Abstract
Adoption of precast concrete building systems is increasing, primarily due to reduced on-site construction times and enhanced quality control. However, inherent discontinuity at the joints of precast structures makes achievement of robustness challenging following sudden column loss. The paper uses a component-based NLFEA approach to investigate the effect of joint detailing on the robustness of a previously tested full scale precast concrete building. The analysis shows that flexure was the principal load resisting mechanism following various sudden column removal scenarios. Detailed parametric investigations show that the global structural response is significantly influenced by choices made in the modelling of the beam-column joints.
