RISBehavior of Hollow Tubular-Flange Girder Systems for Curved Bridges
Publisher: American Society of Civil Engineers
Abstract: This paper describes research results for an innovative curved highway bridge girder system, which uses I-shaped steel girders with hollow rectangular tubes as flanges. The increased torsional stiffness provided by the ...
Design of Horizontally Curved Steel Bridge Girders with Tubular Flanges
Publisher: American Society of Civil Engineers
Abstract: This study presents a practical approach for the design of horizontally curved steel I-shaped bridge girders with tubes as flanges [i.e., tubular flange girders (TFGs)]. Previous research has shown that the large torsional ...

Effects of Cyclic Intermediate Principal Stress on the Deformation of Saturated Clay
Publisher: American Society of Civil Engineers
Abstract: One-way cyclic loading induced by traffic loads will give rise to the cyclic variation of normal stress components of all three directions, including one vertical and two horizontal ones. The cyclic horizontal normal stress ...
Stability and Migration Characteristics of SDS and SiO2 Colloidal Gas Aphron and Its Removal Efficiency for Nitrobenzene-Contaminated Aquifers
Publisher: American Society of Civil Engineers
Abstract: The instability of colloidal gas aphrons (CGAs) in aquifers is one of the major obstacles influencing the remediation efficiency of CGAs-flushing. In this study, hydrophobic nano-SiO2 (HN-SiO2) was utilized to enhance the ...
Design Optimization for Structural-Acoustic Problems Using FEA-BEA With Adjoint Variable Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A noise-vibration-harshness (NVH) design optimization of a complex vehicle structure is presented using finite element and boundary element analyses. The steady-state dynamic behavior of the vehicle ...
