Summary: In this study, a new reliability computation framework based on polynomial chaos expansion method is proposed and used to investigate the reliability of four typical configurations of reinforced concrete frame structures under progressive collapse. The analysis results provide the reliability and failure mode of the structures under different column-loss scenarios, and sensitivity analyses are conducted to explore the effect of uncertain parameters on the progressive collapse resistance.

Summary: This paper investigates the effect of novel structural detailing on the progressive collapse behavior of reinforced concrete frame structures. The role of masonry infill walls in the collapse mechanism of such structures is studied, and the modeling strategies are verified through previous experiments. The results show that the proposed structural detailing can effectively improve the progressive collapse performance of RC frame structures.

Summary: This study investigates the progressive collapse mechanisms of post-tensioned RC frames under column removal scenarios using the finite element method. The research shows that infill walls enhance the resisting capacity of post-tensioned frames against progressive collapse, but also change the failure modes and reduce the re-centering capacity.

Summary: This paper presents numerical simulations of multi-storey reinforced concrete frames under progressive collapse scenarios. The load resistance and failure mode of frames are obtained from the numerical simulation. Numerical results show that the single-storey frame can develop compressive arch action at the initial loading stage and subsequent catenary action at large deformations. However, in multi-storey frames, only the first-storey beam develops compressive arch action and catenary action, whereas beams in other storeys show rather limited axial compression force. Based on numerical results, a design method is proposed for multi-storey frames to resist progressive collapse, which has good accuracy in evaluating the collapse resistance.

Summary: A multilinear model was developed to evaluate the progressive collapse resistance of moment sub-frames after the removal of a penultimate column, and a parametric study was conducted. The analysis results showed that increasing the beam depth or beam top rebar ratio significantly increased the progressive collapse resistance.

Summary: This study evaluates the effects of using High-performance fiber-reinforced cementitious composites (HPFRCC) in beam-column joints on the behavior of reinforced concrete (RC) frame structures subjected to progressive collapse. The results show that using HPFRCC in beam-column joints can improve the robustness of RC frame buildings to progressive collapse by increasing beam-column joint stiffness, load-bearing capacity, and the ability to withstand deformations.

Summary: The effect of infill walls on the progressive collapse behavior of reinforced concrete frames is investigated, and it is found that the arrangement of integrity reinforcement can enhance the collapse resistance and suppress crack propagation in partial infill walls. A semi-analytical model is proposed to predict the load-bearing capacity of infilled frames after column loss using linear regression and gene expression programming techniques.

Summary: This study investigates the collapse resistance behavior of beam-column joints using dry connections. Results show that the strengthened top-seat angle connection improves resistance to beam flexural and compressive arch action (B-CAA), but reduces ductility. The presence of unbonded post-tensioning tendons significantly enhances the collapse resistance of the joints.

Summary: This paper develops an FE model using ABAQUS software to simulate the progressive collapse phenomenon of reinforced rubberized concrete frames. The numerical model is validated by comparing FEM results with experimental test observations, and further extended to include more models for a better understanding of progressive collapse. The simulation model achieved good results compared to the experimental results, meeting the resistance requirements of progressive collapse.

Summary: This study investigated the dynamic collapse responses of beam-column assemblies under a middle-column removal scenario through one static and four dynamic collapse experiments as well as numerical analyses. A new assessment procedure based on the energy-method was proposed and proved to be efficient and accurate. The research revealed that the dynamic collapse behaviors were influenced by the dynamic stress distribution characteristics and the material strain rate effect. The largest deformation of the assemblies was increased by both factors.

Summary: A rapid visual simulation method for predicting the collapse region in the progressive collapse of buildings was proposed. The method utilized affine transformation and modification script for modeling, built a machine learning model and a collapse propagation algorithm to predict the internal collapse region, and presented a visual simulation method based on Voronoi tessellation and physics engine to represent the collapse process. The accuracy and efficiency of the method were validated using real collapse event and finite element models, and the influence of Voronoi tessellation mesh size and different initial failures on the collapse scenario was discussed.
