Repaired Pitch-Cambered Glulam Beams

Journal of the Structural Division, 1981
Full-scale tests were conducted on two radially reinforced Douglas-fir beams. The two beams, each with a span of 30 ft., were tested only to initial failure prior to repairing. The two beams were repaired by radially reinforcing each by a different method. The radial reinforcing was similar to the field repair carried out on beams which fail in service.

Radial Stresses in Curved Glulam Beams

Journal of the Structural Division, 1980
A method for estimating the maximum radial tension and compression stresses in curved glulam beams of rectangular cross section is presented. The recommended precedure is based on a parametric study of beams representing a broad range of the key geometric variables and subject to pure bending and uniformly distributed loading.

Size effect of glulam beams in tension perpendicular to grain

Wood Science and Technology, 2006
The strength of wood is reduced when the stressed volume is increased. The phenomenon is termed size effect and is often explained as being stochastic in the sense that the probability of weak locations occurring in the wood increases with increased volume.

Failure behaviour and repair of delaminated glulam beams

Construction and Building Materials, 2017
Abstract This paper presents the results of an experimental study carried out with the following main purposes: (i) evaluate the effect of different types of delamination of straight glulam beams on their structural behavior up to failure; (ii) evaluate the effectiveness of repairing those beams after bending failure through the use of self-drilling ...

New constructions of glulam beams in Canada

2011
An optimized 24f glulam beam lay-up has been investigated with a series of laboratory testing and computer modeling. The basic ideas of these assessments are to increase the efficient use of timber resource in the glulam construction with integration of reliability based procedures to characterize the specified strengths for the glulam beams.

Curved and cambered glulam beams

1994
In this second part of the test series, creep and long-term strength of curved and cambered glue- laminated timber beams are studied under cyclically varying humidity conditions. The beams are loaded in such a way that the failure is caused by tension perpendicular-to-grain. A total of 24 beams were loaded under long term loading.

Properties of Bamboo–Wood Hybrid Glulam Beams

Forest Products Journal, 2012
ABSTRACT Bending and shear characteristics of bamboo–wood hybrid glulam (BWHG) beams were investigated to evaluate the possibility of using laminated bamboo lumber (LBL) as a lamstock for glulam beams in structural application. Moreover, two different resin types were also evaluated for bamboo–wood bond strength.

Lateral stability of continuous glulam beams

2011
This thesis presents the results of a theoretical and experimental study of the lateral buckling of straight beams of rectangular cross-section resting on columns, a type of structure commonly found in the roofing system of multi-bayed buildings. The structure is analyzed as a simply supported beam, uniformly loaded, restrained at one end against ...
