All steel design conforms to CSA-S16-14
Complete steel design is performed for post-and-beam connections. Steel design is not performed for lapped shear connections and nailed connections. The engineer is responsible for the steel design in these connections.
The following steel design checks are made for post and beam connections
Steel plates are checked for tension and shear.
Bearing plates are checked for bending
Bolts are checked for tension, shear, and bearing of bolt on plate
Washers are checked for bearing and bending
Weld size is determined by plate sizes, and required length is determined to resist load
Edge and end distances for steel plates are considered.
Calculation of steel thickness for bearing plates is based on the following: the applied load, whether it is two or three sided support, the width of the supported member and length of bearing needed for wood design.
Bearing plates are 3mm wider than the beam or purlin they are supporting.
Side plates must be at least 12 mm below the top of a purlin.
Face plates must be at least 12 mm below the top of a beam or girder except for top mount hangers.
Steel plates must be at least 6 mm from the edge of a column.
Steel plates covering shear plates extend 5mm beyond the edge of the shear plates.
Items such as steel design parameters and default plate sizing can be changed in the Initialization File. Please refer to this file for a complete list.
