- Abstract
In order to investigate the influence of concrete strength,horlzontal and verticalportions of anchorage length and cover thickness etc,upon the mechanical performance of 90-degreehooks of beam upper bars in exterior joints,static experiments of 40 beam- column subassemblagesare carried out. This study emphasizes the damage characteristics of the anchorage zone,measures thestrains of the bars along the anchorage length and analyzes the special anchorage mechanism of suchhooks of beam bars.
