How about if one of the spans has a combination of uniform load and a concentrated load not located at the mid-span. How is the FEM calculated in this scenario?
Plz help me with this problem a type 3 post tensioned prestressed concrete beam of 10 M span The Beam is post tension is in 3 high tensile bar of 40mm diameter located at an effective depth of 700mm.The effective prestressing force in each bar after all losses is 600 kN. Given f=40 N/mm².f,= 1035 N/mm². E,= 200 kN/mm², E=28 kN/mm², com- pute the width of cracks in the tension zone if the service load moment at mid span is 1040 KN m,
It is the rotational stiffness(k) for fixed far end in a propped cantilever beam , from M=kθ, where M is the moment, θ is the slope and k is rotational stiffness which is equal to 4EI/L.
Thank You Sir. It helps very well in my Endsem

thanks the video is useful
Glad it was helpful! All the best
Sir can we take stiffness for fixed and intermediate support as I/L and for roller ,SS and hinged support as 3I/4l. Is these values are correct
Thanks
Sir is this method can be done in 18schem also?.....gotta clear this backlog subject...plz do reply
Sir in Distribution factor table why we take D in last video u don't take D
Sir why the I is different for all three span?
Sir kani s method start kab karr rahe hoo sir ?
Next set of videos will be on Kani's method, keep watching and sharing
Sir can we get classes for DSMS
From march i will be uploading steel structure videos, keep watching
@@structuralanalysisanddesign i am also very excited to see 🙈 waiting for your DSMS videos ..
Plz help me with this problem

Sorry Ramesh, currently I am not in touch with prestressed concrete subject, in future i will definitely try, thanks for watching
Slop and deflection method sir es topick ka video banaye sir
Or dam
Hello Slope deflection method is already uploaded
How comes 4EI/ L ???? ANY DERIVATION ??
It is the rotational stiffness(k) for fixed far end in a propped cantilever beam , from M=kθ, where M is the moment, θ is the slope and k is rotational stiffness which is equal to 4EI/L.
Although u could simply find k with I/L for fixed far ends
And 3/4×I/L for any other conditions
4:24 should be -9
