Protecting Post-Tensioning Tendons in Concrete Structures
Patterns of corrosion problems related to tendon systems are analyzed based on the author's experience in evaluating over 50 corrosion related performance problems in prestressed...
Swiss Bridge Design Spans Time and Distance
Having long played crucial roles in Switzerlands history, modern bridges there now lead technical innovation in design and construction. Two recently completed Swiss Bridges bridges of...
Notched Trusses Give Low-Cost Conversion of Hangars for Jumbo Jets
Physically notching the structural members in a hangar roof solved the problem of moving new DC-10 aircraft into and out of maintenance hangars built for smaller, earlier-generation commercial...
Full-Depth, Full-Width Design, and Prestressed Concrete Pave the Way for Arizona's Highways
In an attempt to resolve design problems of Arizona's non-reinforced portland cement concrete pavements, a series of test installations are being made involving a comparison...
Philadelphia Bridge Sparked Growth of Prestressed Concrete in the U.S.
Prestressing has been used for centuries. For instance, iron bands were heat-shrunk over built-up wooden wheels to increase their resistance to damage. In 1888, a man named Jackson from...
Nambe Falls Dam�First Mechanically Prestressed Concrete Dam in U.S.
An unusual combination of a curved earth embankment, a concrete gravity thrust block, and concrete thin arch prestressed with embedded vertical flat jacks has created Nambe Falls Dam,...
The birth and growth of history's most exciting building material
Not until the early decades of this century did this most revolutionary of all structural materials arrive-prestressed concrete. Developed in Europe, prestressed concrete began its rapid...
Structural Failures and How to Prevent Them
Reducing failures of buildings and other structures requires compentent design; clear communication of that design to the contractor by means of engineering drawings, etc.; careful and...
