EX 04 | ILD FOR TRAIN LOAD | SERIES OF LOAD | LOCATION OF MAXIMUM SHEAR FORCE & BENDING MOMENT | ILD

Influence Line Diagram (ILD) is a graphical representation of Variation of Functions like Reactions at Support, Shear Force and Bending Moment for Determinate as well as Indeterminate Structures. ILD is mostly used for the analysis of Trusses and Bridges where the loads are not steady or say moving loads.
Through this study, One can learn how to find out Maximum and Minimum Shear Force for given Loading as well as Bending Moment.

I don't understand how you get ordinates on the maximum bending moment 3.6,4.8,4.2 and 3.4 and also maximum shear ordinates 0.13,.0.23,0.3

Dear friend I used Similar triangle rule... For Bending moment.... Peak value 4.8 or say section BM ordinate value is as per derivation which is (L-x) *x/L After that as per location For left riangle use.... At 8 m value is 4.8 than at 6 m how much value??? Similarly for all ordinate, we can find values using similar triangles... Hope your query will resolve now

Thank you very much

[@KHENISIR]

Glad you like it.... Keep learning

[@sindhuduba3961]

Sir both delta v are negative how to knowing which load is taking at c

[@KHENISIR]

Dear Friend.... Its trial method We have to start from first or last load of given train load as trial When delta V value changes its sign i.e negative to positive or vice versa... We have to take that trial load on section Hope you understand...

[@anandkatam8150]

Sir what about absolute maximum bending moment how to find out sir

[@KHENISIR]

Dear Mr. Anand.... During calculation of Moving loads effect i.e. rolling or influence loading......while section or particular location on span doesn't known then Absolute moment is used.....it is at equidistant from resultant of loading and mid span of given beam......method for that is described in example of Influence Line Diagram playlist.....kindly visit kzbin.info/www/bejne/n6DHZ2p6Z7-SpqM Hope you got the solution of your doubt...

[@anandkatam8150]

@@KHENISIR sir please make video on castiglanos theorem on trusses sir I loved u r teaching

[@KHENISIR]

Sure...will do it later....once the method of analysis of Trusses will be over..thank you for suggesting a new topic...will do it surely in future

[@shivamchangela6902]

Sir apne ordinate ka calculation kese kiya

[@KHENISIR]

Dear Shivam Ordinate ke liye hume similar triangle use kiya hai Jese 5 distance pe agar 10 value hai to 3 distance pe kitani hogi Wese humein section pe ordinate ki value mil jati hai uske use karke sari ordinate value milati hai

€w toh 45 hona chaiye dusre case mai

[@KHENISIR]

Dear Vasu, Σw means total weight of Moving or Influence load In any case Total load is constant as given condition Hope Your doubt is resolved by this response
