DYNAMICS AND
NON-DESTRUCTIVE TESTING OF STRUCTURES
Vibration of
structures may occur due to natural calamities like earthquake, wind and
flood. Also ageing of civil infrastructure and rehabilitation of damaged
structures are becoming critical issues. These require an accurate
analysis of civil engineering system which can be achieved only through
static and dynamic testing on existing structures.
Non-Destructive
Testing (NDT) can be performed to predict the properties of materials in
structures with minimum cost and at the same time, leave the structures
undamaged. Commonly adopted NDT methods
have sound scientific basis. It has the ability to determine the
strength and durability of critical construction without damaging them
and the tests can be carried out on the site. These methods are used to
estimate the strength, uniformity, homogeneity of concrete, to assess
the quality control, to monitor changes in the structures. Hence
periodical maintenance and required repair work can be done in time.
The
workshop discussed various NDT methods and dynamic testing on
structures. Demonstration of NDT equipment was also arranged. About 150
participants including practicing engineers, faculty members and
students were benefited.
The workshop was inaugurated by
Dr.K. Muthumani,
Deputy Director, Structural Engineering Research Centre, Chennai and he
also delivered a lecture on “Dynamic and vibration Techniques”. A
special lecture on “NDT methods and its applications” was delivered by
Dr.N.Ganesan,
Professor and Head of Civil Engineering, National Institute of
Technology, Calicut. The chairman of the workshop Dr.K.Subramanian
covered “Dynamics of structures” and the co-ordinator,
Dr.V.G. Srisanthi delivered on “Vibration Control Systems and
Testing of Two Bay Five Storey RC Frame Under Dynamic Loading”. NDT equipment
including PUNDIT, Rebound Hammer, Winsor pin system etc., were
demonstrated by Mr.M.P. Muthuraj. The valedictory address was
given by Mr. Muralidharan of Dr. FIXIT Institute, Mumbai.
