Damage Evaluation of Beam-Ends in Braced Steel Moment Frames Taking Member Fractures Into Account
Abstract eng: Recently, there have been concerns of the risk of fracture at the beam-ends of existing steel building frames during the long period and long duration motion of the Nankai-trough great earthquake, which is expected in the near future. Researchers have proposed several simple evaluation methods to estimate cumulative damage from maximum ductility demand, avoiding the need for time history analysis. In this paper, cumulative damage at the beam-ends of a high rise steel building during long period and long duration motions is evaluated taking brace fracture into account. A simple damage evaluation method is proposed based on the event velocity and energy spectrum.
