AN EXPERIMENTAL STUDY ON ANCHORAGE OF TENSILEREINFORCEMENT OF WALL-COLUMNS AT THE TOP STORYOF RC WALL-FRAME STRUCTURES WITH FLAT-BEAMS

摘要

It is a distinctive feature of a reinforced concrete wall-frame structure with flat-beams that wall-columnsare connected to wide and thin beams, i.e. flat-beams. Because of this feature, it is difficult to ensure theanchorage length of tensile reinforcing bars of wall-columns at the top story. New details of anchorage forthe tensile reinforcing bars were proposed to solve the problem, and seismic loading tests on jointspecimens of a wall-column and flat- beams were carried out to verify the effectiveness.
