1. Geometric properties

Bolt diameter, d

Area of bolt in tension,

Number of bolts per shear plane, nbolt

Number of shear planes in the connection, nsp

Bolting pattern:

Horizontal distance to the bolt a, x Vertical distance to bolt a, y

Thickness of side members, isteel Side member thickness coefficient, coef coef =

x = 90 mm y = 85 mm isteei = 12 mm ¿steel d coef = 1

Thickness of the timber member, t2

Depth of the timber member, h

Distance from the timber-loaded edge to the extreme bolt, he

2. Timber and bolt properties

Table 1.3, strength class C24 (BS EN 338:

Characteristic shear strength, fv.k Characteristic bearing strength, fc.90.k Characteristic density of the timber, pk Characteristic strength of a bolt, fu k

3. Partial safety factors

Material factor Connection factor

4. Modification factors

Factor for short-duration and service class 2 ^mod.short

5. Actions

Design vertical load at the connection, Vd

Design moment at the connection, Md

Design horizontal load at the connection, Hd

Radial distance from dowels to centre of rotation

Sum of squares of distances, D = sum(r2)

when coef equals 1 and hole tolerance < 0.1d the plate is a thick plate (10.3 (EC5, 8.2.3(1)))
