Hello,
I have done a beam analysis and the shear at the middle is excactly 0. When i use " SECTION 0.5 MEMB 1" the results are okay. That means in the output file "shear y" is 0 at position 0.5.
But when i use SECTION command with 2 or 3 positions the results are not correct. For example, i have use the command "SECTION 0.25 0.5 0.75 MEMB 1" for the same example. and i have got huge value for "shear y" at 0.5 position. But it should be 0.
Anyone knows what's the reason?
Thank you in advance
