Description

Dear All,

As per IS 1893-2014 (part 4), clause 5, seismic combination has to be checked for SLS case with DBE (Design Basis EQ)& MCE for ULS. Can any one please explain me why this clause is introduce in this code. In 1893-Part1 there is no clause like this. We used DBE only for ULS design i.e., zone factor by 2 (Z/2).
As per IRC-6 Table 3.2 load combination, EQ force is not to be considered for SLS check.

Regards,
siddu
