http://www.tboake.com/SSEF1/pin.shtml 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 ...
