Research On Bearing Capacity Of S. R. C Inequiaxial L-Shaped Columns

Based on the experimental study of 3 S.R.C members with inequiaxial L—shaped cross-section subjected to axle compression and biaxial bending, this paper reveals the action behavior, failure patterns and bearing capacity of the S.R.C members with inequiaxial L—shaped, examines the hypothesis of plane cross-section of average strain and preliminary obtains the general variation regularity of failure of inequiaxial L—shaped cross-section S.R.C members. On the basis of above mentioned research works, with the computer program we can obtain M-N interaction curve and M_x -M_y interaction curve.With this program ,we can also calculate ultimate strength of S.R.C columns with inequiaxial L—shaped. The comparison between theoretical results and experimental results shows satisfactory agreement. Furthermore, this paper also compares the bearing capacity between the S.R.C columns of the large-diameter reinforcement and shaped steel for the cross-section and the S.R.C columns of the document, those columns have the same cross-shape and the location of loading point, the result shows that the bearing capacity of them has little difference . Finally, initial research above the practical...
