Abstract: The analysis of a degrading dynamic system is presented, and the damage-dependent response characteristics of the model structure are explored. Results from this study show that seismically induced

Abstract: Mechanical behavior of the Space Shuttle redesigned solid rocket motor (RSRM) propellant is studied from a phenomenological point of view. Motivated by the study of the experimental data three ...

Abstract: A detailed finite-element (FE) modeling procedure is presented for evaluating the redundancy of twin steel box-girder bridges. For this study, it was assumed that the passage of a truck live load triggers the sudden fracture ...

Abstract: The global poleward heat transport by the oceans tends to have a maximum in the vicinity of the Tropic circles. We have investigated the contribution of the Ekman flux to the heat transport in the Pacific and the Atlantic. ...

Abstract: Mechanical fasteners are used in composite structures to physically connect steel and concrete components. Composite action is developed primarily by transferring horizontal shear forces through dowel-type connections. ...

Abstract: This paper presents an investigation into the various factors which influence the peak average inside air temperature of outdoor telephone switching cabinets. The primary goal is to determine ...

Abstract: This paper investigates optimal tiltrotor flight trajectories and performance in vertical takeoff operations from a city-center heliport considering the possibility of one engine failure. A two-dimensional longitudinal ...

Abstract: In the aftermath of the September 11th tragedies, the vulnerability of the United States' transportation infrastructure to terrorist attack has gained national attention. In light of this vulnerability, various governmental ...

Abstract: In recent years, steel trapezoidal box girders for curved highway interchanges have become popular. For these bridge systems, significant steel girder cross-sectional stresses occur during the concrete casting sequence. ...

Abstract: Historical data show that terrorist attacks against transportation assets have increased in recent years and that the vast majority of these attacks have been bombings. As such, there is growing interest in protecting ...
