STUDY OF PLANE FRAME OF SPRING ELEMENT WITH PROPERTY OF SEMI-RIGID JOINT

We deducted the stiffness equation of the beam element with spring joint and the plane frame of spring element with property of semi-rigid joint by using force method and the method of gradual rigidization. The method has the characterics of clear physical concept, simplicity of deduction processes. The beam element with spring joint and the plane frame of spring element were employed to calculating and analyzing bearing capacity in engineering structures with semi-rigid joints.
