Hi everyone,
I have one question regarding the amount of the reinforcement required in calculation.
Namely, I modeled the composite bridge structure using Wizard option in RM Bridge. For longitudinal reinforcement, wizard already defined the A1 reinforcement. After calculation, only in the element where
defined A1 reinforcement wasn't enough, the A2 reinforcement appeared as additional.
The thing I am curious about is how the software calculates that user-defined A1 reinfocement, in this case Wizard? How it chooses that specific value?
The following figure shows the amount of required reinforcement with A1 input of 17.69 cm2 (Wizard definition)
The next figure shows the amount of required reinforcement with A1 input of 5.33 cm2 (user-defined-me)
According to this, final amount of required reinforcement in slab at the ends of the beam is different depending on input A1 reinf.
Why this is happening? Did anyone had similar experience?
Thank you
