Purlins C Static Data Overview

This document provides static data for purlins type C including section properties, effective section properties, and distortional buckling stress. The table shows that as the purlin size increases from C100 to C300, the section area, second moment of area, and other properties increase, resulting in higher distortional buckling stresses and load-bearing capacities at serviceability and yield. Purlins C140, C180, and C210 have relatively high section moduli and are suitable for common applications.
