Abstract:
The lattice model provides equivalent continuum formulations for a variety of constitutive equations. In this study, the Compression Field Theory (1) developed by Vecchio and Collins is re-formulated in the form of an equivalent lattice model and developed further for cyclic loading, beyond the scope of the original model. The RC column experiments of UCSD (2) are then analyzed by the method, for which the equivalent lattice model shows acceptable agreement with the experiments. It is noted that shear failure during cyclic loading after yielding of the flexural reinforcement is captured by the method, which is a characteristic feature of this numerical simulation.
