ABSTRACT

The tensile resistance of the main plate of a bolted connection is reduced by making bolt holes. The structures are sometimes exposed to excessive forces, such as earthquake action. The resistance and energy absorption are important performances against such forces. High energy absorption can realize a ductile structure. However, the energy absorption of the bolted connection needs to be clearer because the bolted connection is usually designed based on resistance. In this study, the energy absorption of bolted connections was investigated by a finite element analysis. At first, the numerical model was checked by reproduction analysis of some experiments focused on failure modes and the stress-strain model. A parametric study was conducted to clear the energy absorption. The energy absorption was evaluated and discussed, focusing on the failure modes.
