Download Creep in Timber Structures Book in PDF, ePub and Kindle
This book brings together up to date information from research and practice about the interaction between moisture changes and mechanical loading, which may lead to excessive deflections or joint movements in timber structures. It has important applications in timber engineering, and consequences for national and international structural codes of practice.

Download Modeling the Long-Term Behavior of Structural Timber Book in PDF, ePub and Kindle
Creep deformation influences the serviceability limit state as well as the ultimate limit state of timber structures. In order to consider this time-dependent behavior, creep coefficients and rheological models have been developed by various researchers. Comparing the rheological models, quite different temporal deformations are evaluated for a duration of load of 50 years. In order to find the model, which is most suitable to the situation in the region of Tubingen, South-West Germany, the existing deformations of several beams in roof structures in opened, protected but not heated buildings are measured. By loading the structure the elastic global stiffness of the particular element is determined. So creep coefficients can be evaluated, which should have been used by the engineer in order to get the existing deflection after 50 years. Within the region of Tubingen, on average a creep coefficient of 2.23 was found based on these measurements. However, the standard deviation of 0.97 is quite large. For the numerical evaluation of the time-dependent behavior Toratti's model is modified, so that it matches the measured deformations.

Download Appraisal and Repair of Timber Structures Book in PDF, ePub and Kindle
Timber is one of the oldest of man's building materials, but because the building scene today is dominated by concrete and steel, many designers are unfamiliar with the properties of timber and its structural vocabulary. This new book begins with an extended introduction to timber as a building material: its various forms and properties, its response to environmental conditions, and the Building Regulations relating to its use. It goes on to follow the general sequence of work, starting with the commission, and then dealing with the survey, the investigation and the appraisal.

Download Creep and Creep-rupture Behavior of Wood-based Structural Panels Book in PDF, ePub and Kindle
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 aligned waferboard were tested to identify nine mills (three for each product) that produced panels with a range of flexural creep performance. The three plywood, three OSB, and three waferboard products (nine products total, one from each mill) were then tested to provide information on their duration of load (DOL) and creep performance. Large panel specimens were subjected to both rampload and constant-load tests under one environmental condition. The constant-load results provided conventional or deterministic DOL factors that compared favorably with National Design Specifications recommended for adjusting lumber design strength properties under dry service conditions. Ramp-load specimen data generally indicated a lower rate of damage accumulation than did data for constant-load specimens. Creep tests at two low constant-load levels were also performed on large specimens under three environmental conditions for a 6-month period. Those results suggested that present deterministic creep factors in panel design practice might be acceptable for plywood under the influence of relatively severe conditions, for OSB in moderate conditions, and for waferboard in dry service environmental conditions.
