INFLUENCE OF BEAM FLANGE THICKNESS ON SEISMIC PERFORMANCE OF FLANGE PLATE CONNECTIONS

This paper presents numerical studies on the cyclic behavior of flange plate connections. Nonlinear finite-element modeling is carried out in order to evaluate the effect of beam flange thickness on the seismic response of flange plate connections. The connections with thinner beam flange achieved the AISC seismic provision requirements; however the connection with thickest beam flange could not. Based upon the review is conduct in this paper, flange plate connection should not be classified as prequalified, and also it is recommended modifications for the design procedures.
