Boilermaker live load isn't in your code book?
i just wasn't sure if typically a factor would be included to accomodate more than the static weight of the people occupying the surface.
i need to design some brackets to support a truss and 30 boilermakers while replacing the boiler wall that supports the truss in normal service. They have installed scaffolding on top of the truss, and the superintendent will have no more than 30 people working from the scaffolding at one time...
