Design Proposal for Hostel Building

Introduction
In the world of today, there is an increase in the population which has led to the decrease in the
horizontal coordination system. This is as a result of the large area availability per person. The adoption
of the vertical system of coordination has therefore been on the increase. The building analysis of the
proposed hostel has been done by the use of the software called ETABS.ETABS software is capable of
handling the largest as well as the most complex models of the buildings. This includes the analysis of
the nonlinear behaviour hence it became a tool of choice during the structural design of the proposed
model. The software can be used effectively in the analysis as well as the design of the structures of the
building like beams, slabs, columns, and the shear walls. Through this particular software, it is possible
to properly apply various materials of the construction to the structural members like reinforced
concrete, structural steel, reinforced concrete among others. ETABS automatically creates the self-
weight as well as the resultant gravity to the lateral loads. The recommended codes that were
considered during the design included the following: IS 456-2000, SP 16, IS 875- 1987 (Part I), IS 875-
1987 (Part II).
Objectives
 To provide a design proposal of the hostels for student in the university which is expected to
acclimatize and adjust accordingly to the requirements of the new environment.
 To enhance availability of convenient as well as safe location for the comrades with advanced
care facility.
 To ensure provision of the proper atmosphere for the interchange of thoughts, ideas as well as
conducive study.
 Reduction of the current crisis of accommodation within the university through provision of a
low energy design of hostel with sustainable environmental characteristics.
Methodology
There is an urgent need for hostel building which will accordingly accommodate dining hall, staying
rooms, kitchen hall, sports room (aerobic room, indoor games), staying rooms, visitors’ room,
dispensary, electric room, laundry and finally store rooms.
Hostel Building Geometry
The hostel building that has been proposed has an irregular plan. The stories height is anticipated to be,
H=3.2m in which all the stories will be of the same height. The proposed building of the hostel has three
stories. In fact it is four stories including the ground floor. The length of the hostel is approximately
66.23m with the width being 50.23m.The total area of the hostel is 3326.73 square metres. The building
is made up of the square columns with the cross sections (0.3x0.45), slab thickness of 150mm and
rectangular beam of the cross section of (0.23x0.3) m. The column size is constant for all the stories and
the beam size is constant for every storey
Structural Design

Details of the plan
The dimensions are given in m and the modeling of the 11 storey building has been done by the use of
the ETAB software while the generation of the plan is has been done by the use of the Archicard. The
height of each and every storey has been constantly been maintained at 3.2m in the entire structure
whose total height is 11.1m. As had been indicated previously the length of the hostel building is
basically 66.23 and the width of the hostel is 50.23m resulting into area coverage of 3326.73 square
meters. The design and the analysis
