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...
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...
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...
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...
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...
Dynamic Response Correlation of Cylindrical Tanks
The May 1983 Coalinga Earthquake provided an opportunity to correlate earthquake performance of cylindrical liquid storage tanks with behavior observed in laboratory shaking table experiments....
Seismic Risk and Reliability of Telecommunications Systems
A general method for seismic risk analysis of telecommunications sytems evaluates by statistical means the earthquake environment and the earthquake vulnerability and effects on the system...
Dome
Roofed with the worlds largest diameter wood dome at 530 ft., the Tacoma Dome, a multi-purpose sports and convention center has helped revitalize a blighted part of that Washington state...
Retaining Wall
The foundation of this off-ramp in Manchester, New Hampshire is made up of end-bearing piles and sloping rock anchors�an innovation that is unique to the United States. End bearing piles...
A Systematic Approach to Conducting Seismic Margin Reviews for Nuclear Power Plants
Deviations from the current codes and standards are considered acceptable in a SMR in areas where the design criteria impose significant conservatism provided the intended function of...
Response of Subsystems on Inelastic Structures
Preliminary analyses are performed to obtain insight into the seismic response of subsystems supported on simple structures that yield during severe earthquake ground motions. Current...
Seismic Evaluation of Non-Seismically Designed Existing Magnox Nuclear Power Plants
Special procedures included on-site testing with a portable shake table, low vibration testing using a structural dynamics analyser, and on-site inspections. The low vibration testing...
Update on Impact Effects in Nuclear Plants Part I?Overview and Need for Integrated Approach
In this paper, an ASCE working group on impact effects in nuclear plants updates the review of this technology contained in a five-year-old ASCE report. In Part I, an overview is given...
Update on Impact Effects in Nuclear Plants Part III?Review of Heavy Object Drop
The consequences of an accidental drop of a heavy component from a lifting device in a nuclear power plant are required to be evaluated even though the device may have been designed using...
