To predict the test results, a damage accumulation (DA) and a low cyclic fatigue (LCF) models, both based on strain responses, were incorporated to a fiber finite element model (FFEM2) demonstrating 1) that FFEM2 results were close to test measures, 2) that to meet performance based seismic design it is convenient to accumulate the damage induced by each record and remove the fibers that reached 100% DA by means of the LCF model. When DA and LCF models are not included in FFEM2, the major damages to be prevented, observed during tests, are not predicted. A practical solution to prevent failures by LCF, based on increasing the confinement of the concrete, is proposed.
