ABSTRACT
Structural design is the primary aspect of civil engineering. The very basis of
construction of any building, residential house or dams, bridges, culverts, canals etc. is
designing.
The foremost basic in structural engineering is the design of simple basic components
and members of a building viz., Slabs, Beams, Columns and Footings. For their design, an
architectural design is prepared using the Auto CAD. In order to design them, it is important
to first obtain the plan of the particular building that is, positioning of the particular rooms
such that they serve their respective purpose and also suiting to the requirement and comfort
of the inhabitants. Thereby depending on the suitability; plan layout of beams and the
position of columns are fixed. Thereafter, the vertical loads are calculated namely the dead
load and live load from IS: 875.
In this project, the design of G+5 floors Hostel building is done according to the
Indian standards. IS456 has been used for the reinforcement design. IS 875 has been used for
the estimation of all the loads on the structure viz. Dead Load, Live Load, and Wind Load.
Once the loads are obtained, the slabs are designed. Designing of slabs depends upon whether
it is one-way or a two-way slab, the end conditions and the loading. The analysis and
designing of beams & columns are done by the “STAAD PRO” software tool. The footings
are designed manually, after completion of designing the detailed estimation has to be carried
out.
