MATERIAL ALLOWABLE STRENGTH DATA
- The density figures quoted are lowest value. This WILL NOT be conservative from a weight estimation point of view.
- Down factored allowables must be used in the heat affected zone of welded structures. If not given on this data sheet for the material in question, then the LAA allowable should not be used and a relevant specific figure obtained elsewhere.
- The correct abbreviation for each quantity, in the applicable Data Source, is given.
Factors Affecting Design Allowables from Data Sources
- Material Shape and Form:- The thickness of a material can have a large effect on it’s allowable strength. The way in which it was formed (e.g. rolled or extruded) can also have an influence.
- Anisotropy:- The strength of some metals can vary dependent on the direction of the applied load, relative to the crystal structure (i.e. grain) of the metal.
- Heat Treatment:- Heat treatment or temper conditions can have a dramatic effect on the properties of metal alloys.
- Statistical Basis:- Design data is generated from large numbers of physical tests. The more samples tested, the higher the confidence that can be assigned to the figures obtained. The statistical basis of the data concerns the number of samples, and the way in which the resulting data is manipulated to obtain the design allowable. The three bases usually quoted are named A, B and S. The LAA design allowables are the lowest figure of all the bases quoted in the Data Source.
