The thesis verifies the availability of ductility detailings of elements prescribed by code through comparing the actual rotation capability of both ends of columns and beams obtained from inelastic dynamic analysis and the maximal rotation capability which columns and beams can possess through adopting the detailings in the code 本文通过对分析所得的梁、柱端实际塑性转动和采用规范构造措施后的构件可能具有的转动能力进行对比检验了规范构件延性构造措施的有效程度；并再次确认了柱截面尺寸沿高度收小(变截面)以及当顶部楼层柱轴压比小于0
