Porous Brick Opening And Holes Layout Study

Industrial waste gangue porous brick with environmental protection, energy saving etc, accord with the need of sustainable development, and can be widely applied in multi-storey building bearing structure. Since since the advent of liaoning province construction by high attention. In order to popularize, application in this new wall materials, liaoning walling reform office organization staffing liaoning local standards in architectural application technology as the foundation, and had a lot of effective test. This article through to industrial waste gangue porous brick of compressive performance numerical simulation and theory analysis, relevant standards for porous brick compiling provides theory basis.A lot of testing research shows that the destruction of porous brick first is in the single brick vertical vertical ash seam is in cracks and compressive strength of the masonry below porous brick itself the compressive strength, which indicates that the porous brick intensity has not been fully utilized. Because of the lateral deformation of generally greater than the mortar brick masonry compression of the lateral deformation, after their mutual constraint, make brick produced inside tensile stress. So porous brick most purely crushed less. Today's porous brick research mostly during the test stage of its mechanical properties were discussed, the real root up from mechanics analysis of less, so this paper reference others results, from mechanics on trying to its structure design and mechanical properties and geometric shape optimization aspects of research, that produce porous brick accomplished already stress reasonable and guarantee environmental protection and energy saving.This research mainly in the following aspects:1.This paper using the finite element method of four types of typical of porous brick resistance of the semi-ellipse pressure learning performance is simulated. Through the simulation compressive failure process, obtained the corresponding deformation diagram and the stress distribution law, for the design and application of porous brick provides mechanics grounds.2.When porous brick masonry in pressure, the pressure of the vertical direction function expansion deformation, quite paper-cover surface by edgeunder tensile holes. Can be simplified into space problem planar problem, and one of the porous brick bearing performance is the most heavily affected holes. The problem of stress concentration Through theoretical analysis of various hole shape of different stress concentration phenomenon.3.Because of the lateral deformation of generally greater than the mortar brick masonry compression of the lateral deformation, after their mutual constraint, make brick produced inside tensile stress, porous brick is pulled bad. Through theoretical derivation is deduced, pull with masonry by the relationship between the pressure 4.Through theoretical analysis and fem simulation conclusion, selection of porous brick conclusion.Finally, the full text done the research work are summarized, and the future research work is prospected.
