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...
Repair and Rehabilitation of Damaged Steel Flexural Members
In earlier years, the primary method for repairing steel flexural members was to replace the member. However, with the cost of labor and material increasing dramatically over the last...
The Fabrication and Erection of the Minneapolis Convention Center
A new convention center is part of the City of Minneapolis' successful plan to maintain an economically strong downtown core. It is the latest addition to a list of civic...
Double Angle Bracing Members
It has been pointed out that when a single line of bracing is used, the member is usually made from structural tubing. It has been suggested that when the loads are not too great, consideration...
Preliminary Design Considerations for Flat Deployable Structures
Deployable structures are prefabricated frames that can be stored in a compact configuration, and can be easily deployed into a large-span, load-bearing space structure. The interest in...
Some Examples of Latticed Structures in Spain
Since the middle of the last sixties latticed structures have extensively been used in Spain to cover different large areas as factories, churches, marketplaces, exhibition palaces etc....
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...
Design Issues in Steel Buildings
The Committee on Design of Steel Building Structures of the Committee on Metals of the Structural Division of ASCE was formed in 1981, with the express purpose of studying problems that...
Composite Floor Vibrations: Predicted and Measured
Several steel composite floor systems of relatively long span trusses for a number of high rise structures in the Chicago area have been subjected to field measurements to evaluate their...
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...
BABE: An Expert System for Structural Design of Bridge Abutments and Piers
A knowledge-based expert system named 'BABE' (Bridge and Building Evaluation) has been developed for the purpose of helping the user in planning, analysis and...
Superquadric Object Representation for Dynamics of Multi-Body Structures
While the finite element representation of an object in terms of nodal coordinates and shape functions is ideal for representing the stress and energy state, it is not well suited to the...
Polypropylene FRC In Steel Deck Composite Slabs
Engineers, testing laboratories, universities and metal deck manufacturers have studied polypropylene fiber reinforced concrete (FRC) and compared the results with similar slabs reinforced...
Sulfur Polymer Concrete for Special-Purpose Applications
Special-purpose sulfur concrete construction materials, based on sulfur polymer cement (SPC) and mineral aggregate, have been developed by the U.S. Bureau of Mines as part of a program...
Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....
Concrete Lunar Bases
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...
Recent Development of Cement-Based Materials
Development of advanced techniques has enhanced the capability of more accurate characterization of engineering materials at both the microscopic and macroscopic levels. Through better...
Review of Composite Analysis Methods for High Temperature Applications
This paper addresses a number of unique problems encountered in the stress analysis of high temperature composite materials. The materials used as structures subjected to temperatures...
Testing of Reinforced Concrete Bridges for External Reinforcement
Several continuous reinforced concrete slab bridges were constructed in the 1950's with spans ranging from 30 ft. to 60 ft. Longitudinal cracks were observed in the tension...
Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...
