In a 6-storey building under construction, the 4th floor beam concrete core results are 20 N/mm2. Project concrete class c30. The building is stopped by the building inspection. Do you think a performance analysis can be made in the building by predicting that C30 will be poured on the upper floors without breaking the beams on this floor? Or is the performance analysis only done for the currently completed buildings? Thanks in advance for your answers.
