为得到木-混凝土组合梁弹性阶段弯曲变形的计算方法,基于钢-混凝土组合梁折减刚度法的研究思路,提出适用于木-混凝土组合梁挠度计算的修正折减刚度法,利用试验结果对此计算方法进行验证,并与钢-混凝土组合梁的折减刚度法进行对比。结果表明,相比钢-混凝土组合梁的折减刚度法,修正折减刚度法计算精度更高,能够较准确地反映木-混凝土组合梁的变形能力。当木-混凝土组合梁连接件单位长度刚度较大且跨度较大时,可以考虑采用折减刚度法近似计算木-混凝土组合梁挠度。

To obtain calculated method of timber-concrete composite beams in elastic bending deformation stage,based on reduction stiffness method of the steel-concrete composite beams,the calculated method of modified reduction stiffness method applied to timber-concrete composite beams was presented and was verified with experimental results,as well as compared with reduction stiffness method of steel-concrete composite beams. The results shows that compared with reduction stiffness method of the steel-concrete composite beams,the proposed modified reduction stiffness method is more accurate and can mo...
