Yeah i usually use the danish national version of the eurocode, it varries but L/400 is normal.

Yes, E and I are not set to a correct value. :D

Hi I tried the superposition principle, and it works great! The other one seems a bit complicated, but im guessing it works for when i do not have the equations from a book. Thank you.

Thank you. I will try it tomorrow, tonight i just started by adding more points, then it also becomes more precise depending on where i put the point load I have probably used or heard about it before, but i find it difficult to translate all the terms from danish to english. I wanted to...

Hi Thanks alot. I really appreciate your solutions. I have used your solution BA and it works great! I just really wanted to understand the programming part, thats why i kept asking, and i should have said that. IRstuff have made what i wanted initially, thanks. I dont quite understand the...

I looked at mathcad supports website and didnt get much info besides that they call "x" a range variable. I saw a similar post where he reached a solution, but i dont quite understand it. https://www.eng-tips.com/viewthread.cfm?qid=495784 It seems GregLocock is on the right track, i just dont...

Okay, i will try to explain the problem better. Im trying to compare x to a. x is vector, depending on how i define x it has around 45 values. If i put the pointload in the middle of the beam, around half of those x values are greater og equal to a and the other half is lower or equal to a. I...

Hi Im trying to calculate the bending moment and shear force depending on the distance x along the beam. I tried making "a" into another matrix but then its either not a scalar or it says the number of rows and collums isnt the same. I saw a similar problem on here but didnt quite...
