Wood-Cement Particleboard: Impact Behavior and Potential Application in Crash Barriers
Publisher: American Society of Civil Engineers
Abstract: The impact characteristics of wood-cement particleboard (WCPB) made with wood particles produced from the waste stream are investigated. With a view toward sustainable practices, the potential application of WCPB to enhance ...
Random Vibration under Propagating Excitation: Closed‐Form Solutions
Publisher: American Society of Civil Engineers
Abstract: Closed‐form solutions are presented for random vibration response integrals arising in the analysis of multi‐degree‐of‐freedom (MDOF) systems to stationary nodal and/or support excitations Any pair of excitations must ...
Correlation Analysis in Space‐Time Modeling of Strong Ground Motion
Publisher: American Society of Civil Engineers
Abstract: The estimation of frequency-dependent correlation functions for pairs of accelerograms is important in the analysis and modeling of the space-time variation of earthquake ground motions. Two methods of estimating the ...
Improved Repair of Concrete Structures Using Polymer Concrete Patch and FRP Overlay
Publisher: American Society of Civil Engineers
Abstract: Concrete structures that are damaged due to cracking and spalling, associated with corrosion of reinforcing bars, are often repaired using shallow depth surface patches. Cracking and full or partial delamination of the ...
Sensors to Monitor CFRP/Concrete Bond in Beams Using Electrochemical Impedance Spectroscopy
Publisher: American Society of Civil Engineers
Abstract: The use of inexpensive electrochemical impedance spectroscopy based sensor technology for nondestructive evaluation (NDE) of bond degradation between external carbon fiber-reinforced polymer (CFRP) reinforcement and concrete ...
Random Vibration of Laminated FRP Plates with Material Nonlinearity Using High-Order Shear Theory
Publisher: American Society of Civil Engineers
Abstract: The nonlinear response of laminated fiber reinforced plastic (FRP) plates modeled with finite elements and excited by stochastic loading is studied. FRPs are being used widely for structural applications in recent years ...
Response of Simple Beam to Spatially Varying Earthquake Excitation
Publisher: American Society of Civil Engineers
Abstract: It may be important to consider the effect of the spatial variation of strong ground motion when determining the dynamic response of spatially extended structures. In this paper an empirical space‐time earthquake ground ...
Closure to “<i>Eigenproperties of Nonclassically Damped MDOF Composite Systems</i>” by R. S. Harichandran and Yan Zhang (July, 1989, Vol. 115, No. 7)
Publisher: American Society of Civil Engineers
Eigenproperties of Classically Damped MDOF Composite Systems
Publisher: American Society of Civil Engineers
Abstract: A perturbation technique is employed to determine the eigenproperties of structural systems composed of multi‐degree‐of‐freedom (MDOF) primary and MDOF secondary systems. The eigenproperties of the individual subsystems ...
Eigenproperties of Nonclassically Damped MDOF Composite Systems
Publisher: American Society of Civil Engineers
Abstract: In composite systems made up of multi‐degree‐of‐freedom (MDOF) primary and MDOF secondary systems, the composite system is virtually always nonclassically damped, even if the individual subsystems are classically damped. ...
