New Concept of Structural Seismic Design:Earthquake Resilient Structures

Abstract:

Earthquake resilient structure is a new branch of the seismic structural design.The new structural system is not only capable of preventing from the structure failure so as to protect people’s life safety during an earthquake,but also restoring immediately the structural function after an earthquake.A research was made of several kinds of resilient structures such as replaceable structure,rocking wall,rocking frame and selfcentering structure.The paper presents a summary of the recent research on different kinds of resilient structures,and also a new replaceable technology for coupled shear wall,replaceable coupling beam and replaceable shear wall toe.

Key words:earthquake resilient structure; replaceable member; rocking wall; rocking frame; selfcentering structure
