Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...
Aesthetic Issues in Timber Bridges
The vocabulary of visual design and several generally accepted major principles of visual design are reviewed in order to provide a 'context' for case studies of award-winning timber bridges....
Development of Hardwood Glulam Timber Bridge Standards
Design standards and specification for 5.5 to 27.4 m(18 to 90 ft.) clear span hardwood glued laminated (glulam) highway bridges have been developed and are available from the Pennsylvania...
Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...
Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...
LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...
What Controls the Ultimate Load of a Glulam Dome?
A glulam dome is analyzed with the finite element method to determine the governing failure mode and ultimate snow loads. The dome consists of a triangulated network of curved glulam beams,...
Timber Structures
This paper deals with three different curvilinear timber structures of moderate spans - 120 feet to 200 fee +/-. In each of the three cases cited, the roof deck and boundary members are...
Experimental Study on a Buckling Behavior of a Wooden Single-Layer Space Frame of Reticular Shell on a Hexagonal Plan: Influence due to the Bolted Joint Looseness with Axial and Bending Resistance
The authors have investigated about the structural behavior of a wooden single-layer space frame structure with the bolted joints. We have carried out a buckling tests of a wooden single-layer...
Design and Construction of the Cable-Stayed Wooden Space Truss Roof
The thinning must be enforced for healthy development of an artificial forest. The most effective use of thinning lumber is construct of the space truss structure. This election systems...
Architecture and Lightweight Structures: A Methodical Design Approach
Lightweight structures such as membrane structures, shells, space-grid, lightweight trussed and suspended structures have become an integral part of the international building scene. While...
Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...
Computer Analysis of Lateral Loading in Wood-Framed Structures
Building codes and design techniques associated with single-family housing need to incorporate advances in architecture and construction so that the traditional life-safety building codes...
Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
Model of an Upgrade
As further studies and more extensive computer models help engineers better understand the workings of wastewater treatment plant processes, those engineers are finding more efficient...
In Rehab We Trust
Glulam structures will be durable and last for a long time provided structural elements are protected from water and moisture. Once water is allowed to come into direct contact with glulam...
The Mexican Migration
The North American Free Trade Agreement has made Mexico an attractive market for U.S. firms, particularly in the environmental field. At the same time, privatization (as with toll roads...
Connectors for Earthquake Resistant Structures
Damage assessments from the past several earthquakes located on the northern, central and southern zones of the San Andreas Fault - Cape Mendocino: April 1992, 7.1; Loma Prieta: October...
The European Approach to Seismic Design of Engineered Timber Constructions: The Case of Low-Dissipative Structures
In the present paper the importance of the dissipated energy on the actual structural behaviour of low-dissipative structures as glulam portal frames with mechanical fasteners under seismic...
A General Hysteresis Model for Wood Structures
To predict the dynamic response of a wood structure, its energy dissipation mechanism and hysteresis behavior must be appropriately modeled. This paper presents a new hysteresis model...
