Influence Line Diagram for moving load analysis

 

Influence line diagrams for static load analysis

  ILD are drawn for a single unit concentrated load travelling on the span/ structure. In the following video, I tried to explain the application of concept of ILD to the analysis of static/moving loads other than unit load, other than concentrated loads, and for multiple loads.

Influence line diagrams for trusses using the ILDs of beams

 The following video is for the students of II year B. Tech (civil Engineering) Programme. The video details the procedure for drawing ILDs of simply supported trusses

       In the following video, I tried to explain the procedure for drawing ILDs for member forces in trusses in which the top and bottom panel points are not vertically in line. In such trusses, a small correction needs to be done in the ILD. There should not be an abrupt change in the ILD at the point or section where the loading does not appear directly. So, that abrupt change at non-loading panel points needs to be smoothened.

Application of ILDs for critical load analysis

Application of ILDs for static/ moving loads beyond single unit concentrated load

         ILD are drawn for a single unit concentrated load travelling on the span/ structure. In the following video, I tried to explain the application of concept of ILD to the analysis of static/moving loads other than unit load, other than concentrated loads, and for multiple loads.
