Abstract

The need for an earthquake-resistant building must be fulfilled, especially for areas with high levels of earthquake vulnerability, such Indonesia. Installing a shear wall-frame system is one of the strengthening strategies to withstand the lateral forces caused by the earthquake and to achieve satisfactory global seismic behavior of the concrete frame structure. This ongoing research aims to demonstrate the seismic performance of a low to mid -rise concrete frame building equipped with a shear wall-frame system in several configurations. The response of the structure is analyzed through a nonlinear static procedure. Using Seismostruct, FE package, the capacity curve was obtained as structural response subjected to incremental static loading up to collapse load. The output shows that the structure of a shear wall-frame system has a maximum base value of 19.7x103 kN, which is greater than the base sliding value in the non-retrofitted building structure, which is 15.2x103 kN. The obtained fragility curve shows a comparison of the probability of damage to the structures of retrofitted and non-retrofitted shear wall-frame system buildings.
