Abstract

Bangladesh has a long history of earthquakes and the largest one that occurred here is of 8.7 magnitudes Great Indian Earthquake. Several international researchers showed the possibility of large earthquake to occur in this area in near future, which will cause damages of infrastructures resulting in loss of human lives. It has been observed that most of the existing medium rise reinforced concrete (RC) buildings in the urban areas of Bangladesh have soft ground floor which have been designed without following proper seismic design code, hence do not full fill the demand strength required against an earthquake. These existing medium rise RC buildings with soft ground floor need to be retrofitted with a suitable technique. In this study the performance of Hysteretic Device (HYDE) system in a medium rise RC building selected from an urban area of Bangladesh is checked by SAP 2000v15 software. HYDE is a passive control system especially developed for soft storey seismic control of medium rise building structure. A nonlinear time history analysis is performed using three earthquake data developed from normalized acceleration response spectra to check the performance of HYDE. From the analysis, design HYDE force is achieved as 6300 kN. It has been observed from the generated HYDE curve that, the overall horizontal displacement against the seismic force is reduced from 0.176 m. to 0.035 m. Which means, by the application of HYDE system, 80% of displacement can be reduced.
