Background
Traditional building structure is from great, construction process is loaded down with trivial details, and the consumption of non-renewable resources can be accelerated in a large amount of building material's use, causes the influence to the environment, and neotype building structure component can solve above-mentioned problem through the improvement. The steel has high strength, uniform material quality and flexible connection mode, but has poor stability and fire resistance.
The FRP material can meet the requirements of building structures on mechanical properties while saving resources and protecting the environment. In recent years, bamboo structures are gradually applied in China, the bamboo growth cycle is short, the dead weight is light, the strength loss at high temperature is small, the bamboo structures are renewable and easy to process, but the bamboo structures are limited in application in high-rise buildings and bridges due to the fact that the bearing capacity of columns of the bamboo structures is low, the strength is low, and the anisotropy is achieved. Therefore, the FRP section, the steel, the biomass material and the bamboo wood can be manufactured into a combined member, high bearing capacity can be obtained, and structural stability can be improved. In the combined column, FRP (fiber reinforced plastic) sections, biomass materials and steel are main compression members, a gypsum layer and a bamboo layer are arranged on the periphery of the combined column, the gypsum layer has good fire resistance and can be used as a fireproof material of the members, and the FRP plays a role in restraint, so that the mechanical property of the members is improved.
