And the point is presented that the multi-storey building in high intensity area has equivalent shear-weight ratio. Then from the point of satisfying the architectural function requirement, main computation indexes, and economic indexes, three design schemes are compared and the new design way for frame structures that the global design is carried out according to the safety evaluation report, and the frame column is designed according to the parameters provided in codes. The static elastic-plastic analysis show that the frame structure designed according to the way in this paper has good seismic performance. Keywords: high intensity; multi-building structure; equivalent shear-weight ratio; static elastic-plastic analysis; strong column and weak beam 0 引言 区时，框架柱及框架梁截面尺寸的确定主要取决于层 高烈度地区（抗震设防烈度 8 度以上）由于地震 间位移控制的要求，以及高烈度区用框剪结构方案替 作用很大，使得即便是结构总高度在 20m 以下的多层
