The Nonlinear Analysis Of Reinforced Masonry Shear Wall

Reinforced masonry shear wall structure as a new type of building structure system,the architecture has evolved from the traditional masonry structure, but better than onthe mechanical properties of masonry structures. Experienced nearly a hundred years ofevolution and development, this structure has become another important buildingstructures comparable to concrete structures. For reinforced masonry shear wall of thestructure while the setting of the corresponding specification. However, the structure ofsuch research is still not perfect.Through the wall under pressure by the shear failure modes and failure mechanismstudy analyzes the factors affecting the shear strength of reinforced masonry shear wall.Reinforced masonry shear wall stress characteristics of the constituent materials,constitutive analysis, the establishment of a reasonable model of the reinforced blockmasonry shear wall. On this basis, discuss the vertical stress, high aspect ratio, the groutconcrete strength four factors affect reinforced block masonry shear wall shear strength.Through the analysis: In the case of other conditions remain unchanged, the shearcapacity of the wall is not as vertical compressive stress increases, only1.0MPa~2.5MPa vertical stress increases in the range we can improve the wall the shear capacityof the body; aspect ratio of the shear strength of reinforced concrete block masonryshear wall, with the increase of the aspect ratio, the shear capacity of shear walldownward trend and stabilized in the range of1.0to1.5; concrete strength has littleeffect on the shear strength of reinforced masonry shear wall; Significantly improve therole of horizontal reinforcement ratio in the range of0.075%to0.15%, the levelreinforcement ratio of reinforced concrete block masonry shear wall shear capacity.
