Prestressed
concrete is recognised
not only as a structural material,
but also an ingenious principle
and a unique construction
technology, making a lasting
impression in civil engineering
infrastructure of the twentieth
century. It is ideally suited
for applications involving
long and slender spans (bridges,
building floor systems and
shell structures), crack-free
construction (pressure vessels,
nuclear containments, water
tanks and pipes) and enhanced
resistance to fatigue loading
(railtrack sleepers, etc.).
Since
its introduction in the early
1930s, prestressed concrete
has evolved over the years
to meet the challenging demands
of increased durability and
strength, innovative systems
of prestressing, new methods
of analysis and design, new
applications and construction
technologies. There is also
an emerging need for structural
monitoring of existing and
new PSC structures. These
issues are of great relevance
to India, which is among the
first countries in the world,
following France, to recognise
and explore the potential
of prestressed concrete.
This
volume of Conference Proceedings
(“Trends in Prestressed
Concrete”, June 1-2,
2001, IIT Madras) provides
a collection of state-of-the-art
technical papers that deal
with recent developments in
prestressed concrete, particularly
in India. In addition to discussing
current trends, some papers
also dwell on the past, and
the promise that the future
holds. The papers have been
authored by leading academicians,
professionals and consultants,
who are active in prestressed
concrete design, construction
and research in India. The
papers are categorised under
the following themes:
- Materials
for Prestressed Concrete
- Analysis
& Design of Prestressed
Concrete Structures
- Prestressing
Systems, Experimental Studies
& Structural Monitoring
- Construction
Technologies & Case
Studies
In
addition to the above, a separate
section, comprising seven
keynote papers by leading
experts is included. These
papers provide an excellent
overview of the main theme
of the Conference, viz., ‘Trends
in Prestressed Concrete’.
