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 ...
Development and Production of Ready-Mixed Soil Material
Publisher: American Society of Civil Engineers
Abstract: Ready-mixed soil material (RMSM) is a new range of soil material with physical properties lying between controlled low-strength material (CLSM) and soil cement. The design approach of RMSM combines the advantages of both ...
High-Strength Ecological Soil Materials
Publisher: American Society of Civil Engineers
Abstract: This study attempts to develop a recyclable, high strength, ecological soil material that does not consist of cement and is unpolluted, named high-strength ecological soil material (HSESM). The production of HSESM involves ...
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 ...
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 ...
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 ...
Wind-Induced Response Analysis for High-Rise Buildings Based on Time-Variant Speed Model Considering Climate Change
Publisher: American Society of Civil Engineers
Abstract: Under the scenario of global climate change, the wind resistance of high-rise buildings is facing a huge challenge. Climate change could cause an increase in wind speed, which poses a greater threat to high-rise buildings. ...
A Thermohydrodynamic Coupling Model of Oil Aeration Turbulent Lubrication for Journal Bearing With Interface Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Oil aeration lubricant in highspeed journal bearing is composed of mixture of continuous phase liquid and discrete phase bubbles. This work establishes a thermohydrodynamic (THD) coupling model for this lubrication condition. ...
