Abstract

With the implementation of a series of policies for sustainable development of China's \Sintering coal gangue porous brick is the use of solid waste gangue sintered a new wall materials, has a high compressive strength, energy-saving, environmental protection and many other advantages, has been widely promoted. Wenchuan earthquake, seismic shear capacity of masonry structure, overall damaged perforated brick masonry than sintered common brick masonry, however, show a greater brittle failure and repair, reinforcement is more difficult. Today how to improve seismic shear and ductility of perforated brick masonry, perforated brick masonry in earthquake zone has become a prerequisite. This article is in this context, the research level of reinforcement gangue porous brick masonry seismic shear behavior perforated brick masonry seismic shear horizontal reinforced in a more in-depth understanding and improve the performance of its ductility, as The better sintering gangue porous brick this new wall materials in the application and popularization of the earthquake zone, to provide the necessary experimental and theoretical basis. For this reason, in order to fully understand the sintering gangue porous brick, perforated brick masonry mechanical properties and the level of reinforcement perforated brick masonry seismic shear behavior, the paper mainly studies the following aspects: 1. Mechanical properties of coal gangue porous brick study, namely porous brick compressive and flexural strength test study analyzed the impact of its strength the porous brick on various cracks; important single brick flexural strength of the mechanical properties of its masonry and porous brick holes the presence of cross-section cut, the same intensity level of the porous brick flexural strength than sintered common brick there is a greater difference, for better evaluation of porous brick intensity level, it is recommended that the compressive strength and folding pressure ratio of the two indicators to determine the porous basic mechanical properties of the intensity level of the brick; perforated brick masonry, perforated brick masonry axial compressive strength test, perforated brick masonry shear strength test. Compressive failure characteristics and failure modes, combined with the expression masonry compressive strength at home and abroad, the main factors affecting masonry compressive strength analysis of perforated brick masonry and porous brick own characteristics, proposed perforated brick masonry compressive strength recommendations expression; analysis of perforated brick masonry shear failure characteristics and failure modes the pin key role for perforated brick masonry, and the combination of the main factors to consider our specification masonry shear strength formula proposed porous brick Shear Strength of recommendations expression; perforated brick masonry level reinforcement quasi-static force test research, analysis reinforced perforated brick masonry, perforated brick masonry and porous brick masonry same reinforcement ratio compressive stress combination of masonry under masonry failure characteristics and failure modes, and compared with the perforated brick masonry shear seismic performance analysis; analysis of reinforced perforated brick masonry compressive stress, horizontal reinforcement mechanism; shear strength theory, the working mechanism of the horizontal reinforcement and perforated brick masonry shear mechanism proposed reinforcement perforated brick masonry shear strength of recommendations expression; energy equivalence principle, perforated brick masonry and reinforcement collapse resistance, perforated brick masonry reinforced perforated brick masonry collapse resistance; 4. plastic damage model using the ABAQUS finite element software concrete reinforced walls MYQ-3 hysteresis analog and and quasi-static test results of comparative analysis of the the reinforced walls seismic shear behavior.
