Experimental Study on the Bending Engineering Wood Enforced by Steel

Through an experimental study on engineering wood enforced by steel,this paper conducts a detailed analysis on the mechanism of the load carrying capacity of the enforced wood and the influence of the design parameters on the test piece on the basis of the features of the materials and phenomena.This study suggests that firstly,steel contributes to bending of the wood,which is closely related to steel ratio,the aspect ratio of the wood as well as the way it enforced;secondly,the bearing capacity of the enforced wood is proportional to steel ratio,which is better with a larger aspect ratio;thirdly,the pre-stressed wood owns a stronger bearing capacity.
