Pushover Analysis of 10-Floors Reinforced Concrete Building (Case study: Mahkota Majolelo Sati Bautique Hotel)

Abstract

Abstract Analysis of nonlinear pushover (push load) is one component of performance based design that can be used as a means of determining the capacity of a structure. The analysis is carried out by giving a static lateral load pattern to the structure whose value is increased gradually until a displacement target is reached or until the structure collapses. The purpose of this study is to determine the performance level of the building structure of the MahkotaMajolelo Sati Bautique Hotel according to the ATC-40 document. The capacity curve can estimate the basic shear force and maximum deformation that occurs in the structure. The results of the pushover analysis can show the pattern of collapse and the scheme of the occurrence of plastic hinges in the structure when given loading. By looking at the scheme of the occurrence of plastic hinges, then it can be seen the critical parts of the structure of the Majolelo Sati Bautique Hotel Mahkota Building. Pushover analysis is carried out by referring to the new regulations in effect in Indonesia, namely SNI 1726-2019, SNI 1727-2013 and SNI 2847-2019. The performance point is obtained by using the FEMA 440 Equivalent Linearization method, which is a simplification of the capacity spectrum method. The determination of the performance level of the structure follows the ATC-40 document.
