The Research On The Basie Mechanical Behaviors Of Self-thermal-insulation Masonry Structure

By insulating masonry and of self-compacting lightweight aggregate concrete composite frame structures composed of insulation structure, the main process is masonry and construction method of constructional column and circle beam similar to, that is masonry insulation masonry insulation poured concrete frame after the completion of a new kind of load-bearing wall of energy saving. Insulation is made of aerated concrete bearing block of masonry (brick) and homemade formed by thermal insulation mortar for masonry, masonry structure as a whole to achieve a single objective of energy-saving wall material, realized the integration of structure and thermal insulation. Following on from this article since the basic mechanical properties of thermal insulation masonry and basic material impact on the strength of:1. Developed with aerated concrete masonry mortar for lightweight aggregate of waste thermal insulation. Through trial and error, determine insulation masonry mortar mix, and conducted research on the constitutive relations, the development of thermal insulation structure of compressive strength of masonry mortar of work, are true self thermal insulation requirements;2. Study on basic mechanical properties of thermal insulation block. Simulation constraints are made of full size test method for stress-strain through test and the test results of data processing, research, flexural strength and compressive strength of a block of stress-strain curve, gained constitutive equation of thermal insulation block, for the study of basic mechanical properties of thermal insulation masonry structure and finite element numerical analysis provides mechanical parameters;3. Study on basic mechanical properties of aerated concrete masonry. Mainly through the test method of its compressive strength, shear strength, young's modulus, Poisson's ratio and compressive stress-strain curves were studied, gained constitutive equation of thermal insulation masonry, from the theoretical analysis of thermal insulation composite wall of masonry and provide appropriate finite element numerical simulation of mechanical parameters;4. Using combination of finite element numerical simulation of three dimensional and two dimensional, behavior on thermal insulation masonry, simulation of deformation and failure mechanism analysis. Basic mechanics parameters by block and mortar materials, analysis and calculation of stress and strain distribution inside the masonry, calculation of bearing capacity of masonry insulation, peak stress and strain, elastic modulus and Poisson ratio and other important mechanical parameters, by comparison with experimental data, presented by block, masonry quality mortar strength reduction to reflect the impact of simulation methods. By analyzing the results compared with the test values, validation is based on basic mechanics parameters of thermal insulation masonry block and mortar finite element model of true reflect basic mechanics characteristics of thermal insulation masonry.
