Hydraulic Design Limitations for Gravity Flexible (Non-Rigid) Plastic Pipes Flowing with a Free Water Surface
Hydraulic design limitations are necessary for gravity plastic pipes when designed for use as a sanitary sewer, flowing part full with a free water surface. The limitation for pipes designed...

Rehabilitation of the SF Calawah River Bridge
The failure of a 4-span reinforced concrete bridge in Washington State initiated a study that ultimately led to a unique method of bridge rehabilitation. Severe scour resulted in settlement...

Dynamic Behavior of R/C Buildings in Vi? del Mar, Chile
The Chilean earthquake of 3 March 1985 resulted in an effective peak acceleration of 0. 36g in the coastal city of Vina del Mar. The city had an inventory of over 400 reinforced concrete...

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...

Practical Analysis of Flexibly-Connected Building Frames
Modeling of flexible connection behavior as elastic-perfectly plastic is proposed for analysis of building frames, and results based on this idealization are compared with fully non-linear...

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...

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...

Reliability of Structural Systems With Multiple Limit States
The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection,...

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...

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...

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...

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...
