Shear Strengths of Concrete-Filled Steel Box Elements
This study evaluated the ultimate strengths as well as the effect of the ultimate composite actions of concrete-filled steel composites under combined bending, shear, and axial forces....
Microcomputer Analysis of Harbor Wind Drift
A microcomputer with general-purpose spreadsheet software was used to analyze wind drift on the water surface of Quincy Bay in Boston Harbor. Wind drift is the movement of the surface...
Computer Conferencing for Managers
The authors describe a computer conferencing/message system called Confer II currently being utilized by the US Army which they have implemented among dredging managers in the US Army...
Computer Aided Design Using CORPS
The Hydraulic Analysis Division, Hydraulics Laboratory, US Army Engineer Waterways Experiment Station (WES) has the responsibility for developing and disseminating hydraulic guidance for...
Staggered Truss Adapted to High Rise
The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss,...
Dynamics of Buried Pipelines
Forced motion of pipelines due to stationary or moving loads is studied. The pipe is modeled as an elastic shell in an elastic (or viscoelastic) medium. The interaction of the shell and...
Behavior of Cavity Masonry Walls Under Out-of-Plane Lateral Loading: An Analytical Approach
In this paper, a finite element model is used to analyze cavity walls in an attempt to understand their complex behavior and to evaluate the adequacy of the assumptions embodied in the...
The Resident Engineer?Experience and Judgment
This paper gives the author's definition of the Resident Engineer. The duties, responsibilities, qualifications and authority of the U. S. Naval officers assigned as Resident...
Navy Construction Contract Administration
A U. S. Navy Civil Engineer Corps Officer portrays the varied responsibilities of a Resident Engineer administering construction contracts for the military service. The challenges, rewards...
Advances in Short Span Steel Bridges
Applying recent research to the design of short span steel bridges can lower their cost and maintenance. Such research involves improved limit state criteria, more uniform lateral load...
Seismic Design for Highway Bridge Foundations
This paper focuses on the determination of stiffness characteristics of piles and pile groups. Both battered and vertical pile groups are considered. Recommended methods for determining...
The Use of Joint Reinforcement in Qualifying Masonry Walls in Nuclear Power Plants
Wire joint reinforcement has been traditionally used in block masonry walls for crack control and to provide continuity for multiple wythe walls. In a number of nuclear power plants, vertically...
Design of Thin Wall Reinforced Concrete Pipe Using Dimension Ratio (DR)
Dimension Ratio is defined as the ratio of the internal pipe diameter to the pipe wall thickness. The Caltrans culvert research leading to the development and use of the Dimension Ratio...
Evaluation of P-Y Relationships in Cohesionless Soils
Four semi-empirical procedures for construction of p-y curves in cohesionless soils were developed to fit data from a particular load test or a specific set of tests on similar soils....
Evaluation of P-Y Relationships in Cohesive Soils
The practice of analyzing laterally loaded driven and bored piles often requires modeling of soil response in terms of uncoupled, non-linear unit load transfer functions. These functions,...
Lateral Load Tests of Piles in Sloping Rock Fill
A new container wharf constructed at the Port of Los Angeles features vertical prestressed concrete piles to provide both vertical and lateral support. A rockfill embankment used to allow...
Pile Caps Subjected to Lateral Loads
This paper reviews current pile cap design practices and presents results of tests on two pile caps with different reinforcement locations. Lateral load tests performed on two pile cap...
The Corps' Environmental Effects of Dredging Programs
The major programs addressing environmental effects of dredging and disposal that have been or are being conducted by the Corps since 1973 are: Dredged Material Research Program, Dredging...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
