Abstract
On September 28, 2018, earthquake of magnitude M = 7.4 hit Palu and Donggala region, Central Sulawesi, Indonesia. The earthquake caused intensity of MMI IX in several areas and was followed by massive tsunami and liquefaction in several locations. Record of earthquake data shows that there is significant vertical earthquake that caused major damage on buildings though they had been designed according to design codes set by the Indonesian National Standard. One of buildings damaged by wave of vertical earthquake is the rental low-cost housing flats in Lere, Palu. This building was constructed in 2010-2011 using precast system of structure, designed according to design code of SNI 1726-2002 (equivalent to UBC 1997) and tested its performance against earthquake according to ACI 374.1-05. Detail examination reveals that there is a very large vertical earthquake causing failure mechanism not covered by mechanism of design capacity as assumed in the design code. In the future, it is recommended to employ structural system in the form of precast walls connected using unbonded post-tensioned connection installed vertically. The connection is expected to overcome strong vertical earthquake. This paper presents development process of seismic design code that can be used to design high performance building against vertical earthquake. The first stage is to redesign housing flats Lere, Palu employing performance-based design criteria according to ACI ITG-5.2-09 (2009). In the second stage, the building performance against earthquake is tested in laboratory according to ACI ITG-5.1M-07, followed by the verification of design method using time history analysis based on test data (2020). In the final stage, the development and implementation of design standard will be conducted (2021).
