Abstract:The relationship between local deformation mechanism and the whole
   deformation mechanism of shear walls is one of the key points to
   establish theoretical structural model of shear wall based on the FAM
   (force analogy method) method. FAM is an inelastic analysis method based
   on changing the structural displacement field instead of changing
   structural stiffness in the traditional method. In this way, it can save
   storage space of stiffness, improve the solving efficiency and
   stability, and offer an excellent way for the nonlinear dynamic analysis
   of structures. Firstly, the fundamental theory of FAM was introduced and
   the core thinking for the establishment of mechanical model based on FAM
   was discussed. Then, the development process of two kinds of method used
   for shear wall analysis, as well as the failure modes, the failure
   mechanism and the determing method of skeleton curve of the shear walls
   were reviewed and summarized. Finally, reasonable suggestions and
   prospects are put forward for the exploration of mechanical model of
   shear walls based on force analogy method, which will be a new
   development for shear wall analysis and a supplement of the FAM theory.
