Studi Alternatif Perencanaan Rsu Melati Malang menggunakan baja komposit Dengan Metode Lrfd

Abstract

RSU Melati Malang Hospital Building to assist the government in preparing health facilities in Malang City, with a building length of 27 m, a building width of 13 m, and a building height of 21 m which has a total of 5 floors and a roof floor. The structure of the building uses a composite steel structure. The author plans to use Steel Structures with the LRFD (Load and Resistance Factor Design) Method, a structure consisting of two or more materials with different properties and characteristics that work together to carry loads acting on a structure without neglecting the safety factor and function of the building. Composite structures assume that steel and concrete work together to carry the applied load so that the resulting profile design will be more economical. (Zakia,Warsito, and Suprapto 2019). To achieve safe structural conditions, all loading components must be planned properlyso that the design strength exceeds the resulting load. Rokhmawati, Azizah, Ulva Azizah Azzuhro (2022). The planning standards used are SNI 1727:2013, SNI 2847:2013, SNI 1726:2019, SNI 03-1729-2002. The results of calculating the 125 mm slab thickness, the joists use the WF 300.200.9.14 profile; main beam using WF 400.300.8.13 profile; The dimensions of the composite column using the WF profile 500.200.11.19 are wrapped in a 60 cm x 60 cm concrete column with Pumax = 134359.64 kg and Mmax = 95682.04 kgm. The reinforcement used is 4 Ø 16 as longitudinal reinforcement and Ø 10-250 as stirrup reinforcement. The dimensions of the foundation are Ø40 cm with 4 piles in 1 foundation with a distance of 150 cm between the piles and a pile depth of 22.80 m. The pile foundation is used with a foundation poer size of 3 m x 3 m. For foundation reinforcement, 10-D22 mm main reinforcement and D12-100 mm spiral reinforcement are used.
