Objective: To study the connection behavior of the vertical joint and the effect of shear span ratio on the mechanical behavior of the new-typed prefabricated shear walls with the vertical joint, quasi-static tests for three walls have been carried out. Results and Conclusion: The results show that the shear span ratio has significant effect on the mechanical behavior of the new-typed prefabricated shear walls, and the new-typed prefabricated shear walls have good ductility, all the ductility factors are greater than 4.0. The study also proves that the construction of the vertical joint is reasonable and its connection property is reliable. The vertical joint which can ensure the effective connection between different assembly units on horizontal direction can be used to guide the practical engineering.

Introduction: The hollow slab shear wall structure is a new type of shear wall structure by industrial production. Objective: To study the mechanical performance of the new-typed walls with different horizontal bars strength, quasi-static tests were carried out for two hollow slab shear walls. Result and Conclusion: The results show that strength of horizontal bars has a little influence on the hysteretic behavior and the deformation ability. While the decrease of the strength of horizontal bars can increase the yield displacement and the peak displacement of the hollow slab shear walls. The hollow slab shear wall structure has good deformation capacity, and the brittle shear failure can be avoided.
