The aim of this paper is a study on the seismic behaviour of a 4-storey moderately ductile Concentrically Braced Frame (CBF) building located on firm soil in Victoria, BC. The nonlinear analysis of the CBF building was carried out using the OpenSees framework and the investigated parameters were: interstorey drift, residual interstorey drift, and the type of failure mode. Nonlinear beam-column elements with spread plasticity and fiber cross-sections were used to model the behaviour of braces. In this simulation, the fracture of braces was considered by assigning the fatigue material model proposed by Uriz (2005). The building was subjected to both crustal and subdaction ground motions. The results show that braces experienced large demand at the ground floor level and developed large deformation in tension after the occurrence of buckling in compression.
