A prize winning presentation on "TENSEGRITY architecture" under the topic of "SMART STRUCTURES" for 8 minutes on "BUILDOFEST 2017" Tensegrity, tensional integrity or floating compression is a structural principle based on the use of isolated components in compression inside a net of continuous tension, in such a way that the compressed members (usually bars or struts) do not touch each other and the prestressed tensioned members (usually cables or tendons) delineate the system spatially.

2. The term TENSEGRITY was coined
by Buckminster Fuller in the 1960s as
a portmanteau of "tensional integrity"

Tensegrity, tensional integrity or floating compression is
a structural principle based on the use of isolated components
in compression inside a net of continuous tension, in such a way that
the compressed members (usually bars or struts) do not touch each
other and the prestressed tensioned members (usually cables or
tendons) delineate the system spatially.

 TENSION MEMBERS  GAINS STIFFNESS  WHEN LOADED
 ABSENCE OF BENDING MOMENT FORCES ACT THROUGH MASS CENTER
 A LARGE STIFFNESS TO MASS RATIO CAN BE ACHIEVED  BY
INCREASING THE NUMBER OF TENSIONAL MEMBERS
 EFFICIENCY OF A STRUCTURE INCREASES  MINIMAL MASS DESIGN
 Tensegrity structures use longitudinal members arranged in a very
unusual pattern to achieve maximum strength with small mass.

10. Applications of tensegrity
structures is appropriate in
various areas of civil
engineering such as:
1)Roof structures
2)Bridges
3)Smart structures

11. The patented Telstar
Tensegrity roof concept is
employed, for twin peak
contour and the plan
configuration. It is more
like a cable dome
structure than to a
conventional roof
structure. Initial studies
for the design of
tensegrity grids were
carried out by Snelson,
but its applications were
limited.

14. Civil Engineering structures are mostly static. One of
the challenging functionality for Civil Engineering
structures is an active adaptation to changing
demands, such as load variations, temperature
variations, settlement of supports and damage
occurrence.
The concept of active structures involves structures
that include both static and active structural
elements. Adaptive structures are defined as
structures whose performance is controlled by a
system composed of sensors, actuators and a
computer that provides the ability to learn and
improve response to changing environments.
The system of Tensegrity structures gains the
potential to adapt to change in environments, so they
can be equipped with active control systems.MONTREAL BIOSPHERE

15. Cloud Nine is the
name Buckminster Fuller gave to
his proposed airborne
habitats created from
giant geodesic spheres, which
might be made to levitate by slightly
heating the air inside above the
ambient temperature.
