Press-Lam Timbers for Exposed Structures
Parallel Laminated Veneer (PLV) products are manufactured by adhesive bonding of rotary-peeled veneer. It has been estimated that a production line PLV process could convert green logs...

Tensile Strength of L3 Douglas-Fir Glulam Members
Tensile tests were performed on 335 full-size glued-laminated members made up wholely of grade L3 Douglas-fir and larch laminations. The variable studies were: thickness of laminations,...

Glulam Design Criteria for Temporary Structures
If temporary structures having lives of 2 yr-5 yr are designed using criteria for permanent structures with lives of 50 yr-75 yr, overly conservative design can result. This paper presents...

Road Accidents
A realistic evaluation is attempted of the underlying human instincts and weaknesses contributing to the complexity of the road accident problem. The thin veneer of civilization is stripped...

S. Pine Beams from E-Rated and Proof Loaded Lumber
Prior publications have reported the development of an E-rating and tension proof loading method for selecting material for placement in glued-laminated...

Nonlinear Analysis of Laminated Cross-Ply Plates
Nonlinear bending of unsymmetrically laminated cross-ply plates has been the subject of some investigations. Utilizing the multiple Fourier Series method the writers have examined the...

Nonlinear Analysis of Composite Laminates

Precast Veneer Replaced By All-Precast Structure
Utilizing engineering solutions to architectural problems greatly enhanced the architectural appearance of this building. Long-span prestressed, light weight concrete beams, post-tensioned...

502-ft Diameter Laminated-Timber Dome Provides Fast, Low-Cost Cover for Arizona Stadium
Varex Dome, a 502-ft diameter engineering marveel of glue laminated timber, was built in record six months erection time. This dome shell structure forms both walls and roof for the new...

Mechanical Connections for Structural Plastics
A survey of existing literature on mechanical connections of structural plastic components reveals a dearth of hard data available for civil engineering type materials. The largest body...

Design of Double-Tapered and Curved Glulam Beams
A new rational and simplified design procedure for double-tapered pitched and curved glulam beams, based on extensive theoretical and experimental analyses of this type of beam, is presented....

University of Idaho Barrel-Arch Roof Wins Outstanding Structural Engineering Award
The world's longest span wood structure now covers the football stadium at the Univ. of Idaho in Moscow, Idaho. The trussed arch consists of an upper and lower wood deck connected...

Transverse Bending of Laminated Anisotropic Plates
This technical note is motivated by an earlier paper on laminated anisotropic plates which are symmetric about their midplanes, as well as by a recent reconsideration of the effect of...

Tension Proof Loading for Southern Pine Beams
E-rating (measuring modulus of elasticity) and tension proof loading of lumber before laminating could improve stiffness characteristics and allowable design stresses for glued-laminated...

Laminated Timber Logging Bridges in British Columbia
The forest roads of British Columbia provide examples of large and complex single-lane industrial bridges for logging trucks up to 150 tons. A common element is the large pressure-creosoted...

Wood Structures
A Design Guide and Commentary
This book, Wood Structures: A Design Guide and Commentary, is intended to present significant research and development findings as related...

Pipeline Bridge Uses Timber Arches
An arch bridge is utilized for the purpose of providing a river crossing for a water supply pipe. Tidal influence, an unfavorable riverbed situation complicated by estuarial and other...

Full-Scale Tests on Tapered and Curved Glulam Beams
A series of full-scale tests, designed to evaluate the available theoretical analyses, were conducted on double-tapered, pitched, and curved glulam beam members. The Douglas-fir beams,...

Nonlinear Analysis of Unsymmetrically Laminated Plates
The nonlinear behavior of unsymmetric filamentary composite laminated plates is investigated. The simplifying reduced stiffness model is used to demonstrate its adequacy in predicting...

Layered Beam Analysis
Governing equations for layered Timoshenko beam theory for the general case of unsymmetrically stacked laminated beams are presented. A computer program is developed to use the theory...
