Dear Mr Sidhu

It is true that welded joints do not allow free and full rotation of members in the physical sense. But it is basically controlling the structural behaviour by modeling the members to transmit only axial forces and under this constraint evaluate the forces and reactions in the truss. This way of modeling is used in other situations such as modeling columns for no-torsion condition(to be amenable to currently available design methods), or finite element modeling, though a structure may be essentially a continuous medium. Under such conditions very little moments, if any, will be developed in members and can be safely ignored.

However if required a trial-and-error procedure may be adopted using partial fixity facility available in most reputed analysis software.

Regards

J.Y.Desai

Dear SEFIANS



In truss design, it is assumed that the Joints are Pinned hence designed for axial forces. But in real practice the joints are welded.  How should such change be incorporated in design.
