ABSTRACT
An analysis technique for Steel Frames that include Semi-Rigid connections is presented. The technique is easy to implement since it utilizes the stiffness method of analysis of structures. A typical beam element with six degrees of freedom(d.o.f.) is utilized together with a six d.o.f column element that utilizes stability functions to account for the P-Delta effect. The connection flexibility is incorporated into the model through a two d.o.f. spring element whose stiffness is the secant stiffness of the particular connection at the particular load level. Due to the non-linearity of the connection and the P-Delta effect the solution is iterative and the solution algorithm is presented.
