Analysis of progressive collapse process of RC structures based on hybrid framework of FEM-physics engine

Ruiran Li et al.

Summary: A hybrid numerical framework combining the finite element method (FEM) and the physics engine (PE) is developed for studying the full collapse process of structures. The accuracy of this framework is verified through collapse tests of different structures. Results show that the FEM-PE simulation can accurately capture nonlinear structure behavior and high-fidelity collapse.

Experimental and analytical studies on tensile behavior of kinked steel plates

Xing-Ju Yang et al.

Summary: In this study, a novel kinked steel plate configuration with large deformability was investigated for improving the progressive collapse resistance of frame structures without compromising their seismic performance. Tests and analytical modeling were conducted to understand the load-deformation properties and predict the equivalent stress-equivalent strain relationship of the kinked steel plates. The results showed that the relationship can be represented by a three-stage profile, and the steel plate thickness has an impact on the initial stiffness and ultimate strain of the kinked steel plates.

Simulation and analysis on improving progressive collapse resistance of RC assemblies by embedding locally debonded rebars near beam-ends

Xing-Ju Yang et al.

Summary: This paper investigates the load transfer mechanism and effectiveness of a novel method for improving the progressive collapse resistance of RC beam-column assemblies. The finite element models show that the bond-slip behavior of reinforcing steel bars significantly impacts the deformation and load-carrying capacities of the RC beam-column assemblies. The resistance improvement is achieved by fully mobilizing the catenary action and maintaining the flexural mechanism in the beams.
