The practical study of steel-wood composite column in light and low-carbon building

Abstract

Steel improves the safety performance of buildings, but also greatly increases the carbon emissions of buildings, which is not conducive to environmental development. Based on the consideration of reducing building carbon emissions, this study proposes to replace the pure steel load-bearing column in the low-rise building with a new load-bearing column in the form of steel-wood combination, and establishes a theoretical and numerical model to explore its reasonable combination size to verify the safety of the structure in practical applications. And the carbon emission assessment and analysis of the whole life cycle. It is found that the steel and wood structure can replace the pure steel structure of the corresponding size in the low-rise building, which greatly reduces the carbon emissions of the building while achieving structural safety.
