Finite Element Analysis of Beam-To-Column Joint In Steel Structure Subjected To Monotonic Load And Cyclic Load

Mechanical (CAD/CAM)

This paper is aimed to present a simple and accurate three-dimensional (3D) finite element model (FE) capable of simulating the actual behavior of beam-to-column joints in steel frames subjected to lateral loads. ANSYS is used to model the joint. The bolted extended-end-plate connection was chosen. It is important type of beam–column joints. The extended-end-plate connection is chosen for its complexity in the analysis and behavior due to the number of connection components and their inheritable non-linear behavior. Two experimental tests in the literature were chosen to verify the finite element model. And comparison of results of both the experimental and the proposed finite element carried out. One of these tests was monotonically loaded, while the second was cyclically loaded. In ANSYS instead of node-to-node contact element, surface-to-surface element is used as a contact element to enhance the model. The FE results show good correlation with the experimental one. An attempt to improve a new technique for modeling bolts is conducted. The results show that this technique is supposed to avoid the defects above, give much less elements number and less solution time than the other modeling techniques.
