Dam Anchored to Foundation to Withstand Floods
Federal Power Commission Order No. 315 required a safety review of Conowingo Dam and Powerhouse by an independent board of consultants. As recommended by this board, a study was made of...
Retaining Walls: Taking It From The Top
Since 1958, fully anchored curtain walls have been used increasingly to retain slopes in Brazil where topographic, climatic, and geologic conditions are extremely favorable to landsliding...
Stadium Seats Slide on Water
In Denver, a unique 21,000 seat, 9-million pound movable stand is used to convert the Denver Mile High Stadium from baseball to football or soccer. The stands are lifted and move on 163-forty...
Reef Runway is First in Airport Design
The Reef Runway Project of Honolulu International Airport constructed on a coral reef, provides approximately 765 acres of new land for the 12,000-ft-long runway with its associated taxiways...
Cofferdams�Economical Flood Protection
Houston Lighting and Power Co. Sam Bertron Generating Station, located on the Houston Ship Channel, had suffered a drop in elevation of 7.5 ft since its construction in 1954. At such a...
Reliability and Limit States Approaches to Design
Increasingly, designers of structures and other civil engineering projects will be designing in these ways. What is the reliability approach? It is based in part on the fact that the magnitude...
Chevrolet Raises the Roof
Chevrolet's Gear and Axle plants in Detroit needed more space so a decision to renovate the 60-yr old structures rather than relocate the operation was made. New roof structures...
Prefab Structural Components Solve Expansion Problem
Another story was added onto an existing low-rise building, where soil strength was so low that the new floor had to be built by sinking new columns down to a sounder stratum, placing...
Drexel Students Build Space Frame as Senior Project
Drexel University's geodesic tri-span is an open-air monumental structure conceived, designed, fabricated and constructed by a group of senior civil engineering students to...
Germany, Belgium and Los Angeles have Mandatory Design Review for Major Structures
The report of the engineering investigation into the causes of the collapse of the Hartford Coliseum space truss cited design deficiencies as the cause of failure. That report also says...
Subway Designs and Construction Methods That Cut Costs
The high cost of subway construction in the United States can be reduced by adopting station and track structure configurations, structural systems, and construction techniques best suited...
Gophers Go Underground
A major facility, Williamson Hall, was constructed to be almost entirely below grade on the East Bank Campus of the University of Minnesota. Heating and cooling energy requirements will...
Modern Concrete Structures Survive Romanian Earthquake
On March 4, 1977, 35 buildings collapsed during a severe earthquake (7.2 on the Richter scale) in Bucharest, Romania. Thirty-two of the 35 were older structures, erected before World War...
Reliable Structural Weldments for Critical Service
Fracture control plans are considered in light of weldment rather than base material alone. Data are presented on the probability of base materials (i.e., plate) having adequate toughness...
Energy Facilities Going Underground
Environmental pressures, combined with continuing development of hard-rock excavation techniques, have turned attention to the placement of major engineering facilities underground. Primary...
Proceedings Volume I
Polyphase Flow Transients Pressure Recovery Devices Intake Structures Cooling Water Systems
The papers presented in these proceedings represent a variety of disciplines from many countries. This unique jointing of three major societies has created a collection of papers with...
Filter Fabrics in Shore-Protection Structures: Save Money, Ease Installation
Over the past decade, plastic filter fabrics have seen growing use in shore-protection structures (e.g. revetments, breakwaters, jetties), river-bank protection schemes, and other areas...
Exxon's Offshore Platform Nearly Doubles Water-Depth Record
In 1976, Exxon erected near Santa Barbara (Los Angeles metropolitan area) the Hondo platform, in 850 ft of water. This is nearly twice the previous record depth established in the North...
Precast Veneer Replaced By All-Precast Structure
Utilizing engineering solutions to architectural problems greatly enhanced the architectural appearance of this building. Long-span prestressed, light weight concrete beams, post-tensioned...
Vibroreplacement and Reinforced Earth Unite to Strengthen a Weak Foundation
Two relatively new engineering concepts in the U.S. were successfully used to solve a difficult soils problem. A highway skirting Idaho's Lake Pend Oreille was built on a...
