Fragility of Existing Building Structure Due to Floor Addition (Case: Grand Heaven Pluit Bulding Renovation, North Jakarta)

EasyChair Preprint 11724

Abstract

In earthquake-prone areas, it is important to choose the right structural system for the building to have high seismic performance. The structural system must be able to withstand lateral forces to anticipate structural damage that may be caused by earthquakes. The fragility curve is a tool that shows the probability of a structure exceeding its prescribed damage states (limit) due to earthquake intensity. The purpose of this study is to compare the seismic performance of multi-storey building structures before and after renovation of additional floors using fragility curves. The structure analysed is a funeral home in North Jakarta. The existing building has 8 floors before renovation and 10 floors after renovation. The existing structure utilises a combination of shear wall shear resistance system. Nonlinear static pushover analysis was performed using seismoStruct software to obtain capacity curves and spectra. The three methods used in determining the damage states were the HAZUS MH-MR, ATC-40, and maximum base shear methods. The probabilities obtained determine how likely the building is to experience structural failure.

Keyphrases: Pushover analysis, Seismic performance evaluation, capacity spectrum, fragility curve
