Optimasi Design Rangka Ruang (Space Truss) Type Barrel Vaults Tahan Gempa berdasarkan SNI 1726:2019 pada Bentang Panjang

Abstract

Long span buildings are buildings that allow the use of column-free space as wide and as long as possible. In general, there are two types of large span buildings, namely simple large span and complex large span. In large span buildings, such as stadiums, workshops, meeting halls and others, one of the most commonly used is the space truss structure where the space truss uses pipes and their connections in the form of balls of the barrel baults type in optimizing the use of space trusses with a width of 192 m and a length of 120 m, with a height of 50 m. The barrel baults type will be developed into 7 models where the most optimum of the 7 models is taken. From the analysis results obtained the basic earthquake value (V) obtained in model 1 = 3142.501 kN, model 2 = 3566.82 kN, model 3 = 4233.43 kN, model 4 = 4116.19 kN, model 5 = 5058.02 kN, model 6 = 4881.18 kN and model 7 = 3411.49 kN. From the analysis results that have been obtained that model 1 has the smallest tonnage and the largest is in model 6 with a tonnage of 62.242% heavier than model 1.
