Earthquake Forces & Concept of Ductility in Construction

17th - 18th August 2017 New Delhi & 21st - 22nd August 2017 Mumbai

Course Description

UNDERSTAND EARTHQUAKES & EARTHQUAKE FORCES USING CONCEPT OF DUCTILITY IN CONCRETE & STEEL STRUCTURES FOR ECONOMICAL BUT ROBUST DESIGN OF BUILDING & INDUSTRIAL STRUCTURES

For Buildings & Industrial Structures founded on weak soils, Elevated Water Tanks, Tall Structures like Chimney or Towers, use
of ductile detailing is a must. This workshop is planned to give a deeper insight into the requirement of ductile detailing so as to
make a suitable choice. Earthquakes are unpredictable and un-preventable major natural disasters. The earthquake not only causes
a loss of life and property but also shake the morale of the people. During an earthquake, ground motion occurs in a random
fashion both horizontally and vertically in all the direction radiating from the epicenter. The ground motion causes the structures
to vibrate and induce internal forces on them. Hence, structure in such an earthquake prone zones (As per IS 1893-2002 Part-I)
need to be suitably designed and detailed for ductility to ensure stability, strength, and serviceability with an acceptable level of safety
under seismic effects. The ductility of a structure is, in fact, one of the most important factors affecting its seismic performance. If
ductile members are used for forming a structure, the structure can under go large deformations before failure. This is beneficial to the
users of the structures, as in the case of overloading if the structure is to collapse, it will undergo large deformations before failure
and thus provides a warning to the occupants. This gives a notice to the occupants and provides sufficient time for taking preventive
measures. This will reduce the loss of life. Hence in this technical paper, more emphasis is given to the essential provisions of the
ductility requirements of Reinforced Concrete Buildings as per IS 13920: 1993.
