Table 5.2 Summary of limiting stresses needed for checking static strength
Note. The final column shows where the relevant formula may be found.
5.2 THE USE OF LIMITING STRESSES
In order to obtain a component’s calculated resistance, as required for
checking the limit state of static strength, a designer needs to know the
appropriate limiting stress to take. Table 5.2 lists the various kinds of
limiting stress that appear in later chapters. The derivation of those
needed in member design is explained in Sections 5.3 and 5.4. Those
which arise in the checking of joints are covered in Chapter 11.
5.3 LIMITING STRESSES BASED ON MATERIAL PROPERTIES
5.3.1 Derivation
The first three limiting stresses in Table 5.2 must be derived from the
quoted properties of the material and Table 5.3 gives suitable expressions
Table 5.3 Formulae for limiting stresses that depend on properties of member material
Note. f o ,f u =minimum values of 0.2% proof stress and tensile stress.
