studi : Gedung Attic Showroom Surabaya Menggunakan Shear Wall

Abstract

The Surabaya Attic Showroom Building is a multi-storey building located in the city of Surabaya. Currently, the construction of multi-storey buildings is becoming a trend in line with the density of construction, in which the risk due to earthquakes also increases given the sudden earthquake. A shear wall structure was added to this building to assist the frame in resisting lateral forces. The construction of high-rise buildings must be balanced with an understanding of the structural system for earthquake-resistant buildings. To minimize infrastructure damage and increase in casualties due to the earthquake, the Surabaya Attic Showroom building was designed using a Special Moment Bearer Frame System (SRPMK) and Structural Walls. Frames in which the Structural components and joints resist bending, shear and axial forces. The moment frame and structural walls are designated as earthquake-resisting systems in this 12-storey Attic Showroom building. Earthquake loads are designed using a response spectrum that refers to SNI 1726 2019. Structural modeling and analysis uses the 2016 ETABS auxiliary program. The design of the reinforcement for the structure of beams, columns, and beam column relationships (HBK) is based on SNI 2847 2013. As for the design of structural wall reinforcement refers to SNI 2847 2019. Based on the results of analysis and design of structural beams, columns and walls that have been designed to have earthquake resistance. The earthquake resistance can be seen from the fulfillment of the Strong Column Weak Beam condition, namely ΣMnc ≥ 1,2 ΣMnb. The nominal base shear load due to the effect of the design earthquake that is borne by the shear walls holds 74.6016%, and the frame holds 25.3984%
