Numerical Simulation Methodology for Prefabricated Shear Walls Considering Stochastic Defects in Grouting Materials

The most used connection form for reinforced steel bars is the grouting sleeve using cement-based materials. Hence, quality of determines whether performance a precast concrete structure equivalent to that cast in situ structure. However, several existing reasons, namely, insufficient cement or poor construction controls and even stochastic bubble holes, lead inevitable defects. behavior structures affected dramatically. Considering cost efficiency analysis structures, finite element method still method, but simulation technology considering defects materials not sufficient. Herein, proposed, application sleeves shear wall performed verify its accuracy feasibility. material first realized through Python scripter. Secondly, mechanical parameters are obtained from refined with Finally, based on properties sleeves, behaviors walls under blast loading analyzed. simulations uniaxial tensile both indicate proposed numerical feasible solving structural issues
