Evaluasi Kekuatan Bangunan Eksisting Struktur Kayu Medan Club terhadap Peraturan Bangunan Kayu SNI 7973 – 2013

Abstract

As a construction material, wood was known and widely used before people became familiar with concrete and steel. The use of wood provided that it can safely withstand different working loads for a specified period of time. The Medan Club building is a cultural heritage of Japanese civilization which occupied Indonesia in the 19th century. This building gives us an understanding of the architectural styles and traditional construction techniques of Japanese society in the past. This research was conducted to evaluate the performance of structural components of iconic and historic buildings in the city of Medan which have been established since 1879. This research began with observations of the Medan Club building which is located on Jalan RA Kartini, Kelurahan Madras Hulu, Kecamatan Medan Polonia, Kota Medan, Provinsi Sumatera Utara. After that, the problem of structural components which visually failed was formulated, after which it was continued with collecting field data in the form of data on the wood material of the Medan Club building and data on the size of the Medan Club building. Then structural modeling and analysis was carried out in Robot Structural Analysis Professional 2024 software. Next, corrected reference design values were calculated based on SNI 7973-2013. After obtaining the corrected reference design values, an evaluation of the strength of the structural components of the Medan Club building is carried out. If failure occurs in the structural components of the Medan Club building, structural strengthening will be carried out. The Medan Club beam structural components experienced excessive deflection based on the SNI 7973-2013 timber structure building construction requirements, the deflection value that occurred was 39 mm ≥ 28.23 mm. The solution to the failure of a beam whose deflection exceeds the allowable deflection is to install a steel plate next to the beam, with a plate measuring 20 mm x 200 mm and connected with a Shear Connector with a diameter of 16 mm with a distance between shear connectors of 300 mm. Reinforcement with steel plates installed next to the timber beams reduces the deflection that occurs in the beam, so that the deflection value that occurs in the beam becomes 16 mm ≤ 28.3.
