Flexible Membrane Wave Barrier
A linear analytical model is developed for the dynamic response of a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column...

Nonlinear Wave Runup on Large Circular Cylinders
Various design methods for computing nonlinear wave runup on a large-diameter circular cylinder are presented. First, empirical correlations are developed between the observed maximum...

Simulation of Nonlinear Wave Runup on Steep Impermeable Slopes
A numerical scheme is developed to simulate the propagation of second-order Stokes waves in a two-dimensional channel and the runup of these waves on an impermeable slope. The waves are...

Wave Exciting Forces on a Platform Fixed in Nonlinear Shallow Water Waves
This paper presents the result of an experimental observation of cnoidal waves and the nonlinear wave loads on a fixed barge in a 2-dimensional wave tank. The Ursell numbers of the waves...

Response Statistics of Tension Leg Platforms Under Wind Loads
This paper presents the direct integration method and Kac-Siegert technique to solve the first four cumulants in the general quadratic systems, and proposes the splitting technique to...

Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...

MINLP and MILP Strategies for Discrete Sizing Structural Optimization Problems
We address an important practical problem of optimum structural design in the presence of discrete sizing constraints. In addition, the topology of the structure may vary as well. The...

An Analysis Procedure for Cable Structures Using an Isoparametric Finite Element
The computer modeling and analysis of cable structures creates a major problem for the analyst in that the geometry of the cables is dependent on analysis results. The purpose of this...

Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...

A Comparison of Two Large Scale NLP Strategies for Determining Optimal Pump Station Controls
To solve the general nonlinear problem which is not simplified using the uniform spatial demand patterns, a two-level hierarchial scheme has been identified. The purpose of this decomposition...

Neurocomputing?State-of-the-art
Neurocomputing, an evolving discipline of science and technology which involves the study and use of nonlinear networks of parallel processing elements for certain classes of information...

Stochastic Response Analysis of Nonlinear Plane Trusses with Spatial Variability
This study considers responses of geometrically and materially nonlinear plane truss structures with spatially uncertain system parameters, subjected to random excitations. A stochastic...

Structural Response Statistics by Boundary Elements
In this paper a boundary element method for problems of random vibration of continuous structures is presented. The method reduces the effect of the mesh size on the accuracy of the results....

Explicit Integration Schemes in Structural Dynamics
Based on the recursive explicit form of Newmark ?-? method developed by Zienkiewicz for displacements, similar recursive expressions for velocities and accelerations are developed. General...

Limit and Post-Limit Behavior of Space Trusses
A numerical technique for the nonlinear analysis of space trusses taking into consideration such factors as load-eccentricity, initial crookedness of the member and nonlinear stress-strain...

Perplexing Issues in Concrete Softening
We explore some of the proposed techniques for modeling 'softening' via the constitutive model. We seek a framework which is both theoretically sound and physically...

Inelastic Mechanisms in Dynamically Loaded Ceramics
The dynamic response of ceramic materials has been the subject of intense research in the past decade. In this paper, we succinctly describe a plate impact experiment of a star-shaped...

Boundary Element Calculation of Nonlinear Wave Generation and Wave Current Interactions
A boundary element model is used to simulate the problem of nonlinear wave generation, and the interactions of wave and current. The numerical model is established based on the potential...

Stability of Nearly Breaking Long Waves
This paper addresses the development of equations for nonlinear dispersive waves that have improved stability properties over the commonly used Boussinesq-type equations. Boussinesq-type...

Evolution of Nonlinear Long Waves After Interacting with a Breakwater
Three-dimensional evolution of nonlinear long waves after interacting with a straight thin breakwater is investigated in this paper. The primary interest is to apply a weakly nonlinear...
