Beam-To-Column Connections for Pultruded FRP Structures
Moment-rotation and strength characteristics of beam-to-column bolted connections of fiber reinforced plastic (FRP) pultruded wide-flange structural shapes are discussed. Results of experimental...
Properties of Flyash Cellular Concrete
A research program was conducted with the aim of studying the physical and flexural properties of cellular concrete containing flyash. Two different types of fibers were also added to...
Flexural Strength of Externally Reinforced Concrete Beams
Results from tests of one rectangular and one T-beam are reported. The beams were strengthened by epoxy-bonding a 1/4 in. (6 mm) thick Glass Fiber Reinforced Plastic plate along the tension...
Structural Details: Is Anything Missing?
While actual failure of a structure is uncommon, many projects have less publicized, detailing-related difficulties involving rework, changes, clarifications, and increased costs. If the...
Form Follows Geometry
The $107 million NCNB Plaza in Tamps, Fla. consists of a 32 floor, 500,000 sq ft, 455 ft tall office tower; a 40,000 sq ft, 78 ft tall banking hall, and a 280,000 sq ft parking garage...
Vibrations of Linearly Tapered Cantilever Beams
Originally published in: Journal of the Engineering Mechanics Division, ASCE, EM2, April 1962, pp. 95-123...
New Piers for an Old Bridge
Placing new piers under an old superstructure has saved the architecture of the historic Ashley River Bridge in Charleston, S.C. In July 1987, an inspection indicated deterioration and...
Rebuilding Philadelphia's El
In reconstructing an urban transit system, the challenge in Philadelphia was to do it without disrupting peak hour commuter traffic or disturbing activities on the street and sidewalks...
Fabric Meets Cable
The newest generation of fabric-roofed stadiums are cable domes designed by David H. Geiger of Geiger Gossen Hamilton Liao Engineers, New York City. He also uses the term tensegrity coined...
Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...
Cambering of Steel Beams
Cold cambering with force in the fabrication shop is an effective and economical method of compensating for deflections of composite beams. Typical beams should be cambered for dead load...
Engineering Design Concerns Regarding Steel Fabrication
The precise fabrication of structural steel pieces is an essential part of the process leading to the satisfactory erection and connection of the individual steel elements into the final...
Stability of Plates Under Eccentric Edge Loads
A linear finite element analysis was conducted to study the stress distribution in the web and the flange when the beam is subjected to a patch load applied in the plane of the web or...
Analysis of Tapered and Stepped Columns by Analogy to Cantilever Deflection
An analysis is developed for handling the buckling design of tapered and stepped columns with the aid of the so called 'amplification factors'. When these factors...
Behavior of Cold-Formed Steel-Concrete Composite Beams
An experimental investigation was conducted at California State University - Long Beach to study the structural behavior of composite beams made of thin-walled cold-formed steel stiffened...
Cold-Formed Z-Sections Under Axial Load and Bending
The use of cold-formed Z-section members as beam-columns presents some unique design problems which are not adequately addressed in the current design specifications. If these members...
Evaluation of the Rotation Capacity of Wide-Flange Beams Using Shell Finite Elements
Numerical simulation can be useful for planning of experimental tests, performance of parametric studies, and achieving an understanding of complex three-dimensional behavior that may...
Stability Analysis of Steel Compression Members by a Modified Finite Strip Method
The method of structural stability analysis utilized in this paper is a combination of the classical bending theory and the finite strip method. Combining the assumptions of traditional...
Lateral Buckling of Beams: General Considerations
The paper presents a solution for the elastic, lateral-torsional buckling of beams under unequal end moments using Worthington's method of superposition of modes involving...
Automated Design of Reinforced Concrete Components
This paper presents strategies for automating the design of reinforcement in two types of concrete components, namely T-beams and circular columns. These strategies may serve as examples...
