A cross-platform approach for the seismic performance assessment of a shear critical rc frame

Improvements in computer-based structural analysis have made advanced nonlinear dynamic analysis of structures possible. However, the approach used should consider the fundamental behaviour of the structure under investigation, instead of arbitrarily trusting the results from any advanced software. To illustrate this, a seismic performance assessment was conducted on a shear-critical reinforced concrete frame tested by Duong et al. in 2006. A nonlinear finite element analysis using VecTor2, a program specializing in reinforced concrete structures loaded in shear, was used to inform a fiber model built using OpenSees, which is unable to consider shear behaviour. Nonlinear static and dynamic analyses were performed using the two models respectively. It was found that while both models arrived at similar results for the given seismic demand, the VecTor2 analysis demonstrated that not considering shear behaviour could lead to dangerous results for higher demand.
