ABSTRACT

The primary objective of this research is to thoroughly assess and analyze the susceptibility of fragile existing buildings in the residential region of Jabal Al-Taj, Amman, Jordan, to seismic hazards. To achieve this task, it was required to identify and classify the typologies of vulnerable buildings prevalent in the study area, evaluate the structural vulnerabilities of these buildings to seismic forces, and implement a risk assessment methodology to estimate potential damage and losses associated with seismic events. This was accomplished by conducting field surveys, data collection, structural analysis of selected representative buildings, and evaluating the performance under seismic loads. Design response spectra curves were created for soil profiles rock (SB), soft rock and stiff soil (SC) for different return durations of 2475, 975, and 475 years. The results obtained from these curves show that both the Uniform Building Code (UBC) and the Jordan National Building Code (JBC) underestimate the seismic hazard in this region. The structural investigations of an existing four-storey building revealed its columns and frames are insufficiently resistant to earthquake loads, with a drift-to-height ratio of 0.024 surpassing the limiting value of 0.02 as specified by the UBC and (JBC) codes. The results confirm the need to take the necessary action to protect these old buildings by performing suitable strengthening, retrofitting, or rehabilitating techniques to increase their earthquake resistance.
