Abstract
The present subject matter relates to systems and methods for providing resistance to soft story collapse in a multi-story structure. Such systems and methods includes providing a multi-story structure having a first floor and one or more upper floors, wherein a structural of the first floor is less than 70% of a structural stiffness of the one or more upper floors, and decreasing the structural stiffness of the one or more upper floors to be less than or substantially equal to the structural stiffness of the first floor.
Claims6
A method for providing resistance to soft story collapse in a multi-story structure, the method comprising:
- providing a multi-story structure having a first floor and one or more upper floors, wherein a structural stiffness of the first floor is less than 70% of a structural stiffness of the one or more upper floors;
- and
- decreasing the structural stiffness of the one or more upper floors to be less than or substantially equal to the structural stiffness of the first floor, wherein the one or more upper floors comprise a structural frame and one or more infill walls, and wherein decreasing the structural stiffness of the one or more upper floors comprises modifying the structural frame and the one or more infill wall of the one or more upper floors to have no in-plane interaction.
A method for providing resistance to soft story collapse in a multi-story structure, the method comprising:
- providing a multi-story structure having a first floor and one or more upper floors, wherein a structural stiffness of the first floor is less than 70% of a structural stiffness of the one or more upper floors;
- and
- decreasing the structural stiffness of the one or more upper floors to be less than or substantially equal to the structural stiffness of the first floor, wherein the one or more upper floors comprise a structural frame and one or more infill walls, and wherein the structural frame is substantially decoupled from the one or more infill wall of the one or more upper floors such that in-plane interaction is reduced.
