due to lack of skilled workers in libya i have been entrusted by my boss to roof an area 20m by 40m. every 4m in the 40m length there is a concrete pillar.Since the span of the truss is gonna be 20m what should be the distance between the top chord and the bottom chord? What steel thickness should be used? thanks you in anticipation
