Hi,
I am trying to model a prestressed beam. Should i use wire element or solid extrusion to create prestressing tendons? and also which procedure do you recommend to assign prestressing condition?
Your help will be highly appreciated.
Regardless the software, the more accurate you simulate the case, the more accurate the results you get, accordingly modeling tendons as solid is more accurate than wires especially in bonded per-stressed elements. But in this case, you have to model the anchorage system as solids also. n other hand wire element is much simpler and easier to model.
So, if you are modeling the whole structure you may use wire modeling, but if you are modeling a limited zone such as anchorage zone of coupling zone you may use solid element.
good luck
