But 7.3.11 says to ignore ignore stiffness of flat slab.�Code should be consistent with its provisions, one can be confused to use whether use flat slab system or not in those zones.

Subject: [E-CONF] clause 6.2.2.4_damping ratio



Clause 6.2.2.4 requires damping ratio of 2% for concrete. Design acceleration spectrum as per IS 1893-1_2016 is for 5% damping. Which spectrum shall be used for 2% damping as per IS 16700?

IS 1893-1_2002 was having multiplying factor for dampling other than 5%.
