Influence of Infill Wall Configuration on Failure Modes of RC Frames

Table 5

Shear bearing capacity ratio of the frame column to the infill wall (ξ).

Masonry strength; (MPa)	(kN)	(kN)		Short column failure
2	225	111.7	2.01	No
2.5	225	139.7	1.61	Yes
3	225	167.6	1.34	Yes

According to the literature [23], + , where λ is the shear span ratio, b is the width of the column, h0 is the effective height of the cross section of the column, fc is the axial compressive strength of the concrete, fyv is the yield strength of the stirrup, Asv is the cross-sectional area of the stirrup, s is the spacing of the stirrups, and N is the axial compression force.
According to the Chinese Code for Design of Masonry Structures (GB 50003-2011), , where is shear strength of the masonry-infilled wall, , and A is the cross-sectional area of the wall.
