为倡导绿色建筑，制成了用竹条做骨架、碳纤维做箍筋的一种经济环保的混凝土柱．针对该混凝土柱的轴心受压力学性能和延性，采用 ANSYS非线性有限元软件对其进行了模拟分析．通过软件分析表明：竹筋CFRP箍筋混凝土柱的承载力和延性均高于普通混凝土柱，CFRP箍筋提高了竹筋混凝土裂化后的承载能力；与钢筋混凝土柱相比，箍筋间距相同时配筋率为3％的竹筋 CFRP箍筋混凝土柱的承载力和延性分别是配筋率为2％的钢筋混凝土柱的1．03倍和1．02倍，是配筋率为3％的钢筋混凝土柱的0．93倍和0．89倍；在适筋范围内竹筋CFRP箍筋混凝土柱的抗压性能随箍筋间距的增大而降低．

To promote green building,we propose a kind of economic and environmental protection concrete column that it uses bamboo as a skeleton and carbon fiber as stirrups.In view of the axial compression per-formance and ductility of the concrete column,we use ANSYS nonlinear finite element software to carry on the simulation analysis.The software analysis showed that the bearing capacity and ductility of concrete columns reinforced by bamboo ribs and CFRP stirrups were higher than that of plain concrete columns.Compared with reinforced concrete column,the bearing capacity and ductility of short column reinforced by bamboo ribs and CFRP stirrups whose reinforcement ratio was 3% were reinforced concrete column that reinforcement ratio is 2% 1.03 times and 1.02 times and were reinforced concrete column whose reinforcement ratio was 3% 0.93 times and 0.89 times in the same stirrup spacing;the compression properties of bamboo ribs and CFRP stir-rups reinforced concrete column was decreased with stirrup spacing increasing within the scope of the optimum reinforcement.
