Simplified Modeling Strategies for non linear dynamic calculations of RC structural walls including Soil-Structure Interaction

This paper presents "blind" numerical calculations using multifiber beam elements, damage mechanics and plasticity constitutive laws. The calculations were performed in laboratory Sols Solides Structures-Risques (3S-R) in order to participate to two international benchmarks (NEES and SMART 2008) dealing with the non linear dynamic behavior of reinforced concrete structural walls tested on shaking tables. A numerical tool for simulating Soil-Structure Interaction (SSI) is also presented. The new element is based on the "macro element" concept and it is used to perform parametrical studies on the NEES structure considering different types of soils.
