Mechanical Behavior Analysis of Frame-Rocking Wall Structures After Being Damaged
In this paper,the mechanical behavior of frame-rocking wall structures(FRWSs)after being damaged has been investigated based on the discrete-continuum parametric model.It's assumed the damage only occurs in the RC frame,and the mode of'strong column and weak beam'is not realized.The damage appears in the way of plastic hinges at the column ends.The research results demonstrate that compared with the undamaged FRWS,all the maximum lateral deformations after being damaged increase,but the change of maximum internal forces has no clear law.The variation of both are related to the locations of the floors where the plastic hinges generate and the form of the plastic hinges.Finally,a conclusion can be drawn that it's beneficial to reduce the internal forces and make the inter-story drifts uniform if a weak story is set intentionally for a FRWS.
