Fatigue Strength of Welded Wire Fabric
Long life fatigue tests were made on 12 concrete slabs reinforced with large diameter, Grade 75, deformed welded wire fabric. The specimens simulated, to full scale, conditions in a bare...
Base Isolation for Reinforced Concrete Structures
A recent experimental program has been carried out at the Earthquake Simulator Laboratory of the Earthquake Engineering Research Center in which a 1/5th scale reinforced concrete structural...
Thin Precast Fiber Reinforced Cement Panels
This paper provides an overview of some current applications, manufacturing methods, and physical properties of thin fiber reinforced cement board products currently produced. Many of...
Polymer Concrete for Structural Applications
Polymer concrete (PC) has been used extensively in the United States primarily as a repair material for portland cement concrete. The excellent flexural and compressive strength durability...
Chemical Admixtures for Concrete, What is in Them for the Structural Engineer?
The paper summarizes the effect of admixtures on the economy in construction of concrete structures, on their strength, and on their durability under a variety of service conditions. As...
High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...
Structural Considerations of Cellular Concrete
Although not normally considered to be a structural material, cellular concrete possesses characteristics which may result in its having structural applications in building and structural...
Concrete Shell Design for Membrane Stress
A methodology is presented which covers the design of reinforced concrete shells for membrane stress. The methodology follows the strength design method of the ACI 318-83 Building Code...
Large Reinforced Concrete Active Reclaim Silos
The design and construction of large reinforced concrete shell silos used to provide economical short-term protected storage for coal and lignite in the active reclaim systems of power...
Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...
The Ultimate Load Design Method of R/C and P/C Shell
Based on the testing results of 20 full size shells and models, the ultimate load analysis method is proposed to design four different kinds of reinforced concrete shallow shell structures....
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...
Detecting Underground Piping Leaks
Most leaks from underground liquid storage systems occur in the piping rather than the tank itself. The piping system is the most vulnerable component of the system, requiring great care...
Sewers Get a Breath of Fresh Air
Domestic sewage pump stations and treatment facilities have long been plagued by corrosion and odor problems caused by hydrogen sulfide. It is also extremely toxic. Sulfide production...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
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...
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...
Rehab Roundup
Four recent rehabilitation projects are described. On an old concrete gravity dam, post-tensioning tendons were added to improve its resistance to sliding. The abandoned Union Station...
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...
