kdef.c = 2 ■ (kdef.m ■ kdef.ply)0'5 kdef.c = 1-79

Deformation factor for the plywood, kdef,ply

(complies with BS EN 636: Part 2)

Deformation factor for the connection, kdef.c

(Complies with BS EN 636 Part 2) (equation 10.78 (EC5, 2.3.2.2 (4)))

Characteristic strength of each bolt /u.k = 400 N/mm2

3. Partial safety factors

Material factor for timber, yM Km = 1-3

Connection factor, KM.connection KM-connection = 1-3

Table 2.2 (UKNA to BS EN 1990:2002, Table NA.A1.1) - Category A

Factor for quasi-permanent value of f2 = 0.3 the variable action, f2

4. Modification factors

Factor for medium-duration and service class 2, £mod.med (Table 2.4 (EC5, Table 3.1))

5. Actions

Design loading on the beam, ib.d
