Abstract

A new structural wall system has been proposed to enhance the seismic performance of reinforced concrete walls. The new wall system is slotted vertically along the central axis unlike the conventional reinforce concrete wall. Metallic plates, featuring a series of parallel diamond-shaped holes, are strategically employed to connect the two inner sides of the slit wall. To further enhance ductility and energy dissipation capacity, a yielding scheme has been specifically designed for the metallic plates. The configuration and design methodology of the slit wall are established accordinA new structural wall system has been proposed to enhance the seismic performance of reinforced concrete walls.

Metallic plates, featuring a series of parallel diamond-shaped holes, are strategically employed to connect the two inner sides of the slit wall. To further enhance ductility and energy dissipation capacity, a yielding scheme has been specifically designed for the metallic plates. The configuration and design methodology of the slit wall are established according to its lateral deformation. Finally, numerical simulations are conducted to validate the design method of the metallic damper and the slit wall. The analysis results have shown that the new structural wall system can achieve a desirable performance of energy dissipation.g to its lateral deformation.
