Just like regular warehouse metal building design, the end wall is often framed by wide flange steel column and rafter and rafter is often bolted to top of column. cold form Z purling is bolted to top of rafter. When wind hits the end wall, because of free span of column, half of the wind load...
I am a new on metal building design and want to know followings:
1. The rafter is often connected to top of column.
2. The purlin is rigidly connected to rafter.
3. How will the concentrated load on top be transferred to roof diaphragm? by rotation of rafter? how to check the strength of rafter?
