High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...
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...
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...
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...
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...
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,...
Seismic Design of Underground Structures Southern California Metro Rail Project
The effect of earthquakes on underground structures is the imposition of an arbitrary deformation which cannot be changed by strengthening the structure. The structural design goal is...
Seismic Risk and Decision Analysis of Lifeline Systems
This paper provides general guidelines for performing lifeline seismic risk and decision analyses. Relevant input models are introduced as they support the performance of component and...
CSMIP Strong-Motion Instrumentation and Records from Transportation Structures?Bridges
Seven transportation structures have been instrumented by the California Strong Motion Instrumentation Program (CSMIP), including four bridges. Records (in excess of 0. 25 g maximum acceleration)...
Seismic Design of Airport Control Towers
The paper describes state-of-the-art design in seismically active areas. It includes a review of current code design parameters and specific tower design criteria. Tower design examples...
Port of Seattle Seismic Waterfront Design
This paper describes the soil seismic design process, using the design developed for a concrete apron project at Terminal 20 as an illustration. Damage by the 1965 earthquake is described....
Seismic Response of Port and Harbor Facilities
A research program compiled information regarding the behavior of port and harbor facilities during past earthquakes. The potential for significant damage to port and harbor facilities...
