Abstract

The construction sector is one of the largest greenhouse gas contributors in the world. The use of raw materials as building materials is the main cause of carbon emissions in the construction industry. The use of steel materials has become very popular because it can be associated with a number of qualities, including its extraordinary durability, resistance to pressure, and flexibility. This is the main cause of steel materials being used massively in construction projects. If this continues for a long time, it will result in increasingly severe global warming. Therefore, a very detailed analysis and calculation are needed regarding the relationship between steel weight, carbon content, and structural strength so that, in addition to being structurally strong, it can be efficient in weight and very minimal in the carbon value released during the work process and the life of the building. Tekla Structures software is one of the software programs that can be used for the above analysis needs, the ultimate goal of which is to reduce carbon emissions. Three (3) different cross-section sizes have been examined using structural analysis, and calculations have been made on the carbon content that can be optimized for the material: H 400.400.13.2, 350.350.10.16, and 300.300.10.15. This study has successfully determined that the column with the size H 300.300.10.15 produces a carbon mass of 629,288.00 kg. (kg CO2e). With the smallest carbon content value and the carbon presentation in the material of 66.23%, the column cross-section with the size H 300.300.10.15 is recommended for use as a column structure cross-section
