The study and construction of structures that support
or withstand loads are the focus of the civil
engineering discipline of structural engineering.
Large non-building constructions and building design
are the most prevalent tasks for structural engineers.
Structural engineers are required to make sure that
their designs meet predetermined design
requirements based on either serviceability and
performance (e.g., building sway must not cause
discomfort to the inhabitants) or safety (e.g.,
buildings must not collapse without appropriate
notice). In order to prevent or lessen fatalities or
injuries, structural engineers make sure that buildings
and bridges are strong and stable enough to withstand
all relevant structural loads, such as gravity, wind,
snow, rain, seismic (earthquake), ground pressure,
temperature, and traffic. Additionally, they create
structures that are sufficiently rigid to prevent
deflection or excessive vibration.
An analysis and design of a G+4 commercial
building (hospital) have been attempted in this
article. For analysis and structural design, we have
chosen to use the Limit State Method. The design
complies with IS 456-2000. We keep in mind that
structural design should fulfil serviceability, which
restricts deflection and cracking to an acceptable
limit, as well as ultimate strength in flexure, shear,
compression, tension, and torsion created under a
certain system of loads.
