Gravity Load Collapse of Reinforced Concrete Columns with Brittle Failure Modes

During the 1995 Kobe earthquake, dozens of concrete buildings suffered complete collapse at an intermediate story. Such collapse is believed to have occurred due to the gravity load collapse following shear failure of Steel Reinforced Concrete (SRC) or Reinforced Concrete (RC) columns at a certain intermediate story. To study this collapse tests of RC column specimens were conducted. Test parameters were axial load and loading history. The tests have revealed that: 1) collapse occurs when shear force decreases to about zero, 2) axial load level is decisive for the collapse behavior, 3) loading history occasionally has a significant effect on the collapse behavior including a failure mode, and 4) a change in vertical deformation increment vs. lateral drift increment relations until collapse can be explained by the flow rule in plastic theory considering reduced failure surface.
