Abstract

The standardized bridge design aides in this publication are for superstructures manufactured with glued-laminated timber (glulam) that was pressure-treated with preservatives. Four superstructure types are included: two longitudinal (slab-type) deck systems and two transverse deck systems resting on either glulam or steel girders. Simple span designs for both single- and multiple-lane bridges that conform to the American Association of State Highway Transportation Officials (AASHTO)–Load and Resistance Factor Design (LRFD) bridge design specifications are included.
