000015801 520__ $$2eng$$aIn recent years several benchmarking experiments and associated studies were launched to address the complex issue of multi-directional seismic loading on reinforced concrete nuclear and conventional structures with the objective of (a) understanding the overall complex structural response when structural elements go beyond yield and (b) testing the ability of advanced computational methods to capture the anticipated highly non-linear response. In addition and through specially designed laboratory tests of scaled structures, also accompanied by numerical predictions, the differentiation in the response of RC structures to near-field (NFE) and far-field type (FFE) earthquakes has been explored and studied. Presented in this paper are elements of two international benchmarking studies consisting of shake table tests of RC shear walls and three-dimensional structures designed to enhance torsional effects as well as numerical modeling and analysis employed to predict and qualify the structural response to NFE, FFE and multi-directional seismic loading in the non-linear domain. Specifically, advanced treatment of RC response and failure within the DYNA software along with precise structural modeling capabilities, provided the means of capturing the non-linear structural response and damage and comparing it with the scaled shake table test results. The key findings from both benchmarking studies and the performance of the numerical model employed to predict the experimental results will be presented. In addition, elements of a vulnerability study built around these shake table tests and the generation of seismic fragility curves will be discussed. Further, the ability of the computational model in capturing high strain rate effects and the dynamic response of RC structures will be discussed and benchmarked results associated with field experiments will be presents.
