| Abstract: | To overcome some problems in seismically retrofitting of buildings, the authors use VFD as an effective device for hybrid masonry-concrete structures to meet the requirement of current earthquake-resistant codes of China. Based upon the fractional derivative model of viscoelastic damper and force-deformation-slip relation of friction element, a precise finite element model of VFD is constructed, and the method of forming element stiffness matrix and control force vector of VFD is deduced in this paper. Consequently, a time history analysis method for earthquake-excited damped hybrid masonry-concrete structures is developed. |
