|

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
