Three-dimensional submodel for modelling of joints in precast concrete structures
The shear capacity of in-situ cast joints is crucial to the overall stability of precast concrete structures. The current design is based on empirical formulas, which account for neither the reinforcement layout of the joint nor the three-dimensional stress states present within the joint. In this paper, a semi-analytical submodel is presented. The model is formulated as an optimisation problem within the framework of numerical limit analysis. The presented submodel is capable of describing the key mechanisms within the joint and the model is verified by comparison to existing numerical models. The shear capacity of the joint subjected to triaxial stress states is analysed and the results are discussed.
