Cost Comparison Of Timber, Steel, And Prestressed Concrete Bridges, Richard A. Behr, E. J. Cundy, C. H. Goodspeed Jan 1990

Cost Comparison Of Timber, Steel, And Prestressed Concrete Bridges, Richard A. Behr, E. J. Cundy, C. H. Goodspeed

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study was undertaken to investigate the economics of timber bridge superstructures versus traditional steel/concrete and prestressed concrete alternatives in the short-span range of 20 to 60 ft (6.1-18.3 m). Only superstructure costs were considered because substructure and abutment costs are highly site-specific. A lack of definitive data regarding service lives and maintenance costs precluded a life-cycle cost study; thus, only initial costs were compared. Representative superstructure designs were obtained for timber, steel/concrete, and prestressed concrete bridges at 20-, 40-, and 60-ft spans. Five to six northern New England general contractors performed cost estimates on these designs. Also, nine timber …


Seal Forces In Structural Glazing Systems, C. V.Girija Vallabhan, Gee D. Chou, Joseph E. Minor Jan 1990

Seal Forces In Structural Glazing Systems, C. V.Girija Vallabhan, Gee D. Chou, Joseph E. Minor

Silicone sealants are used as structural connections between the two glass plates in an insulating glass (IG) unit and between the IG unit and the supporting mullion. These connections become an integral part of the entire glazing system, worthy of attention by structural design engineers. Since the behavior of IG units subjected to lateral pressures, such as wind, is highly nonlinear, von Karman plate equations are employed in the mathematical model developed here. Also, since the two thin glass plates are separated by a sealed air space, a complex interaction occurs between the trapped air space and the glass plates. …


Optimum Assessment Of Irregular Three-Dimensional Seismic Buildings, Kevin Z. Truman, Franklin Y. Cheng Jan 1990

Optimum Assessment Of Irregular Three-Dimensional Seismic Buildings, Kevin Z. Truman, Franklin Y. Cheng

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A structural optimization algorithm based on an optimality criteria approach is presented for three-dimensional, statically and dynamically loaded steel or reinforced concrete structures. The theoretical work is presented in terms of scaling, sensitivity analyses, optimality criteria, and Lagrange multiplier determination. The structures can be subjected to a combination of static and dynamic displacement and stress, and natural frequency constraints. The dynamic analyses are based upon the ATC-03 provisions for equivalent lateral force and modal analysis procedures, or multicomponent response spectra modal analyses. Using the algorithm presented, a computer program called ODRESB-3D was developed for analysis and design of various building …

In the design of steel buildings, the allowable stress design (ASD) method has long been used for cold-formed steel structural members in the United States Recently, the load and resistance factor design (LRFD) criteria have been developed for steel buildings using hot-rolled shapes and built-up members fabricated from steel plates In order to develop load and resistance factor design (LRFD) criteria for cold-formed steel structural members, a joint research project is conducted at the University of Missouri-Rolla, Washington University, and the University of Minnesota under the sponsorship of the American Iron and Steel Institute Based on the 1986 edition of …


Failure Strengths Of Laminated Glass, Joseph E. Minor, Patrick L. Reznik Jan 1990

Failure Strengths Of Laminated Glass, Joseph E. Minor, Patrick L. Reznik

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Laminated glass used in architectural glazing comprises two layers of glass connected by a thin interlayer of polyvinyl butyral. Previously reported nondestructive experimental stress analyses offer evidence that laminated glass behaves like monolithic glass of the same nominal thickness except when temperatures are high. This evidence has been augmented to include failure behavior by destructive tests of a large number of laminated-glass specimens. Test results reveal that failure strengths of annealed laminated-glass specimens are equal to failure strengths of annealed monolithic glass specimens of the same nominal thickness at room temperature and decrease to about 75% of monolithic-glass strength at …
