Analysis of the Seismic Records of a Suspension Bridge
A well-instrumented suspension bridge in Los Angeles, was shaken by the October 1, 1987 Whittier earthquake (ML = 5.9). This study addresses the...
A Galerkin Method for the Convection?Diffusion Equation Using Asymmetric Weighting Functions
A variation of the Petrov-Galerkin method of solution of a partial differential equation is presented in which the weight function applied to the time derivative term of a one-dimensional...
Keeping Cables Calm
Cable vibration and corrosion are potential problems relating to cable-stayed bridges. Nonetheless, owners think their structural elegance is worth it, and increasingly longer cable-stayed...
An Alternative Analysis of Vibration Tests on Two Pile Group Foundations
Published quick-release horizontal vibration tests on two pile group foundations supporting large transformer banks are analyzed in this paper using the dynamic impedance approach embodied...
Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
Responses of Bilinear and Impacting Systems Subjected to Regular Waves
The dynamic responses of bilinear and impacting oscillators subjected to harmonic loadings are investigated. Differing from previous studies in which bifurcation diagrams were developed...
Modal Coupling Effect of Non-Classically Damping
The equations of motion of a structure in undamped modal coordinates may have non-zero off-diagonal terms in the damping matrix. Although these terms are commonly neglected, studies have...
Resonant Column Testing of Dynamic Rock Properties
Critical parameters for geophysical wave propagation studies are the dynamic elastic properties (shear and Young's moduli, and Poisson's ratio) and the intrinsic material damping of rocks....
Applications of Viscoelastic Damper to Jointed Structures for Seismic Mitigation
Some structures, such as dams, are built with contraction joints that might carry some small tensile stresses. Such joints are expected to open and close during an earthquake. That will...
Interaction Effects in the Hybrid Control of Euler-Bernoulli Beams
The effect of viscous and Voigt damping upon the open loop response of simple continua such as Euler-Bernoulli beams is well understood. However, when attempting to control a distributed...
Response of Secondary Systems to Short Duration Stochastic Input
Techniques have been developed for evaluating the mean-square response of systems to non-stationary loads. To gain insight into the response behavior, approximate expressions have been...
Stiffness and Damping Coefficients of Foundations
Parametric Excitation of Collapsible Latex Tubes
In 1985, Liu and Ding (1989) made an experiment of collapsible tubes containing a pulsatile flow. A latex tube is sealed up in a plexiglass chamber. If the transmural pressure (TP) of...
Synthesis of Lateral Structural Bracing with Active Tendons
The idea of combining X bracing, viscoelastic dampers, and active tendons in a structure which has been optimized for gravity loads is presented. It is shown that reduction of the structure's...
Response of Nonclassically Damped MDOF Systems to Nonstationary Random Excitation
A procedure for calculating the dynamic response of a nonclassically damped multi-degree-of-freedom (MDOF) system to nonstationary non-white vector-valued random excitation is developed...
A Damping Model for the Vibration of Nonlinear Laminated Composite Cylindrical Panels with High Order Transverse Shears
The damping characteristics of nonlinear vibration of a cylindrical panel including large displacements/rotations and parabolic transverse shears has been discussed in this study. The...
Effect of the Earth Rotation on Tide Induced Sediment Transport
Semi-enclosed seas are generally composed of narrow straits and wide basins, forming a strait-basin system. In the strait-basin system where tidal current prevails, the strong tidal current...
