behavior Of Straw Concrete-the Thin-walled Steel Composite Wall

In recent years, with the rapid development of China’s infrastructure, neededa light weight, high strength, simple structure of new building materials Strawconcrete-a combination of cold-formed steel wall came into being at themoment.Straw concrete-a combination of cold-formed steel wall is a newcombination wall. Compared with ordinary concrete shear walls, which uses acold-formed steel welding or by way of self-tapping screw connections as wallskeleton, outsourcing straw concrete conservation through the factory to the highdegree of standardization, light weight, strength high construction speed, simplestructure, and has a superior performance in environmental protection, thermalinsulation, fire retardant, sound absorption areas.To promote this new wall paper conducted a theoretical analysis andexperimental study. The main contents are as follows:1,Our new wall of concrete needed for a trial with straw on the wall frame forprocessing in the laboratory for production and maintenance of the wall. Wemake a good pilot study of shear wall, the wall is applied to cyclic load, strainand displacement of its destruction recording characteristics of each measuringpoint and get the wall hysteresis curves, skeleton curves, ductility data indicators.2, We have established a large wall model in ABAQUS finite elementsoftware,the establishment of the constitutive parameters obtained in theexperiment straw concrete and thin-walled steel through the wall of themechanical properties calculated with the actual destruction of the wall were Incontrast, ABAQUS software to verify the accuracy of calculations.3, ABAQUS environment by changing the new wall shear span ratio, axialcompression ratio and form the skeleton of the structure of the wall, and inaccordance with the method of simulation of real experiment loading andboundary conditions, in order to compare the analysis of the wall in variousconditions different failure modes.
