A Computational Analysis of Dynamic Interaction of Dam with Reservoir Water and Sediment
A two-dimensional model of porous media is employed to calculate the reduction of the onset hydrodynamic pressure with the bulk modulus of pore water in reservoir sediment. However, the...

Application of the Generalized Channel Routing Model
Using the linear full dynamic finite difference model the applicability of diffusion and kinematic wave models is investigated. Two dimensionless numbers are suggested for applicable range...

Comparison of Flush and Chamber Mounted Dynamic Pressure Transducer
Modeling of hydraulic structures often includes the measurement of dynamic pressure fluctuations. The accuracy of the pressure measurements depends upon the geometry of the tap. Flush...

Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...

Shear Properties of Pultruded Glass FRP Materials
The in-plane shear modulus and the in-plane shear strength of a variety of pultruded glass fiber reinforced plastic (FRP) materials were measured experimentally in a pilot test program...

Limit State Analysis Correlated to a Full Scale Tower Test
A Limit State analysis technique has been developed for evaluating the structural capacity of lattice steel electrical transmission towers. The tower strength is determined by using a...

New Outlines for 500 kV Transmission Towers Using Cold-Formed Shapes: The Experimental Line of the American Electric Power Research Institute
The use of cold-formed steel members, in electrical transmission towers, is actually a feasible, reliable and economical solution. The EPRI experimental line is an example of the newest...

Floor Vibrations ? Tips for Designers
The purpose of this paper is to suggest a number of practical concepts which can be used to improve the performance of floor systems subject to occupant induced motion from either walking,...

Seismic Response of Flexibly-Connected Steel Frames
The response of typical low-rise steel building frames designed by the 'Type 2 Construction' method to moderate earthquakes is examined. Such frames are often...

Brace Connections for Ductility
Influence of connection design on the seismic behavior of welded bracing members made of double channels is studied in this paper. Shortcomings of commonly used connection details as per...

Hysteresis Studies Including Post Buckling of Angle Web-Members for Truss-Type Girders
The paper presents analytical studies of the buckling capacities and hysteresis behavior of angle-web members of truss-type girders. The eccentricity between the loading point and the...

Original Formulation of the Finite Element Method
Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members...

Numerical Methods for Solution of Finite Element Systems
A personal summary of solution methods for the static and dynamic analysis of finite element systems, which have been developed during the past 30 years, will be given. Numerical techniques...

Analysis of the Non-Planar Response of a Cantilever, with the Aid of Computerized Symbolic Manipulation
The nonlinear differential equations governing the static deformations of a cantilever with a tip mass are formulated and analyzed with the aid of computerized symbolic manipulation. The...

Optimal Location of Active Controllers Subjected to Seismic Excitation
In the application of structural control to seismic structures certain locations are advantageous for placement of the actuators. These locations reduce the structure's response...

Frequency Response Design of Controlled Structures
