CADD Application to Structural Framing Systems
This presentation illustrates the formulation of a Computer Aided Analysis/Design/Detail (CADD) program package utilizing a common microcomputer data base. It presents a new CADD technique...
Software for Optimum Design of Highway Bridge Beams
A software system for analysis and optimum design of welded plate beams subjected to AASHTO highway bridge loads and specifications is described. The system has the capability to design...
Interactive Microcomputer Analysis and Design of Light Gage Steel Roof Systems
A hinderance to the widespread acceptance of the cold-formed steel roof Z-purlin in conventionally engineered buildings is due to the lack of a useful and efficient analysis and design...
Microcomputer Expert Systems for Welded Construction
Stone & Webster Engineering Corporation has developed expert systems including various applications within the field of welded construction. Systems have been developed in the...
Finite Element Analysis of Structural Details in Large Steel Bridge Superstructures
Various approaches for the finite element modeling of the connection details in large steel bridge superstructures are presented. It is noted that an accurate analysis of these details...
Computer Simulation of the Overload Behavior of Steel Multigirder Bridges with Cracked Girders
Various approaches of determining the structural response of steel multigirder bridges with cracked girders are presented. It is noted that linear finite element packages with three dimensional...
Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...
Steel Bridge Counterattack
In bridges, for years steel has been losing market share to concrete, but now the steel industry is making an impressive comeback. One reason is use of load-factor design, which has cut...
Shopping for a New Bridge Coat
Total shop coating of new steel bridges appears to be the best armor against corrosion. This alternative is one of three techniques for diminishing the difficulty and expense of painting...
Building on Water
During the last century, innovations in concrete have paved the way for the evolution of marine concrete structures. Oakland's proposed Carnation Container Terminal is using...
Celebrating a Conquest
During construction of the San Francisco-Oakland Bay Bridge, which marked its 50th anniversary on Nov. 11, 1986, great public attention was paid to the high-climbing steelworkers, but...
Soil Nailing a Wall
Soil nailing is the reinforced-earth idea (in which the earth must be backfilled behind the wall) applied to cut situations. Soil nails are an inexpensive post-tensioned tieback, consisting...
Isolating Earthquakes
The Foothills Communities Law and Justice Center in Rancho Cucamonga, Calif., is the first U.S. building to rest on base isolators for protection against a possible earthquake of 8.3 Richter....
Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...
Experimental Assessment of Performance of Bridges
Among the papers in this book, five assessed the global bridge behavior and the three concentrated on bridge decks. The bridges assessed include prestressed steel plate girder and truss...
Wharf Stands on Stone Columns
A wharf was constructed in New Orleans on very weak soils. To prevent lateral and vertical movement of the soil, normally the entire wharf and adjacent structure would be founded on steel...
Design Flexibility Cuts Costs
The Los Angeles Water Department saved $5 million on a pipeline project by investigating the capabilities of pipe fabricators to furnish the pipe size required and by being open to alternate...
China Builds Record Bridge
China's Hanjiang Railway Bridge has a 1,000 ft (305 m) long main box girder and is the longest bridge of its type in the world. The steel box girder bridge is built with a...
Ice-Structure Interaction of an Offshore Platform
Realistic estimation of the effects of ice floe impact is desirable for the design of certain sub-arctic offshore structures. The results of a preliminary study on dynamic ice-structure...
SHADS: Mobile Arctic Drilling Platform
To minimize costs of Beaufort Sea exploration programs, the industry needed a mobile arctic drilling structure that requires little or no site preparation, does not require an active ice...
