and the checks are performed in the most unfavourable loading conditions, for combined action,

in ultimate limit state, according to EC5 EN1995-1-1:2009, §6. The connections are designed

as bolted connections with metal plates according to EC5 EN1995-1-1:2009, §8.

Structural system for purlins

The purlins are designed as simply supported beams with span length L=4.500m the distance

between the trusses. They are loaded with a surface load of width L1=0.300m (purlin spacing).

The purlin axis has inclination α=25.46° with the vertical. The vertical loads (self weight,

snow, concentrated load) are decomposed in two components in the directions z-z P.cosα,

and y-y P.sinα, the wind load acts in the z-z direction.

1.6. Truss static analysis

Design for connections with reduced stiffness (factor 0.20)

The truss is designed as frame structure (EN1995-1-1 §5.4.1)

with reduced connection stiffness according to the above factor

The rafter and the tie are considered as continuous elements.

The truss is first solved for various unit load conditions,

and from them are computed the internal forces

for the various loading conditions and load combinations.

Number of nodes = 13, number of elements =21, supports 4

1.6.1. Static solutions for unit loads

Assumptions for the design of bolted connections

The design of connections is based on plastic analysis. The forces at the bolts

are all reaching the same limit value. The metal plate capacity is based on

plastic section modulus. The compressive design force is reduced to 0.50xFd
