Analysis & Design of Main Beams
loads acting on main beams are self weight, loads
from slabs and weight of wall. The main beams
were analyzed by two cycle
moment distribution method and designed
by limit state method.
& Design of Columns
The load acting on the columns are these transferred
by beams and self weight. The frames were analyzed
by two cycle momet distribution
method and designed for axial loads and
bending moments using SP16.
& Design of Footings
The footings were proportioned so that the bearing
pressure does not exceed the safe bearing capacity
of the soil. The bending moments and shears were
determined at critical sections and the footings
as isolated footing were designed by limit
Analysis of Frames
Multi storied frames have high degree of static
and kinematic indeterminacy. A rigorous analysis
of such frames consume considerable resources,
time and effort. Hence the building codes allow
approximate methods based on many simplifications
and assumptions, there by affecting a compromise
between the expenses, time and effort incurred
in performing a rigorous analysis and the savings
resulting there from.
cycle moment distribution method
is used to analyse frames. It is an approximate
method based on the assumptions that transfer
of moments does not take place from floor to floor.
The method gives sufficiently accurate results
due to the fact that moments carried from floor
to floor through columns are small compared t
The analysis of multi story frame is done by considering
one floor at a time. Each floor is taken with
column above and below and maintain and shears
are calculated in beams and columns.
Analysis for Wind Loads
loads acting to the building are taken into consideration.
Analysis for wind loads are done using portal
frame method and the loads are calculated
using IS 875 (Part 3) 1987.
Analysis for Earthquake Loads
effects are considered. Load calculations are
done by seismic coefficient
method using IS 1893-1984.
Analysis is done by portal
