Ultimately, the shear mechanism analysis model of SRC special-shaped joints was proposed, and the shear capacity calculation formulas of SRC special-shaped interior joints, variable-column exterior joints and leaning beam-column exterior joints were established. According to the above analysis results, the shearing capacity of different types of special-shaped joints was mainly composed of webs, stirrups and concrete inclined-compression-struts, namely: (30) V j V aw + V sv + V c where V aw is the shear capacity of webs. Keywords : dead rise, limit strength, longitudinal stability. Back calculation from measured deformation shows the conservative estimation of stiffness. Strength and stiffness calculations of bottom grillages with dead rises and selection of dock struts for transverse bulkheads. A clear benefit of using struts is that there are no tieback openings in the slurry wall, thus eliminating one source of leakage. This is larger than the typical spacing when tiebacks are used, because the pre-loading levels are much higher.

The results indicate that the shear capacity of the joints was mainly borne by webs, stirrups and concrete inclined-compression-struts. by Plaxis 2D is 2 92.77KN/m where as wallap software calculate d 784.90. The typical strut spacing is in the range of 15ft, both in the vertical and the horizontal direction. Furthermore, based on the experimental study, the finite element analysis (FEA) method was used to verify the experiment, and 14 finite element models (FEMs) were established for parameter analysis. The effects of axial compression ratio, dislocation height of the beam, the sectional height difference of beams, the sectional height difference of columns, the inclination angle of leaning beams and other factors on the shear bearing capacity of joints were studied. The failure modes of different types of SRC special-shaped joints, and the shear mechanism and capacity of the joint were analyzed. In this paper, 15 specimens of steel reinforced concrete (SRC) joints were tested under horizontal cyclic loading.
