RISCharacterization of Ultrahigh-Performance Concrete Materials for Application in Modular Construction
Publisher: ASCE
Abstract: In this paper, a new class of self-consolidating ultrahigh-performance concrete (UHPC) was investigated. The UHPC featured a compressive strength higher than 150 MPa with self-consolidating characteristics desirable ...
Two-Dimensional Finite-Element Simulation of Periodic Barriers
Publisher: ASCE
Abstract: A novel kind of seismic isolation technique called “Periodic Barriers,” which combines trench-type wave barriers and metamaterial, is introduced in this research. Metamaterial possesses a unique frequency-selective property ...
Finite-Element Simulation and Cost–Benefit Analysis of Full-Scale Skewed Inverted-T Bridge Caps with Traditional and Skew Reinforcements
Publisher: ASCE
Abstract: In highway design, inverted-T bridge caps (ITBCs) have been extensively used in the United States. Depending on the project requirements, some ITBCs need to be skewed. In Texas, the traditional method of flaring the ...
Numerical Simulation Study of the Optimal Parameters for Dust Reduction by an External Air Curtain (EAC) in Continuous Mining Tunnel
Publisher: ASCE
Abstract: Coal dust in continuous mining tunnels is extremely hazardous to drivers and other workers. In order to solve this problem, a continuous mining tunnel model is built based on computational fluid dynamics and gas–solid ...
Parametric Study on the Structural Behavior and Failure Mechanism of Skewed Inverted-T Bent Caps
Publisher: ASCE
Abstract: In the past several decades, the inverted-T bent caps (ITBCs) have been frequently used as an innovative type of bridge superstructure worldwide. In some specimens, the bent caps have to be skewed to meet the landscaping ...
