Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...
Lateral Analysis of Drilled Piers Incorporating Soil Variability
In probabilistic studies, the mean or expected value of the parameter in question, along with its measured dispersion or standard deviation, are determined. In this study the Three Point...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
Stochastic Risk Assessment for Structural Safety
Through the United States the structural safety of major and/or innovative structures has become a serious concern for engineers and to the general public. The objective of this paper...
High Strength High Rise
For the sixth time in history, a structure billed as the world's tallest concrete building (over 950 ft) is under construction in Chicago. The contractors describe the structure...
Priority Integrated Pipe Evaluation
The selection of the most suitable pipe for a given site involves the consideration of many factors affecting pipe performance. The factors to consider in sewer pipe evaluation and selection...
A Multilayered Model for Analysis of Composite Pipes
A multilayered model is developed to analyze the behavior of composite pipes, such as prestressed concrete pipe, to the combined effects of internal pressure and applied loads. The pipe...
An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
Rehabilitation of Terminal Ballast Water Piping
In order to maintain the integrity of the ballast water piping system at the Marine Terminal of the trans-Alaska pipeline, a composite lining system was installed in the 42-inch (1,067...
Rehabbing the Underground Railroad
The Park Ave. Railroad Tunnel brings three commuter rail lines into New York City's Grand Central Station. The four tracks occupy three tubes from 97th St. to 57th St., where...
Cement-Based Materials for Planetary Facilities
The use of concrete and other materials based on a cementitious matrix is evaluated for the construction of planetary base facilities. Consideration is given to the most recent developments...
Response of Advanced Composite Space Materials to Thermal Cycling
In addition to microgravity and lack of atmosphere, the space environment provides intense radiation of both penetrating and nonpenetrating types. This paper focuses on the cyclic radiational...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Progressive Impact Damage Assessment in Composite Pressure Vessels
At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Leakproofing an RCC dam
A roller compacted concrete dam, Stacy Dam in Texas, is described and several methods of preventing leakage are mentioned. Reinforced concrete facings, placed after RCC completion, was...
Stopping the Cracks
It is generally agreed that reinforced concrete in parking garages especially in the deicing salt environment is exposed to unusually hostile service conditions. Deterioration of reinforced...
New Horizons in Construction Materials
While civil engineers have, for centuries, built structures and other physical facilities using whatever materials are available to them, there is always the need for stronger, more durable,...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
