“…Another homogenization approach was used in paper [2], in which the authors, in turn, refer to work [3]. In these works, the substitute homogeneous material was used with increased tensile strength and with increased deformation modulus in comparison with the reference material (i.e.…”

“…Based on the review of existing literature, we can formulate the following conclusions: a great majority of studies concerning the modeling of the behavior of reinforced concrete buildings includes numerical analysis based on the heterogeneous material model, which is a composition of concrete and reinforcing steel together with the definition of cooperation between these materials [1,2,8]. No work on numerical analysis using the homogeneous model of substitute material presents a universal procedure for determining the static -strength -deformation parameters for such materials.…”

This paper outlines a method of determining the deformation and strength parameters for a hypothetical, homogeneous, substitute material which approximates the properties of heterogeneous materials in reinforced concrete elements. The model of the substitute material creates a concrete reference model, in which the staticstrength -deformation parameters were modified on the basis of the homogenizing function with the homogenization coefficient assumed as the effective reinforcement ratio of the reinforced concrete structural elements. The results of the comparative analysis of the numerical models using the hypothetical substitute material with experimental results for statically loaded beams and deep beams taken from the literature are presented.

“…Jayasooriya et al (2011) calibrated the results of linear elastic analysis and nonlinear elastoplastic analysis using an extracted 2-story frame structure of a 10-story building. The recent paper by Kelliher and Sutton-Swaby (2012) reported the results of a parametric study of blast load damage in a 10-story reinforced concrete (RC) office block. Kwasniewski (2010) conducted a parametric study on the progressive collapse of an eight-story, steel-framed structure using a sudden column removal method.…”

The advantage of using Autodyn, a specialized hydro-code for the analysis of explosion and impact, is its appropriateness for predicting the progressive collapse of a building when a column still has some load-bearing capacity left after a blast. However, the requirement of sharing nodes between volume elements for concrete and line elements for reinforcements hampers its application to the blast analysis of large-scale reinforced concrete structures. In this article, the blast analysis of a reinforced concrete frame structure is simulated using the reinforcement contact model in Autodyn. This modeling method shows structural behavior under blast load similar to that of a more precise model with reinforcement and concrete. Furthermore, this method allows for faster simulation of progressive collapse analysis for tall buildings. The effect of steel reinforcement patterns and spacing of stirrups in reinforced concrete beams is demonstrated by performing several progressive collapse analyses with the reinforcement contact model. Thus, the proposed modeling method can be effectively applied to the blast-loading progressive collapse analysis of a reinforced concrete frame structure.
