This research focuses on the building with reinforcement concrete and has 60,2 meter of height above the ground (14 stories). This system of the slender building has dual system which has shear wall and column to restraint lateral earthquake. The analysis method of this research is comparing behavior buildings designed based on code and alternative design due to earthquake. The building is also designed under MCE level due to strong earthquake risk in Jakarta. For preliminary design, the building is designed based on prescriptive code. The optimization is conducted based on performance based design guidelines (PBD guidelines). In this case, the value of SNI 1726-2012 is larger than MCE level because the code requires minimum strength 0.85CsW. Moreover, the acceptance criteria of code still requires strength concept for all element of the building. The research objectives are to assess the effectiveness of PBD in establishing architectural feature of structural design. The result of this research is the building performance which is designed under MCE level achieves Life Safety. In this case, the design based on PBD has reduced 30% column size with rebar 1% for all columns.
