Models for Concentrated Load Performance Assessment of Isotropic Wood Floor Sheathing
Publication: Journal of Structural Engineering
Volume 129, Issue 8
Abstract
An important information required in the determination of models for the concentrated load performance assessment of wood joist floor sheathings is the minimum width of sheathing (effective width) that can be considered to support the load. In this paper, a theoretical study of the effective width in bending of simply supported, fixed, and continuous one-way models of isotropic wood joist floor sheathings is reported. The effective width has been found to be directly proportional to the span, inversely proportional to the thickness and degree of fixity at the supports, and almost independent of the wood sheathing’s mechanical properties. An equation has been developed for calculating the effective width of the models. For the critical simply supported model, the upper and lower bounds of the effective width are 2.0 and 1.4 times the span, respectively. Based on the effective width, a criterion for determining when a fully supported isotropic sheathing reduces to a one- or two-way plate model and geometric models for the concentrated load performance assessment of isotropic wood floor sheathings are proposed.
