RISClosure to “Efficient Prestressed Concrete-Steel Composite Girder for Medium-Span Bridges. I: System Description and Design” by Yaohua Deng and George Morcous
Publisher: American Society of Civil Engineers
Efficient Prestressed Concrete-Steel Composite Girder for Medium-Span Bridges. I: System Description and Design
Publisher: American Society of Civil Engineers
Abstract: A new prestressed concrete-steel composite (PCSC) girder system is developed to provide a viable alternative for steel and prestressed concrete I-girders in bridges. The PCSC girder is composed of a lightweight W-shaped ...
Efficient Prestressed Concrete-Steel Composite Girder for Medium-Span Bridges. II: Finite-Element Analysis and Experimental Investigation
Publisher: American Society of Civil Engineers
Abstract: In this paper, finite-element analysis (FEA) of the prestressed concrete-steel composite (PCSC) girder is performed to investigate strain and stress distributions in the girder sections and determine the influence of stud ...
Formation Mechanism and Characteristics of a Liquid Microlayer in Microchannel Boiling System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were performed using the laser extinction method to measure the thickness of the liquid film formed by growing flattened bubbles in a microchannel for gap sizes of 0.5 mm, 0.3 mm, ...
Lateral Live-Load Distribution of Dual-Lane Vehicles with Nonstandard Axle Configurations
Publisher: American Society of Civil Engineers
Abstract: The numbers and sizes of permitted vehicles that consist of at least four wheel lines have been increasingly crossing on highways and bridges. For safety purposes, it is necessary to understand how those truck loads are ...
Effective In-Plane Elastic Modulus of a Periodic Regular Hexagonal Honeycomb Core with Thick Walls
Publisher: American Society of Civil Engineers
Abstract: The effective in-plane elastic moduli of different types of honeycomb cores with thick walls are studied using analytical and numerical approaches. Analytical equations derived in this paper take a proposed jointed rectangle ...
Impact of Concrete Deck Removal on Horizontal Shear Capacity of Shear Connections

Discussion of “Bottom Aeration of Stepped Spillways” by Michael Pfister, Willi H. Hager, and Hans-Erwin Minor
Publisher: American Society of Civil Engineers
Thermal Hydraulic Performance of SiC Water and Al2O3 Water Nanofluids in the Minichannel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The singlephase flow and heat transfer behaviors of SiC and Al2O3 nanoparticles dispersed in water were studied experimentally in a multiport minichannel flat tube (MMFT). The volume concentrations of the two nanofluids ...
