Abstract

The chapter presents a three-dimensional (3D) finite element methodology to predict the behavior of high-strength angle bolted steel beam-column connections. Non linear 3D continuum elements are used for all parts of the connection with both ordinary steel and high-strength steel. A finite element model with three-dimensional shell and solid elements is established to investigate the structural performance of bolted connections between mild carbon steel and high-strength steel. The analysis results of the moment-rotation relationship and behavior characteristic of the connection with mild carbon steel and high-strength steel are compared and discussed in the chapter. It is found that stress-strain curve is very important parameter for accurate prediction of angle bolted connection behavior with high-strength steel.
