I have not pasted from anywhere, I write it by myself what I think there is some minor mistake but I am not able to rectify that. Yes, I am getting the answer but that's not the point. I should know what's the problem there.

Internal hinges are provided in a structure to reduce the statical indeterminacy of the structure. The bending moment at the internal hinge is always zero from either side. An internal hinge makes the structure more flexible. It allows the structure to move which reduces the reactive stresses. As fa...

but Scott at internal hinge moment from both sides is 0 where you are considering that

hey, Scott thanks for replying but still I am getting the same error.
I just want to assign a UDL of 10 on element 10 & 11

pattern Plain 1 Linear {
eleLoad -ele 10 -beamUniform -10
eleLoad -ele 11 -beamUniform -10
}
Error: expected integer but got "-type"
anyone..?

try using a different node number that doesn't start with zero

how to incorporate internal hinges in a beam at any location.? Is there a command for that? or with the help of zero-length element then how to assign moment 0 at that point We cannot assign in the restraint condition because that will make total moment 0 at that point but in the case of plastic hin...

This is the example of a 1 storey single bay frame subjected to lateral point loading at joint 3. At every node in this frame, I have assigned hinges now I have to convert this code into SWAY MECHANISM for the frame by changing all hinges with plastic hinges. So what are the steps required for that ...
