竹筋混凝土梁工作性能研究

Research on Working Performance of Bamboo-Reinforced Concrete Beam

以竹筋代替钢筋的竹筋混凝土受弯构件既能够减少建筑行业对钢材的需求,又能够减少碳排放。文章通过综合因素折减系数法给出了胶合竹抗拉强度设计值的推荐值。通过已有试验数据,分析了竹筋与混凝土粘结与锚固、竹筋混凝土梁受弯性能。结果表明,适当提高配筋率能够有效提高竹筋混凝土梁的受弯承载力。文章认为,竹筋混凝土梁能够满足低地震烈度区域单层或多层住宅建筑的承载力要求。

Bamboo-reinforced concrete flexural members with bamboo reinforcement instead of steel bars can not only reduce the demand for steel in the construction industry, but also reduce carbon emissions. This paper gives the recommended tensile strength design value of glued laminated bamboo through reduction coefficient method. Based on existing test data, this paper analyses the bonding and anchoring performance between bamboo and concrete and the flexural performance of bamboo-reinforced concrete beam. The results show that the flexural bearing capacity of bamboo reinforced concrete beam can be increased effectively by appropriately increasing the reinforcement ratio. This paper believes that bamboo-reinforced concrete beams can meet the requirements of single-storey or multi-storey residential buildings in areas with low seismic intensity.
