- Abstract
A new tie column such as core column, named as core tie column, for the substitution of cast in place tie column was used to improve seismic performance of mansonry structures. Pseudo static testes of 11 wall specimens including 6 walls constrained by core tie columns, 2 walls constrained by cast in place tie columns, and 3 walls without constraints were carried out to study the seismic deformation capacity of mansonry walls with core tie columns. The skeleton load displacement curves and the normalized skeleton curves, displacement ductility factors，drift angels of the specimens were analyzed and compared. The effects of the level of vertical compress load, aspect ratio and the wall style on the deformation capacity of the wall with core tie columns were distinguished. It is shown that the constraints effects of core tie columns on masonry wall are effective and the walls with core tie columns have good deformation capacity as those with cast in place tie columns.
