Q1: With reference to test A could you please specify the reference points for the output displacements (points A4a and A4b of the required results)?

  • A1: The displacements of the centre of each floor.

Q2: Could you please specify where the RC walls are placed on the building plan (side A or side D)?

  • A2 The walls are considered connected on Side D

Q3: With reference to the connection between the RC wall and the slab, is it a stiff brace with rotation released?

  • A3: The rotation is released, the only contribution of the wall is related to the horizontal movement of the slab (see Annex 2 "The linear model of the walls works in parallel to the flat slab part of the structure in resisting horizontal forces")

Q4: With reference to the Test B points 1) and 2) could you please clarify what do you mean with "damage state at the first punching"? Do you mean at the total loss of bearing load capacity of the first member achieving the punching or at the development of shear cracks due to punching?

  • A4: The request of "Lateral drift capacity of the structure, evaluated as the drift of the two floors at the first punching of a connection" means "provide the the drifts of the two floors in correspondence of the reaching of the maximum unbalanced moment in the first connection in the structure with a punching failure"

Q5: Lateral loads in test B1

  • A5: For test B the forces F2 imposed on the second floor slab where equal to twice the forces F1 on the first floor slab: F2 = 2 x F1

Q6: Gravity load distribution

  • A6: See attachment ‘Added Gravity Loads on Slab’ in the Blind Competition section

Q7: Test B1 and B2

  • A7: Experimental activity beyond test B1 is not included in the blind competition activities

Q8: Concrete testing results

  • A8: See attachment ‘Concrete Testing results’ in the Blind Competition section
