The Effectiveness of Performance Based Design to Establish Architectural Feature of Structural Design for Slender Building

Abstract

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.
