6. 1. INTRODUCTION
Based on the Architectural plans, section & elevation received from
DUSIB DD-IV, R.P. Bagh, Delhi the proposed building is a dispensary
located GaliZamirWali, NawabGanj,Delhi. Topography of site as per site
plan is even and the natural ground level of site isconstant. In this brief

6. DESIGN PHILOSOPHY
a) Building has been analyzed for conventional loads, Structural
members/ componentincluding foundation, RCC slab, beams and
columns are designed for the dead, live & seismic loads. The beams and
columns frame arrangement and design has been done by using STAAD
PRO version V8i.
b) All the RCC columns of the building are supported on Raft
foundation. Foundation are typically designed for the reaction obtained
from predominant load case, byanalyzing on STAAD PRO
c) Serviceability & strength checks of foundation & members are
carried out as per IS 456: 2000 5

b) Brick wall load
i) 230mm Thk. Wall = 5kN/m Run/m height
Floor to floor height = 3.30m(Net Height) = 3.00-0.45 = 2.85m
Weight of Wall = 2.85 x 5.0 = 14.25 kN/m
ii) 115mm Thk. Wall = 2.75kN/m Run/m height
Floor to floor height = 3.30m(Net Height) = 3.00-0.45 = 2.85m
Weight of Wall = 2.85 x 2.75 = 7.838 kN/m
Say 7.85kN/m
