Research On Bearing Capacity Of S. R. C Asymmetrical Cross-Shaped Columns

Based on the experimental study of 3 S.R.C members with asymmetrical cross-shaped section and 1 R.C member with asymmetrical cross—shaped section subjected to biaxial eccentric loading, this paper reveals the action behavior, failure patterns and bearing capacity of the S.R.C members with asymmetrical cross-shaped, examines the hypothesis of plane cross-section of average strain and preliminary obtains the general variation regularity of failure of asymmetrical cross-shaped section S.R.C members. On the basis of above mentioned research works, the computer programs of calculation of M-N interaction curve and M_x - M_y interaction curve arecompiled by using numerical iterative method. With this program, we can calculate ultimate strength of steel truss S.R.C columns with asymmetric cross-shaped cross-section, the comparison between theoretical results and experimental results shows satisfactory agreement. Furthermore, this paper also compares the bearing capacity between R.C columns and S.R.C columns, those columns have the same cross-shape and material, the result shows that the bearing capacity of S.R.C columns which depose a few section steel can be...
