Bending Performance And Theoretical Analysis Of Composite Panels Of Bamboo-reinforced Concrete

Given that the advancement of building energy-saving renovation work and the industrialization of construction, green building materials have been proposed, green wall materials begin to be research and development. China is rich in bamboo resources, bamboo has short growth cycle, strong regeneration, the features of fast, good mechanical and thermal properties, as a structure material, is helpful to improve the utilization rate of bamboo resources. Composite panel of bamboo-reinforced concrete as a new green wall is using restructuring bamboo ribs instead of steel ribs as shear connectors in composite panel which satisfies the orientation of the development of green building materials and has a broad market application prospect.At present, research of bamboo reinforced concrete composite panel is in its infancy. The bending and thermal properties of composite panel are studied in this paper.(1)The equation of computation for deflection of elastic slender parallelogram panel hinged a set of edge bearing transverse uniform loads is derived by taking the deflection of expression as a single triangular series by Levy. Proven, the formula can be applied under the boundary conditions of the rectangular plate deflection and internal force calculation. Meanwhile, this paper presents an optimal algorithm for the equivalent elastic modulus, that is, considering various materials.(2) The finite element model of composite panel of bamboo-reinforced concrete is established. First of all, the finite element model is validated reliable. Second, because of the diversity of section combination in reality, the bending and thermal properties of composite panel are analyzed, find out the key factors.(3) Composite panels of ceramic bamboo-reinforced concrete are applied as walls of the demonstration project, and compared with autoclaved aerated concrete block walls, autoclaved lightweight concrete panels and composite sandwich panels with truss shear connectors. The results show that although composite panels of ceramic bamboo-reinforced concrete cost slightly tall, but their long life, short construction period and good thermal performance make their comprehensive benefit far higher than other three walls.
