Abstract
Several rental low-cost housing flats built under the program initiated by the Ministry of Public Works and Housing were among those affected by a strong earthquake on September 28, 2018, which was centered in the Palu Koro Fault in Central Sulawesi. One of the important characteristics of the Palu earthquake is the significant vertical earthquake acceleration. The structures of the affected housing flats were designed to be earthquake-resistant according design codes valid at the time of construction. The structural systems used on those buildings were varied including conventional reinforced concrete, precast concrete, or prestressed precast concrete. This paper presents the performance of the structure of rental housing flats in Palu area based on the results of a qualitative and quantitative survey conducted from October to December 2018 in 21 towers at 21 different locations. The study shows that the performance of the rental low-cost housing flat structures is good because design development and implementation fully complies with the requirements of design codes and construction specifications set by the Indonesian National Standard. However, in some areas where vertical earthquake is dominant, some buildings were severely damaged because the earthquake in the form of vertical wave as taken place in Palu is not covered in building design codes. Nevertheless, rental low-cost housing flats built by the Ministry of Public Works and Housing are seen to be performing quite well compared to other buildings around them. In addition, the use of precast technology in rental low-cost housing flat structures results in better performance compared to that of conventional system because of better quality control during construction.
