摘要
采用ABAQUS有限元程序,建立了预应力胶合竹木梁分析模型,从预应力值与预应力钢丝数量两方面,分析了影响预应力胶合竹木梁受弯性能的因素,指出预应力钢丝数量的合理增加可增强其抗弯刚度,预应力值对其抗弯刚度的影响不大。
Applying ABAQUS finite element program,the paper establishes prestressed gluing bamboo beam analysis model,explores factors influencing flexural performance of prestressed gluing bamboo beam from two aspects of prestressed value and prestressed steel quantity,and finally points out that rationally increasing prestressed steel quantity will strengthen its bending-resisting rigidity. In addition,the prestressed value has little impact upon its bending-resisting rigidity.
