Why is seismic engineering not widespread?
Not taught in engineering colleges
Pace of change.
First strong ground motion recorded was only recorded in the 1930s.
Seismic codes of the ‘60s, rather simplistic.
Rapid pace of research and availability of computers have added tremendous sophistication to the subject.
All this has happened in just one life time!!!!
Few working engineers outside Universities with the time or inclination to keep up to date.
Cannot be practised as from a recipe book as complex concepts and mathematics involved.
Why is seismic engineering not widespread?
Seismic Engineering very different from regular structural design
In regular structural engineering design such as for gravity and wind,
Check the stresses in members and determine acceptability by a basic criterion such as actual stress < permissible stress.
Not so straightforward in seismic design!!
In earthquakes, structures designed for only a fraction (fifth to a tenth) of the seismic forces they can be actually subjected to.
To ensure safety, the structure is to be specially detailed for ductility so that the structure can undergo large deformations without total collapse.
Workshops held with all universities and Polytechnic Cell of Gujarat to discuss introduction of earthquake engineering education.
Based on consensus report of the workshops, it was decided to change the syllabus to incorporate earthquake engineering.
Detailed study was undertaken to ensure that students were not overburdened- meant overhauling of obsolete topics.
Curricula formulated for all the programs for seismic engineering for Degree, Diploma and Master’s level programs again through workshops and discussions.
GoG issued a GR to change syllabus in civil
engineering colleges accordingly in Polytechnic
Colleges, Degree & Post-Graduate Colleges
Capacity Building at Education level – Gujarat Teacher Training Program –Short Term Courses
Training Teachers to teach new earthquake engineering syllabus and build a force of earthquake engineering experts in state
Teachers’ Training
13 courses of one week each for engineering teachers almost equivalent to a full semester program in earthquake engineering –
Courses to be offered twice each for convenience of faculty
Courses go online from July 2003 and to end by March 2004
About 80-120 engineering faculty of Gujarat degree and polytechnic colleges to be covered under this training program
