备注

对一块喷涂复合材料-密布原竹组合楼板的抗弯性能进行了试验研究,通过观察各级荷载作用下组合楼板挠度发展情况,探讨组合楼板的破坏过程、破坏形式及破坏机理,考虑原竹与喷涂复合材料之间的组合效应,获得组合楼板的抗弯承载力,并得出组合板的荷载-挠度曲线以及原竹荷载-应变曲线.结果表明:这种组合楼板整体性能良好,原竹与喷涂复合材料之间具有很好的组合效应,能够提供较高的承载力.

Research is carried out about the bending properties of sprayed composite material-densely covered bamboo composite slab. By observing the deflection development of composite slab under various load levels, the bending capacity of composite slabs was presented with consideration of failure processes, failure mode and failure mechanism. At the same time, the combined effect between bamboo and sprayed composite material are considered. The load-deflection curves relationship of composite slabs and bamboo skeleton load - strain curves were obtained. The results showed the composite slabs had excellent overall performance, with a good combination effect between bamboo and sprayed composite material, providing higher carrying capacity.
