摘要

竹集成材是一种融入了现代加工技术且强质比高、环保美观的工程复合材料。为研究剪跨比对侧压竹集成材梁受剪承载力的影响，设计了剪跨比分别为0.75、1.0、1.5、2.0和2.5的5组（每组3根）竹集成材梁进行四点弯曲试验，研究侧压竹集成材梁在荷载作用下的变形特征、破坏形式及剪跨比的影响规律，探究竹集成材梁抗剪性能的影响因素及其承载能力的计算方法。结果表明，竹集成材梁具有较高的承载力和刚度；其受剪承载力与剪跨比有关；当剪跨比小于1.5时，发生层间剪切破坏，而大于等于1.5时，发生弯曲破坏。提出了竹集成材梁的受弯承载力、受剪承载力和弹性变形计算公式，计算结果与实测值吻合较好。

Abstract

Bamboo composite is a kind of engineering composite bamboo with modern processing technology

high strength and quality ratio

environmental protection and beautiful appearance. In order to study the influence of shear-span ratio on the shear capacity of side-loaded bamboo-integrated beams

five groups of three beams in each group with shear-span ratio of 0.75

1.0

1.5

2.0 and 2.5 were designed to carry out four-point bending tests. The deformation characteristics

failure modes and the influence of shear-span ratio of side-loaded bamboo-integrated beams were studied. The influencing factors of shear performance and the calculation method of bearing capacity of bamboo composite beams were studied. The results show that the bamboo composite beams have higher bearing capacity and stiffness

and the shear capacity is related to the ratio of shear span. When the shear span ratio is less than 1.5

interlaminar shear failure occurs

while when the shear span ratio is greater than or equal to 1.5

bending failure occurs. The formulas for calculating the flexural bearing capacity

shear bearing capacity and elastic deformation of bamboo composite beams are put forward

which is in good agreement with the measured values.
