Flexural Strength of Ultra-High Strength Concrete Members
Various proposals have been made for the pridiction of strength of high strength concrete sections. One of the most important parts of any strength computation procedure is the assumption...
Wind Resistant Design Manual for Highway Bridges
The new wind resistant design manual for highway bridges has been required recently in Japan. The working group was organized in the Japan Road Association is 1984 to prepare the manual....
Status of Structural Engineering Research
Problems and opportunities for structural engineering research are being addressed in a study by the ASCE Structural Division Task Committee on Structural Engineering Research Needs/Funding....
Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...
Member Design Equations for a LRFD Wood Specification
A key step in the preparation of a load and resistance factor design (LRFD) based design specification for engineered wood construction is the selection of the behavioral equations for...
LRFD: Progress for Engineers and the Wood Industry
The LRFD for Wood project represents a milestone for the industry. The significance of the project goes far beyond merely switching formats in design equations. The project signifies both...
Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...
Analysis of Glulam Lattice Dome
Glued-laminated timber (glulam) domes have become competitive in the engineering of large-span roof structures. Three-way glulam grid domes, such as the Triax and Varax domes, are particularly...
Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...
An Overview of the U.S. Coordinated Program for Masonry Building Research
The U.S. Coordinated Program for Masonry Building Research is a time-phased set of specific research tasks addressing materials, component and system behavior. The objective of the program...
In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...
Use of Experimental Data to Develop Probable Behavior
The intent of this paper is to present results of research that studies the performance of the University of Colorado walls tested by Professor Benson Shing. These walls would be classified...
Durability Design for Concrete Bridge Structures
The concept of durability design for concrete structures including bridge structures is proposed on the basis of comprehensive evaluation of materials, design details and construction...
An Education in Tunneling
In this follow-up to the author's article in the April 1989 issue of Civil Engineering, this senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Fast Tracking Military Waste
The installation restoration program, the military version of Superfund, helped fast track the cleanup contracts for four military hazwaste sites located at Hanscom Air Field, Bedford,...
Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...
Building a Better Landfill Liner
A soil liner project was sponsored by the EPA to provide information on the construction factors that affect the permeability of compacted soil liners. After construction of a field liner,...
Ductility and Failure Characteristics of Concrete and Rock Subjected to Complex Load Paths
Strength, ductility and the complex material response features of concrete and rock should be evaluated through carefully planned material properties test programs designed to subject...
