Comparisons of Full Scale and Wind Tunnel Model Response to Wind of Long Span Bridges
There are several vital reasons for measuring the response of full scale structures to wind and comparing the results to models - both experimental and analytical - employed in design....
Wind Forces Measured on a Tall R.C. Chimney
This paper describes some aspects of an analysis performed on measurements of a variety of parameters relating to the wind, wind forces on and the response of a tall chimney. The results...
Improved Design Procedure for Shallow-Buried Structures to Resist Airblast Loading
Both conventional and nuclear weapons generate airblast loads of sufficient magnitude that structure survival at acceptable cost favors below grade construction. The design of shallow-buried...
Drop Test of Dolos Armor Units
Dolosse are concrete armor units used for the cover layer on many breakwaters and jetties. In order to study their complex loads and structural response, a prototype study at Crescent...
Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...
Fatigue Design Criteria for Welded Steel Details
A review of fatigue data and reassessment of the 1983 fatigue specification resistance functions has been conducted. Since the AASHTO specification fatigue resistance provisions were introduced...
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...
Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...
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...
