Effective Length Factor

The modified factor formulas, which are applicable to sway steel frames, are derived by considering joint relative rotational stiffness and adopting the modified stiffness factor. The finite element models of steel frames with semi-rigid and rigid connections are established using ANSYS program. Nonlinear finite element analysis of steel frames with two web and top-seat angles steel semi-rigid connections is conducted. Through bulking analysis of sway steel frames with semi-rigid connections, the effective length factor of sway steel frames is derived, which considers nonlinear rotation of two web and top-seat angles steel semi-rigid connections.

Experimental Researches

Beam-to-column connections affect the rigidity and strength of the overall precast concrete structures. Even though many experimental researches have been carried out on beam-to-column connections, the behavior and failure mode of the connection in precast concrete is often difficult to assess through experimental program. The finite element analysis, on the other hand, can be an option to properly evaluate the condition of the connections. Nevertheless, the finite element analysis on the beam-to-column connections is quite limited. Thus, there is a need to study and explore the behavior of the connection system based on the finite element data. In this research, the finite element analysis was performed to study the performance of different types of beam-to-column connections in precast concrete frames. A total of four specimens were modeled and analyzed to study the connection behavior involving load-displacement relationship under static incremental load. Different connection details were considered and the behavior of various beam-to-column connections were investigated.
