Progress in Hydromechanics
The historical development of hydromechanics in the fifty years since the founding of the Hydraulics Division is reviewed. Rouse's 1938 text, Fluid Mechanics for Hydraulic Engineers, provided...
Surface Water Hydrology
A brief history is presented of activities in surface water hydrology by the Hydraulics Division since 1938. Included is an historical review of division activities in such areas as precipitation...
Research in ASCE's Hydraulics Division
Research in the Hydraulics Division of ASCE during the last 50 years has undergone changes in both technical content and procedures. Open channel flow, sediment transport and pipe flow...
Cold Regions Hydrology and Hydraulics
The Cold Regions Hydrology and Hydraulics Monograph is the eighth in a series of monographs prepared by the ASCE Technical Council on Cold Regions Engineering. The book is intended to...
Water Jets Fight Silt
In the largest U.S. application to date, an array of hydraulic jets is being used to scour a ship berth at the Port of Grays Harbor on the coast of Washington. The system has been in place...
The Truck Commodity Survey in the New York-New Jersey Metropolitan Area
The Truck Commodity Survey was designed to gather information on the characteristics of truck traffic at toll barriers with minimal disruption to traffic flows. It was developed by the...
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
The installation of optimal control systems has been shown to be effective in reducing the vibration responses of structures. In addition to the effectiveness, there are many factors that...
A Family of Concurrent Algorithms for Transient Finite Element Solutions
We derive a family of methods for solving the equations of motion arising in structural dynamics which makes effective use of the architecture of concurrent computers. The algorithm is...
Neural Network Approaches in Structural Mechanics Computations
The neural computing paradigm has not been extensively researched in terms of its applicability to a wide variety of structural engineering problems. At an intellectual level this research...
