ASSIGNMENT #6 CASE 2 Purlin Design
The figure shown has trusses 5.5m
apart with midpoint sag rods and
Purlins spaced 2.5m on center. The
roof truss is inclined 1 vertical to 2
horizontal. The weight of roofing
materials is 0.8 kPa, wind load is
0.7 kPa perpendicular to the roof
surface, minimum roof live load is
0.6 kPa. Design a channel section of
steel Fy
= 345 mPa, for the purlins.
Use LRFD and ASD of NSCP 2015.
The shown is a beam-column connection. Assuming normal weight concrete, f'c = 5000 psi, fy = 60
ksi and all the steel bars are uncoated. The top tension bars are # 9 bars and the bottom
compression bars are # 8 bars.

A floor joist consists of a 2" x 10" No. 2 Southern Pine
(Fa = 800 psi). The joists are spaced at 24" on center.
The beam is subjected to a dead load of 20 lb/ft
including beam weight and a live load of 60 lb/ft. If the
length of the beam is 14 ft, determine the actual stress
due to the loads on the beam, and if the section is
adequate for the loads being carried.
