Desain Struktur Beton Bertulang Tahan Gempa Pada Gedung Bertingkat Pasar Mardika Ambon Dengan Sni-1726-2012 Dan Sni-2847-2013

Abstract

Mardika Market, Ambon City, Maluku Province has long been an important part of economic activity in Ambon City, this market is planned to be revitalized into a Modern Market with five floors which function as a buying and selling area so as to provide comfort and safety for visitors and sellers in the market. . The purpose of this research is to determine the type and magnitude of the parameters used and to design a performance-based earthquake resistant reinforced concrete structure using the Direct Displacement Based Design (DDBD) method. The revitalization of the Mardika Market Multi-storey Building is planned with a life safety performance target (ATC 40). The type and magnitude of the design earthquake strength parameters are calculated based on SNI-1726-2012 and the basic shear force according to the DDBD method. SAP 2000 Version 20.2.0 is used to simplify the process of structural modeling and structural analysis. detailing of the main structural elements using SNI-2847-2013 regarding requirements for structural concrete for buildings. In SNI-1726-2012 Article 14, the earthquake response is indicated by the probability of an earthquake occurring, namely 2% within 50 years or an earthquake with a return period of 500 years. Parameter of Acceleration Response Period 0.2 seconds (Sms) 1.292g and a period of 1 second (Sm1) 1.231g. Parameters Spectra Acceleration Period 0.2 seconds (Sds) 0.8616g and Period 1 second (Sd1) 0.8208g. The Mardika Market Structure is in the seismic design category D so that the building structure system is designed with a special moment-bearing reinforced concrete frame system (SRPMK), and the modeling category with multiple response spectrums. The basic shear force using the DDBD method for X direction: 75,079 tonnes and Y direction: 73,708 tonnes, maximum beam and column size respectively, beam 50/90, column 90/90 cm.
