Creep and Creep–Rupture Behavior of Wood-Based Structural Panels
This paper summarizes a cooperative research program between the USDA Forest Service, Forest Products Laboratory (FPL), in Madison, Wisconsin, and Forintek Canada Corp. in Vancouver, British Columbia, Canada. This research program provided detailed creep–rupture and some creep information for composite panel products. Commercially produced plywood, oriented strandboard (OSB), and minimally alig...
متن کاملCreep Behavior of Wood Plasticized by Moisture and Temperature
Moisture in wood acting as a plasticizer will strongly affect the wood’s viscoelastic properties. However, achieving the desired moisture content (MC) at elevated temperatures during creep tests is difficult. The aim of this study is to accurately and systematically investigate the creep behavior of birch wood at high temperatures. Experiments were conducted using a dynamic mechanical analyzer ...
متن کاملCreep of beams of wood and wood-based materials under transverse load
The paper presents the test results of beams made of chipboards, fibreboards, wood as per referenced items [1], [2], [3]. Adopting various rheological models, their behaviour in time under permanent load was described. The model testing of a box-section beam, with wooden flanges connected with continuous chipboard lacings, was described. It was found that the construction of beams made of unlim...
متن کاملLong-Term Bending Creep Behavior of Thin-Walled CFRP Tendon Pretensioned Spun Concrete Poles
This paper discusses the long-term behavior of a series of highly-loaded, spun concrete pole specimens prestressed with carbon fiber-reinforced polymer (CFRP) tendons, which were subjected to outdoor four-point bending creep tests since 1996 in the frame of collaboration with the Swiss precast concrete producer, SACAC (Società Anonima Cementi Armati Centrifugati). The 2 m span cylindrical beams...
متن کاملCreep Behavior of Borate-treated Strandboard: Effect of Zinc Borate Retention, Wood Species, and Load Level
Creep performance of zinc borate-treated strandboard from southern pine (Pinus taeda L.) and red oak (Quercus falcata) was investigated at 25°C temperature and 65% relative humidity. It was shown that the borate treatment had some signifi cant effect on creep defl ection of the test panels, and the effect varied with wood species. There was no signifi cant effect of creep loading on residual be...
