Columns and Beams Braced by Diaphragms
Shear-resistant light-gage metal diaphragms, such as wall cladding, roof decking, and floor panels, often are connected directly to beams or columns of a steel framework. Using an energy...

Edge Beam Stiffening of Multibeam Bridges
A method is presented based on articulated plate theory for the determination of the distribution of deflections, moments and forces in bridge decks made up of several beams. The analysis...

Second-Order Theory in Orthotropic Plates
The basic equations for the stress analysis of an orthotropic plate are given. These equations take into account bending and membrane stresses. Various methods of solving the basic equations...

Verrazano-Narrow Bridge: Development and Financing of Project
The Verrazano-Narrows Bridge across the Narrows at the entrance to New York Harbor was built by the Triborough Bridge and Tunnel Authority. It is a key link in the southerly bypass route...

Verrazano-Narrow Bridge: Conception of Design and Construction Procedure
The Verrazano-Narrows Bridge, with a centerspan of 4,260 ft and side-spans of 1,215 ft, has the longest suspended span built to date (1966). With twelve traffic lanes on two decks, it...

Verrazano-Narrow Bridge: Design of Superstructure
The 4,260-ft-long center span of the Verrazano-Narrows Bridge is the longest built to date (1966). The two sidespans are 1,215 ft each. The bridge carries twelve lanes of traffic on two...

Structural Behavior in a Gypsum Roof-Deck System
The results of a study of the structural action of a gypsum slab with steel bulb tee subpurlins and steel bar joist purlins in poured-in-place gypsum concrete roof decks are presented....

Computer-Aided Bridge Design
A computer system to aid highway bridge designers is described. The system integrates data manipulation, analysis, and partly-to-fully automated design routines for short-span bridges....

Design of Concrete Multibeam Bridge Decks
The problem of designing a multibeam concrete bridge consisting of pretensioned beams, in which transverse distribution of the load is obtained by a combination of shear keys and transverse...

Analysis of Orthotropic Plate Bridges
An exact theory for orthotropic plates with either torsionally soft or torsionally stiff eccentric stiffeners, first formulated by Pflüger, is described and generalized. The resulting...

Testing a Light Gage Steel Hyperbolic Paraboloid Shell
Construction and testing of shell using standard light gage steel roof deck panels; panels are welded intermittently along their seams, and at external edges to light perimeter members;...
