Outline of Final Research Achievements

In seismic design of walls in reinforced concrete buildings, one should consider the effect of vertical openings such as doors. Many damages were observed above door openings after severe earthquakes. In this research, three types of specimens were constructed: a wall without opening, a wall with openings aligned vertically, and a wall with openings aligned diagonally. The wall with openings aligned vertically showed significantly smaller strength than that predicted by the current design code.
