RISInteractive Buckling Behavior and Ultimate Load of I-Section Steel Columns
Publisher: American Society of Civil Engineers
Abstract: The paper is intended to present a numerical and experimental study on the local-overall interactive buckling behavior and ultimate load of I-section steel columns. The numerical method, named the finite strip plasticity ...
Site-Specific Extra-Heavy Truck Load Characteristics and Bridge Safety Assessment
Publisher: American Society of Civil Engineers
Abstract: Recently, the occurrence frequency of extra-heavy trucks (EHTs, gross weight ≥8 t) in China has significantly arisen due to the increasing demand of heavy freight transportation. Load characteristics, such as traveling ...
Vulnerability Evaluation of Villages Based on Social–Ecological Indicators and Strategies for Improvement: Case Study of Villages in the Northeast China Plain
Publisher: ASCE
Abstract: Given the background of rural revitalization, it is considered crucial for solving various village problems caused by fast urbanization, including the underuse of rural land resources and inappropriate spatial construction. ...
Numerical Investigation of Contaminant Oil in the Batch Transportation of Crude Oil and Diesel Oil with Different Out-Station Temperatures
Publisher: American Society of Civil Engineers
Abstract: Batch transportation of crude oil and refined products maximizes pipeline utilization and prevents long-term operation below economic throughput with reduced economic benefits. In this study, a numerical method that couples ...
Research on Silty Soil Capillary Water Rising in Yellow River Flooded Area of Eastern Henan
Publisher: American Society of Civil Engineers
Abstract: Numerical simulations and laboratory tests on soil samples with compaction degrees of 94%, 96%, and 98% are carried out to study the laws of capillary water rising and control techniques. The silty soil samples are obtained ...
Optimization of Closure Jacking Forces in Multispan Concrete Rigid-Frame Bridges
Publisher: American Society of Civil Engineers
Abstract: Creep, shrinkage, and temperature drops will shorten the main girder and create additional internal forces in the piers of continuous rigid-frame bridges. Horizontal jacking forces can be applied at the ends of a closure ...
Experimental Study on Characteristics of Separation Zone in Confluence Zones in Rivers
Publisher: American Society of Civil Engineers
Abstract: Confluence zones in rivers are common occurrences in natural rivers, and their flow structures have a great impact on sediment transport and pollutant dispersion in confluence regions. Previous studies mainly focused on ...
Effects of Solar Temperature Gradient on Long-Span Concrete Box Girder during Cantilever Construction
Publisher: American Society of Civil Engineers
Abstract: Three-dimensional (3D) finite-element analysis of a 106 × 200 × 106-m concrete box girder was conducted to study the effect of solar temperature gradients on long-span bridges during construction. Segments over the internal ...
