Deflection Checking - Canadian Code - Serviceability Envelope

Jason Hoel — Mon, 30 Jul 2018 23:32:31 GMT

I am hoping to use STAAD for beam design for a run of simple span beams with dead and live loads.

I currently can not get the program to stop designing for deflection based on factored loads.

I was strength design based on envelope 2 and deflections for envelope 1. Is this possible for Canadian Codes?
