3. ABSTRACT
Hospital building provides medical service to the people. The main purpose
of our project is to satisfies the medical needs of the people. In this project we
concerned about the Plan, Analysis and Design of Hospital building.‘GOOD
HEALTH IS ABOVE WEALTH’ so hospital is an essential thing for man happy
life. We have proposed to exceute our project at Pethappampatti. Our project
comprises of ground floor,first floor and second floor. Special arrangements have
been made for the emergency service and provide the fire safety,emergency exit for
the safety of public. In our project, consultant rooms are separately available for all
diseases. It consists of doctors to checking patients for multi-disease, health check-
up and surgical operations.
While planning this “HOSPITAL BUILDING” the following factors are consider
Physcology of patients,lightening,ventilation,orientation aesthectics plays a vital
role. The analysis is done by using software package “STADD Pro”. Limit state
method is adopted for the design of slabs,beams,columns,staircase, footing etc.,

49. CONCLUSION
• Thus we conclude the layout of our hospital building which satisfy the
functional requirement upto a great extend. The hospital building consists of
two storey building. It is designed to stage ground floor, first floor and second
floor . The building can accommodate 100 patients with all the standard
facilities in it.
• In this project, the action of load on the structure is calculated and
analysis is made using STADD.Pro software. The structural design has been
done by using the limit state method. The structural drawing and detailing are
prepared for the same.
• On taking this project we have learnt analysis and design of HOSPITAL
BUILDING at every stage like planning, analysing, and design, etc., and thus
we got an opportunity for expressing our ideas on the topic.
