Abstract


With the first \Masonry is the use of thermal insulation composite structure has great potential for development of new green energy-saving materials autoclaved aerated concrete block masonry. However, autoclaved aerated concrete is also mainly used for building envelope, rarely used as a load-bearing wall structure . In reference to the contents of this article , based on research at home and abroad , through the combination of thermal insulation masonry structures ( by the autoclaved aerated concrete masonry , self-compacting lightweight aggregate concrete beams , insulation mortar masonry composite structure formed ) basic mechanics experiment , theoretical analysis and ANSYS finite element simulation , mainly to do the work of the following aspects : ( a ) by having insulation properties of masonry mortar autoclaved aerated concrete masonry basic mechanical properties ( gray masonry seam between the horizontal tilt angle θ were 0 °, 22.5 °, 45 ° and 67.5 °), measured axial compressive strength of masonry , Poisson's ratio , compressive stress - strain curves and other basic mechanical properties, and compressive stress - strain curves made ??on the basis of thermal insulation mortar masonry masonry constitutive curve . ( 2 ) According to the basic theory of elastic foundation beam , in considering the angular displacement of the beam , the elastic modulus of masonry , structural columns compressive stiffness, ring beam flexural rigidity and structural columns and structural columns and masonry work in the case of coherent deduced masonry structure composed of a vertical axis under uniform load bearing capacity formula. ( 3 ) This chapter is mainly through the ANSYS finite element software for composite structures masonry insulation nonlinear finite element analysis of composite structures of different sizes in vertical uniform loads under simulated ; analysis of composite structures masonry bearing capacity, load displacement and crack failure modes and other features.
