Timber structures — Cross laminated timber — Part 1: Component performance, production requirements and certification scheme

This document establishes the basic principles for component performance and minimum production requirements for cross laminated timber (CLT). This document also contains scheme requirements for conformance, as provided in Annex D. The document is applicable to CLT products which are manufactured from solid-sawn timber or wood based panels built up of at least three layers in which the grain of adjoining layers are at right angles to each other. This document provides CLT dimension tolerances; component requirements; performance criteria; production, testing and trade marking guidance; and minimum requirements for factory production control. This document is based on known species, species combination and/or wood based panel structural performance and bondability. CLT qualified in accordance with the provisions of this document are intended to resist the effects of moisture on structural performance as can occur due to construction delays or other conditions of similar severity. NOTE This document does not include how CLT is to be used and installed, as it will be detailed in ISO 16696-2.

Timber structures — Methods of test for evaluation of long-term performance — Part 1: Wood-based products in bending

This document gives methods of determination of duration of load and creep factors under bending actions at ambient temperatures for a defined population of structural timber products such as solid timber, LVL, OSB, plywood, particleboard, I-beams calculated from test values. It presents methods for a) determining the duration of load and creep factors for new timber products, b) establishing whether a previously defined set of duration of load and creep factors can be applied to a tested product, and c) an optional method for establishment of sensitivity of duration of load and creep factors to changes in environmental conditions. NOTE 1 This document is intended to apply to wood-based products for which a duration of load factor or a creep factor is used in design. NOTE 2 The effect of elevated temperature on the duration of load factor and creep factor that is derived using these methods for use with timber products can need additional consideration.

Timber structures — Design method for vibrational serviceability of timber floors

The design method provided in this document addresses vibration induced by walking action of occupants and covers the following timber floor systems: a) Light frame floors built with timber joists spaced at a distance of no more than 610 mm with a layer of structural wood-based subfloor that is connected to the joists using mechanical fasteners or adhesive. The area density of a bare light frame floors without a screed (topping) and ceiling is not greater than 25 kg/m2. Figure 1 shows such a light frame floor. b) Mass timber floors built with mass timber panels such as cross laminated timber (CLT). This document consists of three elements: a) a baseline vibrational serviceability design criterion for timber floors using fundamental natural frequency and 1 kN static point load deflection as the design parameters including two types of design criteria, coupled and decoupled criteria; b) equations for calculating the design parameters; c) guidelines for the design values of the physical and mechanical properties of floor components. The design method is based on the assumption that the floor system has a single span and simple support conditions.

Bamboo structures — Bamboo culms — Structural design

This document applies to the design of bamboo structures whose primary load bearing structure is made of round bamboo or shear panel systems in which the framing members are made from round bamboo. Except as indicated in Clause 12, this document applies to one- and two-storey residential, small commercial or institutional and light industrial buildings not exceeding 7 m in height. This document is concerned only with requirements for mechanical resistance, serviceability and durability of bamboo structures. This document permits an allowable load-bearing capacity design (ACD) and/or allowable stress design (ASD) approach for the design of bamboo structures. Allowable load-bearing capacity and allowable stress approaches may be used in combination in the same structure. This document additionally recognises design approaches based on partial safety factor design (PSFD) and/or load and resistance factor design (LRFD) methods (5.11.1), previous established experience (5.11.2), or documented ‘design by testing’ approaches (5.11.3). Other requirements, such as those concerning thermal or sound insulation, are not considered. Bamboo structures may require consideration of additional requirements beyond the scope of this document. Execution is covered to the extent that it impacts the quality of construction materials and products required to comply with the design requirements contained herein. This document provides a number of modification factors, designated Ci. These are empirically derived factors, based on best available engineering judgement, that are believed to be universally applicable to bamboo materials that are appropriate for building construction. Parameters affecting bamboo material performance are many and are addressed explicitly through the use of experimentally determined characteristic values of strength and stiffness. Annex A provides a summary of the bases upon which the provisions of this document were developed. This document does not apply to — structures made of engineered bamboo products such as glue-laminated bamboo, cross-laminated bamboo, oriented strand, or densified bamboo materials, — bamboo-reinforced materials where bamboo is not the primary load-bearing constituent. This includes bamboo-reinforced concrete, masonry and soil, or, — scaffold structures constructed with bamboo.

Timber structures — Glued laminated timber — Face and edge joint cleavage test

This document specifies methods of evaluating the effectiveness of glued laminated timber face and edge bonds within a manufacturing plant by cleaving of the glue line in both dry and wet conditions. It is not intended that it be used for initial type testing where cyclic delamination or block shear is preferred. It is based on the principle that, provided minimum wood failure percentages are met, then the bond strength exceeds the perpendicular to the grain tension strength of the under-lying substrate and therefore the bond is not the weak element limiting the integrity of a glulam assembly.

Timber structures — Testing of joints made with mechanical fasteners — Requirements for timber density

This document specifies a method based on density, for the selection of pieces of wood used in determining the strength and stiffness properties of joints between members of structural timber made with mechanical fasteners. It is intended to be used in conjunction with a test standard specifying a test method. It is assumed that the wood pieces are conditioned to the relevant conditions, that the wood density is normally distributed and that any deviations are reported. This document is applicable only to specimens of structural timber. NOTE It is emphasized that the wood density is only one of the properties that can influence the strength of a joint. Other relevant properties are, for example, growth-ring size and orientation, toughness and hardness.
