Outline of Final Research Achievements

In Japan, reinforced concrete walls with large opening cannot be treated as structural wall in structural design. Those walls are called “non-structural wall” and its capacity is not generally considered in the structural calculation. In this study, Static loading test was conducted for three reinforced concrete specimens with non-structural wall to evaluate their structural performance. The specimens have structural slits or stress control details for damage reduction of non-structural reinforced concrete walls.
