This research analyzes the fracture experiment result of beam-to-column connections by dynamic loading in fracture mechanics. The analysis considered the influence of the plastic constraint and the rate of strain based on the CTOD design curve requested by the finite element method analysis. It was shown to be able to estimate the brittle fracture performance of beam-to-column connections by dynamic loading with the Charpy test result and the CTOD design curve. δ c estimated from the fracture displacement of beam-to-column connections corresponds to δ c converted from the Charpy impact test result of the bond line.
