Dear Rahul,

Regarding your second question, I feel that there is some problem in
Staadpro.As per 6.4.4. of 1893-2002, the reduction in value of the horz.
spectrum
is applicable only for the substructure.It is not valid for
superstructure.But staadpro calculates value of  VB ( for entire
structure)considering depth below gr. level.
If it is so it will substantially reduce the hor. load applied on all super
structure nodes.That is not the code wants to be.

Regards,
Sachin.

Dear friends, Please help me in these two queries.

1) If I want to model slab as a bracing member in analysis of bldg. , can
I take two members crossing each other? ie, if the slab panel is a square
one, can I take two members diagonally connecting and crossing each other?
Quote:

2) As per I.S.1893 2002 the part of the structure lying below the gr.
level has to be designed for a lower Vb compared to the super structure.Is
staadpro takes this point into consideration while working out time period
and Vb?
