Analisis Ketahanan Struktur atas Rumah Instan Sederhana Sehat dengan Perhitungan Beban Gempa di Upgrade 3 (Tiga) Lantai

Abstract

Simple Healthy Instant House (RISHA) is a residential building construction technology with precast modular components with a knock down system. Based on the structural endurance test certificate, RISHA has structural resistance to earthquake loads up to six zoning with reference to SNI 03-1726- 2002. This makes it possible to update the analysis with the latest SNI and apply it to 3-story buildings. This study aims to analyze the mass participation and natural vibration time of the structure based on ETABS and manual calculations, analyze the durability of the superstructure, convert column dimensions from RISHA profiles to ETABS, analyze the strength of the column and beam structures and the strength of the joints used. From the results of the mass participation analysis according to SNI 1726; 2019 it still meets the requirements, namely above 90%. For the basic shear force about the X and Y axes of 190.39 kN. The structural resistance of beams and columns refers to SNI 2847 2019 and SNI 7833;2019. The drifts between floors that occur due to earthquake loads have met the requirements because their value is smaller than the allowable drifts between floors. The resistance of the structural joints between RISHA panels has an ultimate compressive strength and ultimate shear strength which is smaller than the required compressive strength and nominal shear strength of RISHA panels. Thus the connection meets the requirements of SNI 1729; 2020.
