Dear All,

As per IS 800-2007 Chapter 12, the additional load combinations in clause 12.2.3 need to be used alongwith Table 4 combinations.

Now this load comb. consideres 1.2 Dead load +0.5Live load +-2.5Earthquake loads

can anyone confirm about Dead load meaning ,

Its
1.  DL = Selfwt + Dead wt. + Equipment operating
orelse
2. DL = Selfwt + Dead wt. + Equipment empty


further to that , please talk about application of these combinations.

whether to apply to main framing members or to entire structure.

if it is need to apply to entire strutcure  , then the load combinations given in Table w.r.t. earthquake load will be ineffective.

please correct  me if i am worng.


really appriciate your help on this matter.

thank you
tukaram
