RISDesign of Cold-Formed Steel Built-Up Closed Sections with Intermediate Stiffeners
Publisher: American Society of Civil Engineers
Abstract: A series of column tests on cold-formed steel built-up closed sections with intermediate stiffeners is presented in this paper. The test specimens were first brake pressed from structural steel sheets to form open sections ...
Numerical Simulation of the Freezing Process of Concrete
Publisher: American Society of Civil Engineers
Abstract: Based on the equilibrium, continuity, and energy principles of multiphase porous media, a thermal-hydro-mechanical coupling model was developed for concrete upon freezing. To solve the governing differential equations, a ...
Behavior of High Strength Structural Steel at Elevated Temperatures
Publisher: American Society of Civil Engineers
Abstract: This paper presents the mechanical properties of high strength structural steel and mild structural steel at elevated temperatures. Mechanical properties of structural steel at elevated temperatures are important for fire ...
Experimental Investigation and Design of Concrete-Filled Steel Tubular CHS Connections
Publisher: American Society of Civil Engineers
Abstract: A series of tests on the concrete-filled tubular circular hollow section (CHS) connections is presented in this paper. Four types (T, Y, K, and KT) of 12 connections were tested. The tests covered two different chord wall ...
Compression Tests of Cold-Formed Steel C- and Z-Sections with Different Stiffeners
Publisher: American Society of Civil Engineers
Abstract: This paper describes an experimental investigation of stub column tests of cold-formed steel C- and Z-sections with different stiffeners. The experimental program consisted of 30 fixed-ended column tests of 6 series of ...

Turbulent Flow in a Rotating Two Pass Smooth Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser-Doppler anemometry has been applied to approximately 2-D turbulent air flow in a rotating 2 pass channel of square cross section. The axis of rotation is normal to the axis of the duct, ...
Analytical Solutions for Constant-Flux and Constant-Head Tests at a Finite-Diameter Well in a Wedge-Shaped Aquifer
Publisher: American Society of Civil Engineers
Abstract: Neglecting the effect of well radius may lead to a significant error in the predicted drawdown distribution near the pumping well area. New analytical solutions describing aquifer responses to a constant pumping or a ...
Aquifer Parameter Estimation for a Constant-Flux Test Performed in a Radial Two-Zone Aquifer
Publisher: American Society of Civil Engineers
Abstract: A patchy aquifer or an aquifer with a finite thickness skin can be considered as a radial two-zone aquifer system, which can be characterized by five parameters, i.e., the thickness of the first zone and four aquifer ...
Mutual Enhancement of Wind- and Tide-Induced Near-Inertial Internal Waves in Luzon Strait
Publisher: American Meteorological Society
Abstract: Tide-induced near-inertial internal waves (NIWs) are generated by tide–topography interaction and are energized by internal tides through triadic resonant interaction of internal waves. They are located above topography ...
