Prediction model for compressive arch action capacity of RC frame structures under column removal scenario using gene expression programming

Structures, 2020
Abstract Compressive arch action (CAA) is one of the important resistance mechanisms against progressive collapse in reinforced concrete (RC) frame buildings at small deformations. In this study, the distinguishing features of Gene Expression Programming (GEP) are utilized in order to establish a prediction model for the CAA capacity of RC beam ...

An analytical model on compressive arch action capacity of 3D beam-column sub-assemblages under failure of one or two adjacent interior columns

Engineering Failure Analysis, 2020
Abstract Compressive arch action (CAA) is a desired load-bearing mechanism to mitigate the progressive collapse risk of commonly designed reinforced concrete (RC) frames. Thus, there have been number of studies concentrated on the behavior of in-plane beam-column sub-assemblages under a single column removal scenario.

Machine learning‐based resistance prediction model for compressive arch action in concrete beam–column substructures

Structural Concrete
Abstract With the rapid development and application of machine learning techniques, the use of proper intelligent algorithms to investigate the progressive collapse resistance of concrete frame structures has become significant. In this paper, a comprehensive database of 134 experimentally tested one‐way beam–column subassemblies was ...
