Some useful construction tips to draw influence lines for truss members

This construction video is extracted from a lecture delivered by a construction professional. The video focuses on the importance of influence line for effective structural analysis as well as process for drawing influence lines for truss members.

This video exemplifies a truss bridge. The structure is undergoing a moving load. In order to design the structure flawlessly, the outcome of the moving load on each truss member should be determined.

Influence lines play an important role in designing beams and trusses applied in bridges & other structures where loads are transmitted across their span.

The influence lines demonstrate where a load will generate the utmost effect for any of the functions studied.The influence lines demonstrate where a load will generate the utmost effect for any of the functions studied.

The influence lines are applied even if the applied is not a unit load or if numerous loads are applied. To discover the consequence of any non-unit load on a structure, the ordinate results acquired by the influence line are multiplied by the magnitude of the actual load to be applied. The whole influence line can be scaled, or just the highest and smallest effects are accomplished along the line. The scaled highest and smallest belong to the critical magnitudes which should be designed for in the beam or truss.
