Effect of Fly Ash on the Microstructure and Durability of Concrete
The influence of fly ash on the microstructure and durability of concrete was investigated. It was found that the use of 50% fly ash in concrete reduced greatly its resistance to freezing-and-thawing...
Permeability Effects on the Sulfate Resistance of Concrete
A laboratory study was conducted to determine the effect of permeability on the sulfate resistance of concrete containing fly ash. Concrete specimens were moist cured for 7 and 100 days...
Significance of Yield Surface Corner-Like Effects in Inelastic Stability Solutions
This paper presents the author's experiences with finite element prediction of the inelastic stability of steel plate structures. The implications of linear versus nonlinear...

Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...
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...
An Overview of Structural Reliability Methods
Recent developments in structural reliability theory and better availability of load and strength data suggest that reliability-based design (RBD) methods should be considered as a practical...
Cambering of Steel Beams
Cold cambering with force in the fabrication shop is an effective and economical method of compensating for deflections of composite beams. Typical beams should be cambered for dead load...
Six Story Tubular Atrium
The author designed an atrium structure with two stair-stepped atriums placed at 45? to the tower 'Figueroa at Wilshire' in Los Angeles, California. This structure...
Cold-Formed Z-Sections Under Axial Load and Bending
The use of cold-formed Z-section members as beam-columns presents some unique design problems which are not adequately addressed in the current design specifications. If these members...
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...
Strength of Biaxially Crooked Jumbo Columns
The ultimate strength of axially loaded jumbo columns with biaxial initial out-of-straightnesses is analyzed by the finite element method. The analysis makes use of the measured residual...
Experiments on Active Structural Control Under Seismic Loads
Two control systems, an active tendon system and an active mass damper system are selected for study for possible real structural implementation. Presented in this paper are simulation...
