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...
Quantifying Quality Improvement Programs
Structural codes are evolving to a limit state design basis in which the safety checks are derived from the underlying probability distributions of strength and loads. An example safety...
Fatigue Reliability of Ship Hull Girder
Based on estimates on uncertainties in wave loading and fatigue capacity the fatigue reliability of ship hull girder is calculated with respect to global vertical wave bending moment....
Diffusion Models of Crack Growth Due to Random Overloads
Stochastic diffusion models of crack growth are developed, reflecting uncertainty in applied loading and residual stresses near the crack tip. Applications are shown to (1) random vibration...
Building Code Requirements for Masonry Structures and Specifications for Masonry Structures
The proposed Building Code Requirements and Specifications for Masonry Structures presented in this book were developed by the Joint American Concrete Institute, American Society of Civil...
A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...
Swiss Cheese Box Girders
Now going up in the French Alps, the Sylans and Glacieres viaducts have decks supported by three-dimensional arrays of concrete trusses. The superstructures look like concrete box girders...
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...
Dilatometers Settle In
The benefits of the dilatometer test DMT are described. This geotechnical in situ testing tool was developed and patented by an Italian professor and engineer named Silvano Marchetti....
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...
New Installation Designs for Buried Concrete Pipe
The rational development of new installation designs for buried concrete pipe is described. Over 100 analyses were performed using a new computer program named SPIDA (Soil Pipe Interaction...
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...
Successful Rehabilitation of Sewers at Hawaii Kai
Two common problems in sanitary sewer deterioration are hydrogen sulfide attack to concrete pipe and structures and infiltration leakage into the system. Within the 100 miles (160 km)...
The Use of Restrained Joint Ductile Iron Pipe
This paper addresses some of the problems we at U. S. Pipe have observed from restrained joint installations during the past several years and the solutions devised. The restrained joints...
An Investigation of the Supports of a Water Main
Two 48 inch (1. 22 m) diameter cast iron pipes constructed 50 to 70 years ago form a major part of the potable water transmission system of Atlantic City. For the most part of their length,...
Monitoring of a Gas Main During Construction
This paper focuses on the task of formulating and implementing a viable plan for protecting an existing gas main located in a construction site where construction activities include excavation,...
Cables in Trouble
Having inspected more than half of the world's cable stayed bridges, the authors conclude that many are in danger of sudden collapse unless corrosion problems can be stopped....
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...
The Heavy Duty Geogrid Wall
The geogrid reinforced soil retaining wall was a key component in reconstructing a small hydroelectric plant situated at the center of Cascade Dam in Michigan. It was necessary that the...
