英文摘要： According to two kinds of adobe masonry buildings form of seismic reinforcement, to carry out the series of seismic performance test and numerical analysis computation of ferrocement mortar reinforced adobe wall .Through the experimental study on shear and compression resistance of unreinforcement adobe masonry and reinforcement adobe masonry with ferrocement mortar on double-sided on the wall.Analysis unreinforcement and reinforcement adobe masonry on shear resistance ,compressive strength and deformation capacity and failure modes. By the test study on seismic behavior of timber column and beam-adobe composite masonry wall reinforced with ferrocement mortar on both sides of I-shaped and U-shaped wall, comparative analysis of test adobe masonry lateral bearing capacity and deformation capacity and the connections between the transverse walls and longitudinal walls, and energy dissipation capacity of four types of adobe walls. By means of numerical calculation, study axial force ratio, aspect ratio and other factors affect the seismic performance of ferrocement mortar reinforced timber column and beam-adobe composite masonry wall, establish lateral bearing capacity calculation formula, put forward the reinforcement technology of concrete measures and requirements.
