Ministry of Public Works and Settlement

Government of Republic of TurkeySpecification for Structures to be Built in Disaster Areas

- The storey drift, Δi , of any column or structural wall shall be determined by Eq.(6.19) as the difference of displacements between the two consecutive stories.Δi = di − di − 1 (6.19)

- The maximum value of storey drifts within a storey, (Δi)max , calculated by Eq.(6.19) for columns and structural walls of the i’th storey of a building for each earthquake direction shall satisfy the unfavourable one of the conditions given by Eqs.(6.20)

(Δi)max / hi ≤ 0.0035 (6.20a)

(Δi)max / hi ≤ 0.02 / R (6.20b)
