TL;DR: In this article, a transferred stress system (TSS) on longitudinal reinforcement bars was developed for increasing the bending capacity of reinforced concrete (RC) elements. But, the authors did not evaluate the performance of the TSS fixed beam compared to the ordinary fixed beam.

TL;DR: The buckling analysis of rectangular sandwich plates with pure polymeric tapered cores and functionally graded carbon nanotube (FG-CNT) reinforced composite face sheets under static and harmonic dynamic loads is presented in this article.

TL;DR: In this article, the performance of column-tree moment connection (CTMC) under fire and static loads was analyzed using nonlinear finite element simulations, and the results indicated that the rotation and deflection of the CTMC depend on the temperature.

TL;DR: In this article, a finite element (FE) model is developed for simulating the performance of reinforced concrete connections under post-earthquake fire (PEF), and surrogate models, including multiple linear regression, multiple natural logarithm (Ln) equation regression (MLnER), gene expression programming (GEP), and an ensemble model, are used to predict the remaining load-carrying capacity of an RCC under PEF.

TL;DR: In this article, the performance of reinforced concrete tunnel (RCT) under internal water pressure is evaluated by using nonlinear finite element analysis and surrogate models, including principal component regression (PCR), Multi Ln equation regression (MLnER), and gene expression programming (GEP) for predicting the percentage of damaged surfaces (PDS), the effective tensile plastic strain (ETPS), the maximum deflection of the RCT, and the maximum deformation of crown of RCT.
