Creep in Timber Structures

Description

This book presents the current state of the art about creep in wood, timber and timber structures. It 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. Modelling of this interaction is a relatively recent development, with important applications in timber engineering, which will have consequences for national and international structural codes of practice. The book has been prepared by RILEM Technical Committee TC 112 'Creep in Timber Structures'. The importance of deflection requirements in design of timber structures is first explained, and basic knowledge of time-dependant deformations, creep and predictive models is reviewed. The next chapters discuss the sensitivity of creep to different environments, deformation kinetics, mechano-sorptive creep, time-dependent slip of joints and creep testing of wooden structural components. The last two chapters summarize the variation of moisture in timber and creep analysis of timber structures. Priority research needs are identified and an appendix reviews national building code creep factors.
