Hi,
Can you please look at my model because when I'm designing (checking provided rebar), the message shown as in picture attached. After changing the size for beam which is for beam 2...13 at ground floor until 400x600 is only can pass. It is weird because another beam except beam 14...17 is ok for size 200x400.please help me here...
Thanks,
Hafiz
The reason of different reinforcement:
Required reinforcement example results
Shear capacity for this beam \ section (according to EC2)
(compare with the shear in this beam -> ~750 kN)
THis is screen shot from RC Calculator (Expert). Available on french market year(s) ago.
Concrete shear capacity:
so considering this and covers you should use 400x600 beam with C30 material.
BTW: your model may give you wrong results because you have neglected instabilities of type 1 and 2.
You have to correct releases to get rid of instabilities.
I am attaching corrected model - some releases replaced by my release "fp1"
