“…This elevation difference can affect the constraints imposed on the TG growth tendency as it cracks and its longitudinal bars yield. In order to study such effects, a detailed model of the structure is developed, in which, vertical rigid elements are used to account for the element elevation difference [ 26,27]. These rigid elements, which connect the slab elements to TG, are used to model slab centerline at a different elevation with respect to the TG centerline ( Fig.…”

“…Many experimental and numerical investigations have been conducted to explore the progressive collapse performance of RC structures. The numerical simulation method is very suitable for establishing a three-dimensional model of the whole structural system and for analyzing its mechanical behavior during the entire collapse process (Fu 2009, Kwasniewski 2010, Sagiroglu and Sasani 2013. On the other hand, the experimental study can truly demonstrate the local damage of components under large deformation and extract the effect of the deformation on the collapse resistance of structures.…”

To study the influence of slabs on the progressive collapse resistance of reinforced concrete (RC) frame structures, two 1:3 scaled substructures S1 (with slab) and B1 (without slab) were comprehensively tested. Both specimens had two spans, and each span had a length of 2 m. The width of the floor slab for S1 is 1 m for each side of the centerline frame beam. The two opposite sides of the specimens were completely fixed, and the remaining opposite sides were free. Two hydraulic jacks were applied at the top and bottom of the middle beam-column joint. At the beginning of the experiment, these two hydraulic jacks applied a pair of small balanced forces synchronously. Next, the bottom jack maintained the constant force, and at the same time, gradually increased the force of the top jack. Displacement controlled loading was used to simulate the failure of the middle column. By analyzing the load carrying capacities of S1 and B1, the influence of the slab on the progressive collapse resistance of the RC frame structures was discussed.

“…Analytical models of RC structures under extreme loading events typically rely on uniaxial stress‐strain laws, which may include limit strain definitions to account for rebar buckling and rupture and for concrete crushing . Such uniaxial laws can be combined with beam formulations having a fiber sectional model.…”

“…Although the aforementioned studies have used three‐dimensional FE analysis for simulation of structural components under cyclic loading, there are important aspects of behavior, such as rebar buckling and rupture, which have not been accounted for. Additionally, many studies have identified and described limitations of existing triaxial models for concrete . For example, the continuum models used by Faria et al and by Deaton cannot account for the development of irreversible (plastic) compressive strains in the concrete.…”

Summary This paper presents a three‐dimensional analysis framework, based on the explicit finite element method, for the simulation of reinforced concrete components under cyclic static and dynamic loading. A recently developed triaxial constitutive model for concrete is combined with a material model for reinforcing steel which can account for rupture due to low‐cycle fatigue. The reinforcing bars are represented with geometrically nonlinear beam elements to account for buckling of the reinforcement. The strain penetration effect is also accounted for in the models. The modeling scheme is used in a commercial finite element program and validated with the results of experimental static and dynamic tests on reinforced concrete columns and walls. The analyses are supplemented with a parametric study to investigate the impact of several modeling assumptions on the obtained results.
