For the design difficulties of high intensity region school buildings, such as beam section dimensions are too large, super reinforced serious, etc. In this paper the combination scheme using buckling restrained brace and shear mild steel damper was proposed.Through the analysis of actual project cases, compared with the traditional scheme and energy dissipation schemes, the results show that the energy dissipation scheme does not affect the architectural features, greatly improving seismic performance of structures, and more cost savings.Keywords: Seismical energy-dissipated design, energy dissipation device, buckling-restrained brace, shear mild steel damper, elasto-plastic analysis
