Reinforcing Roof Truss Frames Under Load
Without altering the roof structure of an industrial boiler plant, a long-span steel truss frame was modified in place to support heavier loads. The owners of an industrial boiler plant...
Superfund Cleanup Sites
Cleanups of four Superfund hazardous waste sites are described, two in Pennsylvania, one in Tacoma, Wash., and one in Globe, Arizona. The key chemical wastes were polychlorinated bipheynls,...
Managing Overhead in Consulting Engineering Firms
One of the ways an engineering firm can maintain - or increase - profitability is through judicious management of overhead. Yet various industry studies suggest that the typical engineering...
Computing in Civil Engineering
A broad spectrum of computer applications in civil engineering is covered in 73 papers presented at the Third Conference on Computing in Civil Engineering. Emphasis is on microcompters...
Just a Few More Tests and We'll Be Sure
This short paper presents a practical approach to data analysis, with the intent of suggesting that simple statistical methods - when tailored to geotechnical problems - do in fact provide...
Probabilistic Nature of Soil Properties
The integrity of a soil material is defined not only by its compositional components but also by the constituent natural bonds and the resultant interactions between the various constituents...
Principles of Probabilistic Characterizations of Soil Properties
Sources of uncertainties affecting characterization of soil properties in a homogeneous soil layer include inherent spatial variability, systematic test bias, random test errors, calibration...
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....
Characteristics of Indiana Soil Properties
The Indiana Geotechnical Data Bank was established to collect engineering soil data in the state and to provide information for engineering planning and design works. It contains nearly...
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...
Probabilistic Characterization of Nigerian Falls
A probabilistic method of subsurface characterization is developed for sites in Southern Nigeria. This method is based on the use of statistics to analyze real field data and determine...
An Extreme-Value Model for Strength of Stiff Clays
The role of the distribution function in the safety analysis of soil structures is briefly discussed. Comparison of the two statistical distributions - normal and Weibull - reveals that...
Landform-Based Characterization of Soil Properties
A probabilistic characterization of site soil properties can be achieved with sparse site-specific data by augmenting them with data available from other sites in the region having the...
Steel Girder Bridge Sets Record Length
The Veterans Memorial Bridge at Ottawa, Ill., is the longest plate girder, stringer type bridge in the country with spans of 385, 510 and 305 ft. Value engineering played an important...
Building Failures�Construction Related Problems and Solutions
A leadership group of representatives from the fields of structural design, construction, building inspection, the law and insurance agreed that if five changes are made in the way building...
Probabilistic Characterization of Soil Properties
Bridge Between Theory and Practice
The two objectives established for these proceedings are: (1) to summarize the principles and procedures of probabilistic characterization of soil properties in a readily understood manner...
Frost Action and Its Control
This state-of-the-art review addresses, in four separate papers, frost heave processes and their control. A review of the fundamental principles of soil freezing and thawing is presented...
LAX Takes Flight for the 1984 Olympics
LAX (the Los Angeles airport) had over two dozen contractors working on site to complete their $700 million improvement plan in time for the Olympics in July. They also came up with several...
The Sand Dam
Currently under construction is the 443 ft. high sand fill dam. Being erodible, pervious and liquefiable, sand would normally be considered as n unsuitable material to construct LaVueltosa...
Building Failures: Design Problems and Solutions
A Building Failures conference of the Engineering Foundation dissected the problems leading to failures and recommended ways to reduce failures. This article discusses value engineering,...
