RISFour‐Spring Element for Cyclic Response of R/C Columns
Publisher: American Society of Civil Engineers
Abstract: The cyclic response of reinforced concrete columns subjected to bending and axial load is determined using a hysteretic element consisting of four axial springs. The spring sections consist of steel for tensile forces but ...
Response and Design of R/C One-Way Pier Hinges in Strong Direction
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental and analytical evaluation of one-way reinforced-concrete pier hinges subjected to a combination of axial compression, shear, and moment in the strong direction. Thirty-four ...
Fatigue-Life Prediction of Corroded Steel Bar Based on Fractal Theory
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study that sought to characterize the effect of corrosion and fatigue load on the behavior of reinforcing steel bars. The surface profiles of corroded steel bars and the relationship ...
Experimental and Simulation Study on the Response Characteristics of Engine Blades Under Thermo-Acoustic-Vibration Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal, acoustic, and vibration loads are important to affect the strength and durability of many aerospace products, especially the compressor blades, solar wings, antennas, etc. In extreme cases, a strong acoustic load ...
