In the ASCET Phase III, the goal was to assess and develop the Phase II (blind benchmark) recommendations using additional test results. The Phase III simulations were performed using a full set of the test results to calibrate numerical models, perform sensitivity studies and find governing parameters. In the ASCET Phase III benchmark, almost all participants, independently of the software used, calculated peak strength of the walls’ capacity to within a 10% difference of the measured values. However, similarly to the Phase II benchmark, the displacements and the shape of the hysteresis loops were more difficult to simulate.
