These building materials have high energy consumption, high pollution, difficulty in degradation after disposal, poor thermal insulation performance, and earthquake resistance. Poor performance and other defects. In the current environment of developing a low-carbon economy, green, ecological, and environmentally friendly new building structural materials are the inevitable direction for the development of civil engineering science and technology. Bamboo is one of the current varieties of green and environmentally friendly materials.

Research shows that the compression failure mode of bamboo engineering materials is brittle failure including compression failure, decompression failure and splitting failure, so that the entire structure loses its bearing capacity. Due to the lack of side effects of ordinary bamboo, Due to the constraints, the excellent compressive properties of bamboo are often not effectively utilized.
钢管约束混凝土结构研究历史悠久，技术成熟，钢管对核心混凝土能够提供持续的环向约束力，使混凝土处于三向受压状态，提高其承载能力和变形能力，避免混凝土的脆性破坏，核心混凝土的存在也避免了钢管的内向屈曲，但混凝土存在自重大、能耗高等不足。The research on steel tube-constrained concrete structures has a long history and mature technology. Steel tubes can provide continuous circumferential restraint to the core concrete, putting the concrete in a three-way compressed state, improving its load-bearing capacity and deformation capacity, avoiding the brittle damage of the concrete, and increasing the core concrete's strength. The existence also avoids the inward buckling of the steel pipe, but the concrete has shortcomings such as heavy weight and high energy consumption.
