Mechanical Properties Of Concreteone-wayslabs With Bamboo Core Experimental Research And Analysis

To solve due to excessive use of reinforced concrete caused by the waste of resources, environmental pollution, which is a realistic issue, we propose the concept of "bamboo bamboo core reinforced concrete one-way slab" green floor, through simple processing treatment of the entire root bamboo, alternative reinforced bars are uniformly distributed in the plate, hollow floor by using the characteristics of hollowcylinder itself, to achieve the purpose of reducing the floor weight. And the bamboo distribution as a reinforcement to increase the overall performance, so as to realize the natural bambooribs all instead of-reinforced cast-in-place concrete slab. In this paper, according to thebamboo core bamboo reinforced concrete one-way slabs in the test roomdivided into two batches of pouring the six 1:1 full-scale model test, the test Models respectively to simulate uniform load and concentrate load bending process of destructive testing, and has carried on the analysis and calculation of the model test of flexural performance,to explore the flexural performance and applicable calculation method, mainly completed the following work:(2) of bamboo a bamboo core reinforced concrete one-way slab modelof bendin g test on the whole process, the plate of the cracking load, ultimate load. At the same time, also confirmed the bamboo bamboo core reinforced concrete one-way slab bending process for elastic stageand plastic stage of development. This paper discusses the bamboo bamboo core reinforced concrete one-way slab whole process of bendingmoment deflection curve, stress, strain and the develo pment regularityof cracks.(3) by using gb50010-2010 calculation bamboo bamboo core reinforcedconcrete one-way slabs in the normal use of Mcr<M<MU deflection value calculation an d comparison analysis showed that: the use of codefor design of concrete structures provide the method of bamboo bamboorib reinforced concrete one-way slab deflection; and in the actualu-se of the process, bamboo bamboo core reinfo rced concrete one-way slab normal use limit state moment value controlled by the test in theprocess of slab crack development, and should not be used gb50010-2010 calculation of crack width and spacing; through the experimental data, the backstepping, ultimate bending of serviceability limit state o-fa bamboo core bamboo reinforced concrete one-way slab.(4) combined with the concrete structure design code gb50010-2010 ofbamboo bamboo core reinforced concrete one-way slab cracking moment and ultimate m oment of analysis and calculation and verify by using reinforced concrete calcu lation of bearing force method as a bamboo core bamboo reinforced concrete one-way slab flexural design formula, and put forward the board design related structural measures and suggestions.
