KON.005 - Timber structures

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 Europen Standard specifies test methods for the determination of the fundamental frequency, damping, unit point load deflection and acceleration of timber or wood based composite beams and flooring systems.

This European Standard gives a method for determining characteristic values of mechanical properties and density, for defined populations of visual grades and/or strength classes of machine graded structural timber. Additionally it covers the stages of sampling, testing, analysis and presentation of the data.
The standard provides methods to derive strength, stiffness and density properties for structural timber from tests with defect-free specimen.
The values determined in accordance with thi...view more

This European Standard specifies requirements, additional to those in EN 14081-1, for type testing of machine graded structural timber with rectangular cross-sections shaped by sawing, planing or other methods, and having deviations from the target sizes corresponding to EN 336. This includes requirements for strength grading machines.

This European Standard specifies requirements additional to those given in EN 14081-1 for factory production control of machine graded structural timber with rectangular cross-sections shaped by sawing, planing or other methods, and having deviations from the target sizes corresponding to EN 336.

This European Standard specifies the test methods for determining the long term behaviour of coated and uncoated dowel-type fasteners in load bearing timber structures (nails, staples, screws, dowels and bolts with nuts).

This document specifies methods for the determination of characteristic 5-percentile strength and density values as well as mean values for stiffness from test results for solid wood, fasteners, and wood-based products in the frame of initial type testing.
This document also gives methods for checking strength, density or stiffness properties in the frame of factory production control by variables. Sampling is not covered by this document, but reference is made to the relevant product standards...view more

This document specifies a method of strength grading tropical harwood visually for structural use. This method is only suitable for pieces of timber with rectangular cross'section that is constant along their length.

This European Standard establishes a system of strength classes for general use in design codes.
It gives characteristic strength and stiffness properties and density values for each class to which EN 14081-1 refers.
This standard is applicable to all softwood and hardwood timber for structural use.

This standard specifies the test method for determining the withdrawal capacity of fasteners which have been inserted into timber (solid timber, LVL and glued laminated timber).
The test method applies to all types of nails, screws and staples.

This standard specifies test methods for determining the strength and deformation characteristics of stapled joints in load-bearing timber structures.
The methods assess joints with members of timber (solid timber and glued laminated timber) or wood-based products in the combination proposed for use in service and using all types of staples up to 3 mm diameter for circular cross-section staples or 4 mm x 2 mm for rectangular or oval cross-section staples.
The methods determine load-slip charac...view more

This standard specifies the test method for determining the resistance of timber to the head pull through of timber fasteners.
In this standard 'timber' includes solid timber, glued laminated timber and wood-based products.
The test method applies to all types of nails, screws and staples.

This document specifies the requirements for cross laminated timber with rectangular cross-sections shaped by sawing, planning or other methods.
This document covers cross laminated timber, untreated or treated against biological attack.
This document does not cover timber treated by fire retardant products.

This European Standard specifies the test methods for determining the strength capacity and stiffness of joints made with punched metal plate fasteners in load bearing timber structures, being used to join two or more pieces of timber of the same thickness in the same plane. The properties measured are:
-   load-slip characteristics and maximum load resulting from the lateral resistance of the embedded projections, at various angles between the direction of the applied force and;
-   the axis of t...view more

EN 15497 sets out provisions regarding the performance characteristics for structural finger jointed timber with rectangular cross section for use in buildings and bridges. The use of structural finger jointed timber may be limited to certain service classes in some member states. It also lays down minimum production provisions and procedures for Assessment and Verification of Constancy of Performance for structural finger jointed timber. This European Standard is applicable to structural finger...view more

This European Standard lists the visual strength grades, species and sources of timber, and specifies the strength classes to which they are assigned, as documented in EN 338.

This European Standard specifies two classes of permitted deviations from target sizes for structural timber of softwood and hardwood species. It also specifies the moisture content to be used as a reference point for the measurement of sizes, and gives average values for changes in size due to changes in moisture content. It is applicable to sawn and prepared square-edged structural timber with parallel edges having sawn thicknesses or widths greater than 6 mm.

This European Standard sets the performance requirements of the following glued laminated products: - Glued laminated timber (glulam); - Glued solid timber; - Glulam with large finger joints; - Block glued glulam for use in buildings and bridges. It also lays down minimum production requirements, provisions for evaluation and attestation of conformity and marking of glued laminated products. This European Standard is applicable for glued laminated timber made of coniferous species listed in this...view more
