Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...

Projectile Penetration Into Reinforced Concrete and Steel Targets
This paper presents brief preliminary results of a research program sponsored by the Air Force Weapons Laboratory (AFWL) to investigate the interaction of 30-mm cannon projectiles with...

Building High Tech in China
The tallest steel structure in the People's Republic of China is being built by an international complement of designers, suppliers, vendors and contractors. It is the 42...

Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...

Building Structures
This volume contains over forty papers from thirteen sessions of Structures Congress '87. The papers include a variety of topics on the overall behavior and design of buildings...

Bridges and Transmission Line Structures
This volume on Bridges and Transmission Line Structures contains papers from ten sessions and one plenary session of the 1987 ASCE Structures Congress. Eight sessions cover bridges. A...

Earthquakes Will Not Damage This Bridge
A California pipeline bridge has been retrofitted with isolation bearings that damp earthquake shocks. The bridge over Southern California's Santa Ana River carries the Upper...

Save the Walls
A rehabilitation job in name only, the 75 year old Army and Navy Club, a landmark located in Washington D.C.'s Golden Triangle, retained only two of its 80 ft high exterior...

The Just-in-Case Factor
Computer analysis allows bridge designers to take a more precise look at the old structural principle of redundancy. No one can define redundancy, but everybody knows what it means. Two...

Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...

Artist in Wood Structures
Julius Natterer is chairman on the Institute for Wood Structures at the Federal Institute of Technology in Lausanne, Switzerland, and designer of more unusual or unique wood structures...

Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....

Exhibits Under Fiberglass
The San Diego Convention Center, scheduled for completion in 1988, is located on 11 acres of downtown land only 150 ft from the bay. It will cost $130 million for total of 1.7 million...

The Sand Bar Hydroelectric Project: A Case History
The Sand Bar project's major features include a reinforced concrete intake structure; 3. 5 miles of twelve foot diameter hard rock tunnel; a reinforced concrete powerhouse...

Carmen-Smith Uprate & Modernization
The Carmen-Smith Powerhouse is located on the upper McKenzie River, 75 miles northeast of Eugene, Oregon. Carmen's two nearly identical 42. 1 MVA vertical hydroelectric turbine...

Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...

Fishery Issues Slow Boardman River Redevelopment
At issue was the requirement of the Michigan Department of Natural Resources (MDNR) and the U. S. Fish and Wildlife Service to require the establishment of fish ladders at the hydro sites....

Seismic Isolation System for a Floating Dry Dock
The seismic isolation system consists of two dolphins, each a relatively large-diameter cantilevered steel pipe pile anchored in Franciscan rock, and buffered connections to the floating...

Steel Poles?Past, Present and Future
When using steel pole structures, construction possibilities are limitless. Of all the options available, tubular steel structures provide the most versatility for transmission line construction....

Lattice Tower Design Using Cold-Formed Shapes
The use of cold-formed shapes in lieu of hot-rolled angles may lead to major changes in the design of lattice transmission towers. The design procedure of the new shapes is more creative,...
