It is very inconvenient when the discontinuous Coulomb friction model is used to simulate the friction force-velocity relationship in numerical analysis, so the continuous viscous yield model is proposed to solve the problem. After the reduction of the degree of freedom and the proper transformation, the dynamic analysis of a braced frame with friction dampers sum up to solve a differential-algebraic equations of index 1. An increment type Rosenbrock semi-implicit Runge-Kutta method of order 3 with stage number 2 is adopted to solve those equations in order to consider the material and geometry nonlinearity of the frame and braces. The elasto-plastic dynamic response of a five-storey braced frame with friction dampers is presented as an example for the practical application of the proposed numerical technique . The effects of some parameters, which are the stiffness ratio of bracing and corresponding structural story, initial slip force and seismic wave type, are also studied.
