This study focuses on the push-out tests performed for verifying the performance of Y-type perfobond rib shear connectors. The end bearing resistance of the Y-type perfobond rib shear connector may be determined by the sizes of rib height and rib width. Therefore, in this study, the end bearing resistance is analyzed according to the rib widths and rib heights.

This study conducted seismic performance evaluation of externally reinforced water tank using shaking table test. From the shaking table test result, externally reinforced system shows sufficient stiffness for water tanks and high natural frequency over 8Hz. The test result also showed safety result of induced maximum stress of water tank shown in the allowable stress.
