Abstract: In recent years, there has been an increased emphasis on the far-field effect of earthquake on buildings sited on soft soil due to the large amplifying effect on long distance earthquake waves by the soil. This problem is especially pertinent in countries like Singapore where buildings are designed according to non-seismic codes. It is necessary therefore, to examine the vulnerability of such gravity load designed (GLD) buildings to far-field earthquake action. In this study, the response of a GLD reinforced concrete frame found in typical low-rise buildings to lateral action was investigated analytically and experimentally. The analytical study provided a reasonable prediction of the response of the frame under pushover load. Using a glass FRP retrofit system, the strength and the ductility of the frame were increased by 29% and 75% respectively. It was also observed that the system delayed the formation and widening of the cracks in the frame member.
