Civil Engineering/Moments



Please explain briefly  difference between in plane and out of plane moment in context to a Slab , Beam , Wall , Column , Bolt and Weld using simple concepts.

Dear Arsalan

Each body is subjected generally to 3 moments in each of its nodes. For a wall or a frame member you have 3 moments in each nodes. when you subject a wall to a force parallel to the plane of the wall,  a moment develops in the plane to withstand the force. When you lean against a wall the moment is developped in ortogonal plane. This is called an out of plane moment. The third moment is twisting which is not your problem here.
