RISImproved Displacement-Based Timoshenko Beam Element with Enhanced Strains
Publisher: ASCE
Abstract: This paper presents an enhanced strain formulation for conventional displacement-based (DB) Timoshenko beam elements accounting for shear deformations. The proposed beam element is an extension of the original enhanced ...
Enriched Force-Based Frame Element with Evolutionary Plastic Hinge
Publisher: American Society of Civil Engineers
Abstract: This paper presents a novel enriched force-based formulation for beam-column elements. The enrichment was developed on the basis of the concept of evolutionary plastic hinges and incorporated with conventional force-based ...
Life-Cycle Performance Assessment of Aging Bridges Subjected to Tsunami Hazards
Publisher: ASCE
Abstract: Coastal reinforced concrete (RC) bridges have the potential to be subjected to tsunami hazards within their service life. On the other hand, the time-dependent chloride-induced corrosion will degrade the performance of the ...
Data-Driven Approach to Predict the Plastic Hinge Length of Reinforced Concrete Columns and Its Application
Publisher: ASCE
Abstract: Inelastic response of reinforced concrete columns to combined axial and flexural loading is characterized by plastic deformations localized in small regions, which are idealized as plastic hinges. Under extreme events such ...
Stochastic Analysis and Time-Dependent Reliability of Reinforced Concrete Beams Considering Spatially Distributed Corrosion Deterioration
Publisher: ASCE
Abstract: Reinforcement corrosion is an important part of durability research of concrete structures. The process of reinforcement corrosion is highly random due to various factors, and the effect of spatial distribution of reinforcement ...
Multilevel Damage Indicator–Enabled Seismic Damage Evolution Analysis and Fragility Assessment of Structures
Publisher: American Society of Civil Engineers
Abstract: The current performance-based seismic evaluation methodologies can be broadly classified into three categories based on the adopted indicators: displacement-based seismic evaluation, energy-based seismic evaluation, and ...
Interpretable XGBoost-SHAP Machine-Learning Model for Shear Strength Prediction of Squat RC Walls
Publisher: ASCE
Abstract: RC shear walls are commonly used as lateral load-resisting elements in seismic regions, and the estimation of their shear strengths can become simultaneously design-critical and complex when they have so-called squat ...
Embedding Prior Knowledge into Data-Driven Structural Performance Prediction to Extrapolate from Training Domains
Publisher: ASCE
Abstract: Machine learning (ML)–based data-driven approaches have become increasingly prevalent for predicting structural performance. Because a properly trained ML model can learn hidden patterns in databases of experimental samples, ...
Experimental and Numerical Investigation on Progressive Collapse Resistance of Post-Tensioned Precast Concrete Beam-Column Subassemblages
Publisher: ASCE
Abstract: In this paper, four 1/2 scaled precast concrete (PC) beam-column subassemblages with high-performance connection were tested under push-down loading procedure to study the load-resisting mechanism of PC frames subjected ...
Probabilistic Model Based on Bayesian Model Averaging for Predicting the Plastic Hinge Lengths of Reinforced Concrete Columns
Publisher: ASCE
Abstract: A probabilistic model is devised for predicting the plastic hinge lengths (PHLs) of RC columns. Seven existing parametric models are evaluated first using a comprehensive database comprising PHL measurements from 133 RC ...
