Flanged Reinforced Concrete Flexural Members
Design aids in the forms of charts and tables are available for design of reinforced concrete flexural members. Many of these design aids were developed for design of rectangular cross...
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
Grouting in Geotechnical Engineering
The 63 pages included in these proceedings came from 12 different countries and deal with the pertinent advances in grouting materials and technology that have occurred throughout the...
World's Largest Installation of Fabric-Formed Pile Jackets
One major feature of fabric forming is permeability. One application of this technique is protective encasement of steel H and pipe piles at a major pier in Chile. The Huachipato Pier...
Engineer's Notebook: One-step Formula for R/C Tension Steel
In the design of reinforced concrete beams, after loadings and materials are defined, the first step is to assume a beam depth. Then the required steel area and beam width are determined....
Causes and Preventions of Lamellar Tearing: Engineer's Notebook
Within the past 10 years, a steel cracking problem, lamellar tearing, has arisen after welding of thicker sections and higher-strength steels. A separation underlying a weld joining plate...
Fiber-Reinforced Concrete Proves Worth for Airport Pavements
Laboratory and field tests indicate that fiber-reinforced concrete has higher flexural and tensile strength, higher impact resistance, and improved resistance to spalling and joint deterioration...
Steel Cable-Stayed Bridges: Can They Compete in the U.S.?
During the past decade, concrete bridge designs have been winning more bids for contracts than steel cable-stayed bridges. Reasons for this trend are examined. A brief evolution of bridge...
Trouble Shooting ChemicaLly Resistant Masonry
This paper is a series of case histories showing specifically how lack of understanding of the nature of the materials and their proper uses has caused failure in design, specification,...
State-of-the-Art Report on Finite Element Analysis of Reinforced Concrete
This comprehensive state-of-the-art report contains a summary of the special features of finite element analysis applied to reinforced concrete, including: constitutive relationships,...
Steel Structures Provide Flexibility
The steel structures of several major buildings are evaluated by the structural engineers responsible for the design and construction. Included are the Park Avenue Atrium in New York;...
What Type of Sewer Pipe is Best? Life-cycle Cost Analysis Yields Answer
In the past, many engineers have selected the type of sewer pipe for a particular project based mainly on a comparison of initial costs of concrete, steel, and other types of pipes. This...
Fiber Reinforced Concrete
In the past 10 years or so, concrete reinforced with fibers one or two inches long has begun to be used, first on a demonstration and experimental basis, then in major everyday applications....
Compression Rings Support Deep Cut
The plans for building the Cuyahoga Valley Interceptor Lift Station in Cleveland, Ohio, called for 126 ft. (38.4 m) by 105 ft. (32 m) construction, some 80 ft. (24.4 m) below grade. Bracing...
The ABC'S (and Q) of Cold-Formed Steel Design
Cold-formed structural members are steel components that have been put into their cross-sectional shape by cold bending of flat sheets. Local compressive buckling must be carefully considered...
Design and Construction of World's Tallest Free-standing Fiberglass Stack
The design, fabrication and erection procedures are discussed for a 170-ft free-standing fiberglass reinforced plastic exhaust stack-scrubber system. Advantages and disadvantages in the...
General Principles for the Stability Design of Metal Structures
The Structural Stability Research Council (SSRC) Technical Memorandum No. 5 is explored; this memorandum includes the general principles that form the bases of various SSRC recommended...
Luxury Hotel Features New York's First 8,000-psi Concrete
Designers of New York's $100-million Helmsley Palace Hotel realized significant economies by the use of high-strength concrete to replace structural steel and reduce column...
Synthetic Fabrics for Reinforced Embankments
Non-woven permeable synthetic fabrics have been used in engineering applications for the last ten years. Considerable research has been conducted throughout the world since the first geotechnical...
Dallas College Features Load-Bearing Brick Cavity Walls
