Progressive collapse assessment of precast prestressed reinforced concrete beams using applied element method

Case Studies in Construction Materials, 2020
Due to the repetitive progressive collapse events, it became necessity to form theories of designs against those cases of loadings. Prestressed reinforced concrete elements become widely used in construction field due to various properties that ...

Progressive Collapse Performance of Prefabricated Step-Terrace Frame Structures in Mountain Cities

Applied Sciences
Because they have foundations with two or more different elevations, the mechanical performance of structures in mountain cities is significantly different from that of common structures.

Nonlinear analysis on progressive collapse of tall steel composite buildings

Case Studies in Construction Materials, 2018
Progressive collapse is defined as the expansion of an initial local failure of an element into another element of the structure and ultimately leading to the collapse of the whole structure or a large part of it in a disproportionate way.

Progressive Collapse of Bridges

Previously, history recorded several disproportionate collapse incidents around the globe like the collapse of the Tacoma bridge. The sudden collapse of bridges can have devastating consequences, resulting in significant loss of life and economic disruption.

Progressive Feedforward Collapse of ResNet Training

IEEE Transactions on Neural Networks and Learning Systems
Neural collapse (NC) is a simple and symmetric phenomenon for deep neural networks (DNNs) at the terminal phase of training, where the last-layer features collapse to their class means and form a simplex equiangular tight frame aligning with the classifier vectors. However, the relationship of the last-layer features to the data and intermediate layers

Risk−Based Cost−Benefit Optimization Design for Steel Frame Structures to Resist Progressive Collapse

Buildings
The design of structures to resist progressive collapse primarily focuses on enhancing structural safety and robustness. However, given the low probability of accidental events, such designs often lead to a negative cost–benefit. To address this problem,
