A Quick Overview

Costly cities require efficient utilization of land and materials. The discovery of high-rise structures and Sky-scrapers led to innovative materials that can bring more material optimization in building construction. Composite structures are one of the advanced construction techniques in civil engineering using which most of the sky-scrapers across the world were built-up and being raised.

This course has been developed to provide students, engineers and technical managers with a broad, but comprehensive understanding of composite structures and designing techniques used in the industry.
Composite construction allows for efficient use of material in
comparison to the traditional steel or reinforced concrete
design. In comparison to the reinforced concrete construction,
composite construction enables rapid and lighter
construction. In comparison to steel construction, the major
advantage is that composite members are relatively less
slender and generally have a closed cross-section. Therefore,
local and global instabilities are less likely. With increasing
labor costs and shortening timelines, composite construction
is likely to gain more popularity in India. However, the
unavailability of professionals with expertise and experience
in composite construction may prove to be a bottle neck.
This twelve-week course will focus on analysis and design of
composite structural systems. The fundamental behavior of
such systems and their interaction with other elements will be
highlighted. A brief introduction will also be provided on the
current state-of-the practice in different parts of the world.
