The traditional reinforced concrete building structure has large self weight and complex casting process, a large amount of building materials can cause excessive consumption of non-renewable resources, the environment is influenced, and the novel building structural member can solve the problems through improvement. The steel has high strength, uniform material quality and flexible connection mode, but has poor stability and fire resistance.
In recent years, bamboo structures are gradually applied in China, and the bamboo has the advantages of short growth period, light dead weight, small strength loss at high temperature, reproducibility and easiness in processing, but the bamboo structures are limited in application in high-rise buildings and bridges due to low bearing capacity, low strength and anisotropy of the bamboo structure columns. Therefore, the high strength and flexibility of steel materials in the bamboo-steel combined structure can be utilized, the defects of the diversity of the bamboo materials are overcome, and the overall strength of the member is improved. The bamboo-steel combination is a method capable of obtaining high bearing capacity and improving structural stability. In the bamboo-steel combined column, steel cylinders, bamboo and building regeneration waste are used as main compression members, steel hoops are made of thin-wall steel, the bamboo is restrained, the bamboo strips are wrapped on the outermost layer, the bamboo strips are restrained and attractive, and a layer of carbon fiber is arranged between the bamboo strips and the steel cylinders, so that the mechanical properties of the members can be enhanced, and the appearance is not affected.
