Abstract:
Based on the twin shear unified strength theory, considering the effects of local buckling of the square thin-walled steel tube and the multi-axial strength criterion for lightweight aggregate concrete, the calculation formulae of ultimate bearing capacity of short column of lightweight aggregate concrete filled square thin-walled steel tube were deduced, meanwhile, the influences of tension-compression strength ratio, material strength parameter, width-thickness ratio, as well as concrete strength on the ultimate bearing capacity were analyzed. Results show that the calculated results obtained in the paper agree well with test results from the references, and it can verify the rationality of the formulae. It can provide the theoretical basis for calculating the bearing capacity of short column of lightweight aggregate concrete filled square thin-walled steel tube, and this solution has an important practical value for engineering applications.
