Research on the Reparability of Structures Based on Post-Earthquake Residual Deformation

Abstract:

The post-earthquake reparability of structures serves a crucial role in modern performance-based seismic design. However, due to intrinsic defects, traditional reinforced concrete structures continuously undergo significant residual deformation during earthquakes. As a result, the repair of these structures can be either technically challenging or economically inefficient. This paper contains a state-of-the-art review of post-earthquake residual deformation. Several technical methods to enhance the reparability of new and existing structures, which incorporate unbonded prestressed tendons or FRP (fiber reinforced polymer) materials, are introduced in this paper.
