Seismic Performance Evaluation of Model of G+7 CRC Framed Structure
- Analysis of the G+7 CRC framed structure for the seismic load as per IS code
- To evaluate the seismic performance of model of a G+7 framed structure for a ground motion compatible to Zone-V spectrum
- Study of the damage pattern and suggestion for improvement
Bottom 4 storey square box section
Top three storey lipped channel section
Beam- lipped channel sections
Bracings – plain channel sections
Design checking : IS 801-draftFirst ever test in India of this magnitude carried out successfully on a shake table for cold rolled steel framed structure
Scaled model of G+7 storey structure
Shake table testing
Peak ground accelerations (PGA) corresponding to Zones II, III, IV and V as per IS:1893-2002 code for soft soil conditions
The input time history in terms of accelerations and displacements corresponding to 0.08g, 0.16g, 0.24g and 0.36g
Input time history for 0.36g
Spectrum corresponding to soft soil conditions
Spectrum corresponding to soft soil conditions
Displacement response at top for 0.36g
Acceleration response at top for 0.36g
Demonstrated that the overall performance of the scaled model is satisfactory
Response spectrum analysis
Dead and live load – IS:875 Part 1 &2
