Abstract
Structural analysis of frames is generally based on centreline-to-centreline geometry. However in many structures, member dimensions might be quite large and have a significant effect on frame lateral stiffness. Rigid offsets extending from the joint centrelines to the faces of the members are used to model the rigid rotation kinematic of finite joint area. This approach can underestimate drifts of structures since it neglects elastic deformations of the joint regions. In this paper, a joint element is used to consider the rigid kinematic motion, elastic shear, and bending deformations of beam-column panel zone regions. Parametric analyses have been carried out on the seismic response of a ten-storey steel frame to determine the impact of panel zone deformations on the structure's elastic response. It is shown that kinematic effects and panel zone shear deformations are best modelled using rigid zone reduction factors to define rigid offset effective lengths. On the other hand, the consideration of panel zone bending deformations resulted in drifts values that were significantly larger than the usual rigid point joint assumption.
