This paper presents the performance-based seismic design of a residential tall building located in Philippines. The project comprises a 55-story residential tower with 6 above-grade podium levels and 4 basement parking levels. The building is approximately 198.6 m tall above ground level. Reinforced concrete core wall and distributed outrigger system comprised of moment resisting frame beams are used as lateral load resisting system. Initially, the building was designed for gravity, strength level wind and Service Level Earthquake loading. Nonlinear design verification was carried out for Risk-targeted Maximum Considered Earthquake (MCER) that the shaking intensity which can lead collapse probability of 10% or less under 2475-year return period. using design information from initial design stage. Nonlinear response history analysis was conducted to check the global responses and local responses of structural components of building for Collapse Prevention structural performance level under MCER and design information of initial design stage was verified and adjusted.
