This paper introduces calculation of blot group connections supported eccentric shear force on the basis of ultimate strength theory,and compares with elastic-method through some examples .

Force analysis and calculation method of composite columns with core high-strength concrete filled steel tube under axial compression;

Research into reinforced concrete column with axial compression strengthened by carbon fiber clothes;

Introduction to the Japan CFST design method for axial compression members;

Study on eccentric compression of rapidwall with concrete filled every one or more holes;

Experimental study on deformation performance of median long columns with Yellow River silt cellular bricking structures subjected to eccentric compression;

Study of stress-strain relation of concrete filled steel tubular eccentric compression column;

Using the real stress\|strain relation of concrete material,a method to determine the ultimate load of concrete circular\|section column under eccentric pressure is discussed,and an ultimate load versus eccentricity curve is obtained.
