Experimental study on shear resistance performance of concrete filled steel tube shear block stub columns
摘要
Abstract
Based on the experimental study on the shear resistance performance of concrete filled steel tube shear block stub columns with square or circular section,the shear resistance performance under monotonic load and cycle load were studied,and the load-displacement curves,load-displacement hysteretic loops and the skeleton curves of two different section forms concrete filled steel ultra short columns without axial force were obtained.With the finite element method,numerical simulation of the experiment was carried out.The reasonable selection of constitutive relations of materials and failure mode made the theoretical calculation correspond to experimental results,as a result,the relative error of ultimate load is under 8.84%.The experiment result turns out that the concrete filled steel tube shear blocks have good shear resistance performance.Under monotonic load,the relative deformation of the shear block with square or circular section both are over 4.0%.Under the cyclic load,the hysteretic loops of the concrete filled steel tube shear blocks with circular sections are plumber,both the ductility factor and the energy dissipation value are better than the concrete filled steel tube shear blocks with square section.It also turns out that the theoretical analysis are reliable.关键词
