[0060] The embodiment of the method for determining the whole process horizontal bearing capacity of the safety and stability performance device of the ancient building brick column of the present invention comprises the following steps:
[0061] Step S1. Select an ancient building brick column and upper wooden roof truss structure, such as Figure 7 shown. Obtain the elastic modulus E of the block by using the rebound tester 1 =20000MPa, compressive strength fk 1 =5MPa, γ 1 =18KN / m 3 , the elastic modulus E of the masonry mortar is obtained by using the mortar penetrometer 2 =6000MPa, compressive strength fk 2 =1.2MPa, γ 2 =16KN / m 3 , use the same kind of blocks and mortar or mortar materials to masonry and carry out mechanical experiments, the friction coefficient μ between the blocks and the masonry mortar 1 =0.7 and the bond strength c=0.5 MPa. The material steel plate used to obtain the safety and stability performance of the ancient building brick column through...
