| This paper describes two practical methodologies for modeling the collapse of reinforced concrete structures.They are validated with a real scale test of a two-floor structure which loses a bearing column. The objective is to achieve accurate simulations of collapse phenomena withmoderate computational cost. Explicit finite elementmodels are used with Lagrangianmeshes,modeling concrete, and steel in a segregated manner. The first model uses 3D continuum finite elements for concrete and beams for steel bars, connected for displacement compatibility using a penalty method. The second model uses structural finite elements, shells for concrete, and beams for steel, connected in common nodes with an eccentricity formulation. Both are capable of simulating correctly the global behavior of the structural collapse.The continuum finite element model is more accurate for interpreting local failure but has an excessive computational cost for a complete building.The structural finite elementmodel proposed has amoderate computational cost, yields sufficiently accurate results, and as a result is the recommended methodology. | |
