A Microcomputer Program for River Sedimentation
Erosion and deposition of sediment in rivers causes numerous problems. In order to describe this process, both the hydraulic properties of the river and the mechanics of sediment transport...
The Effect of Connection Flexibility on Steel Members and Frame Stability
With the advent of Load and Resistance Factor Design (LRFD) and the many existing moment-rotation curves for connections, the use of actual connection flexibility in the design process...
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...
Type C Fly Ash and Clay Stabilization
Because the soils onsite have a high swell potential, a 37 foot high retaining wall was designed with counterforts and was supported by pier foundations to limestone. In order to reduce...
Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....
Design and Performance of Shiroro Rockfill Dam
Shiroro Dam, constructed across the Kaduna River in Nigeria, is a rockfill dam with reinforced concrete facing. The dam was completed in late 1983, and reservoir impounding started in...
Seismic Design of Concrete Faced Rockfill Dams
The results of analytical studies of the stability of the slopes of concrete-faced rockfill dams under different levels of earthquake shaking are presented and used to propose desirable...
The Design of Macagua Concrete Face Rockfill Dam
This article describes the design characteristics of the concrete face rockfill dam at Macagua, which will have a total length of about 9,200 ft (2,800 m), an average height of 66 ft (20,0...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
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...
Application of Methods of Probabilistic Characterization of Soil Properties
The use of probabilistic methods to describe soil properties has many applications. One such application that has been developed is in the area of probabilistic slope stability analysis....
Coefficient of Variation of In Situ Tests in Sand
For a research project on the behavior of piles in sand for the United States Geological Survey and the Federal Highway Administration, ten sites were selected where detailed load tests...
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...
Coal Terminal
The Charleston Shipyard River Coal Terminal was constructed by converting a port-side chemical plant at a third of the cost of equivalent major coal terminals. A staged program for the...
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 and Performance of Buried Fiberglass Pipes ? A New Perspective
The buried performance of fiberglass pipes was the subject of a comprehensive and multifaceted research program carried out in 1982 and 1983. Instrumentation, capable of accurately tracing...
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...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
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,...
