Experimental Study On Aseismic Property Of R.c. Shear Wall With Concealed Bracing And Different Height-width-ratio

In this thesis, the experimental study is carried out on the aseismic behavior of R.C. shear wall with rims and concealed bracing, in particular, 4 models of higher height-width-ratio and 6 models of lower height-width-ratio. Based on the cyclic loading experiment of 10 R.C. shear wall modes of different height-width-ratio, fonnation of slits and concealed bracing, such characteristics of the structure are analyzed: capacity, stiffness, ductility, hysteresity capacity, energy dissipation and failure phenomena. In addition, the aseismic property of R.C. shear wall with the same height-wide-ratio and different aseismic measures is compared. Furthermore, based on theoretical analysis of experiment, the mode formulas of restoring forces, capacity and stiffness are established, which have been proved good effectiveness by experimental results. It shown that compared to ordinary R.C. shear wall with rims, the capacity, ductility and energy dissipation of R.C. shear wall with rims and concealed bracing in high or low height-width-ratio have been improved, and that this kind of R.C. shear walls have good aseismic property.
