Figure 55 External forces on cheek-plates dimensions in mm All base-plate stiffeners should be designed so that the elastic limit is not exceeded to be consistent with Annex L.l 2 . Adopting a 15 mm thick plate and assuming this will be class 3 to be checked later , determine the depth required by considering the elastic modulus. Note It is assumed that the cheek-plates resist the applied moment without acting in conjunction with the base-plate, in other words, in isolation as opposed to an...

For clarity, the base has been designed to resist only a single set of design forces. In practice, it would generally need to be...

2.5 x 1.0x430 fb.Rd - J5- 796 NW This satisfies the Eurocode 3 requirement for bearing, but to avoid excessive hole deformation the NAD gives the following limit for the ultimate bearing stresses 0.85 430 275 lt -- 443.9 N mm2 Note This treatment of bearing stress in Eurocode 3 differs from that encountered in British Standard BS 5950 Part 1 1990'3. The values stated in Table 33 of the British Standard ensure that little bearing deformation will occur, and are therefore similar to the NAD...

Williot Mohr Diagram Method
Length of weld provided 120 241 187 91 This is more than adequate, satisfactory. The deflection of a truss with non-parallel booms may be found by hand calculations using a unit load , graphically using a Williot-Mohr diagram or by means of a computer analysis. In this case the deflections were found to be as follows
