摘要：

An all-steel bamboo-shaped energy dissipater (SBED) composed of a bamboo-shaped core and a buckling-restrained tube was recently proposed. However, systematic parametric studies on the effect of experimental parameters of SBED have not yet formed, as well as design method. In this paper, the numerical model established for SBED was firstly calibrated based on previous test results. Then, five series of numerical cases were conducted to evaluate the effects of different geometrical parameters on the performance of SBED. Besides, a design method of SBED was further provided in terms of certain demands of bearing capacity and deformation of SBED.
