We report the results of experimental and numerical investigations of various pultruded I-beam and box section beam-to-column connections. The experimental results show the stiffness and strength developed by box section connections to be clearly superior to that of the I-beams.

We developed two simplified design models for composite frames with semi-rigid connections: an Euler beam model with variable connection parameters to account for joint flexibility, and a simplified finite element model.
