WebSep 9, 2024 · You have to take accidental bending into account for the column design but it is not usually done in a very precise manner since determining the moment at a "pin" connection is not easy. As a rule of thumb, some engineers will only stress the column to a maximum of 60 to 70% of code since accidental moment can quickly over-stress a steel … WebThis base connection is a pin connection. It has only one bolt going through a lapped type connection, but in this case the vertical member uses two plates rather than one as can be seen in the example immediately to the left. The two plates simply distribute the vertical load between the plates. The method of attachement to the foundation is ...
