Based On The Bidirectional Equal Ratio Loaded Of Masonry Strength Test Research

Block and mortar masonry structure is made of anisotropic composite materials. The ultimate bearing capacity of the masonry structure affected by many factors, including: bricks, mortar compressive strength and compressive strength of masonry building quality and other factors. "Masonry structure design code" in China refer to the uniaxial compressive strength of masonry. In practical engineering, the wall is often in composite shear stress, so the wall at the different stress path, the ultimate bearing capacity under different stress ratio is of great significance. In this paper, through the brick compressive strength test, the compressive strength of mortar test, nine brick shear test and finite element numerical simulation calculation to finish the work and conclusions are as follows:Through the bricks and mortar compressive strength test of the bricks and mortar compressive strength value, and combining with the stress-strain relationship curves of TongJi university, lay the foundation for the fourth chapter finite element numerical analysis.Through the experimental study on the bearing capacity of 4 walls pills found that wall under eccentric load, ultimate bearing capacity is smaller than the finite element numerical simulation of limit bearing capacity and the wall collapse destroyed.Through the finite element numerical simulation in different stress ratio are analyzed and calculated by different ash seam inclination of cases, the ultimate bearing capacity of the masonry wall piece, and draw the failure envelope under different ash seam dip Angle.
