| 摘 要： | 轴压比是影响柱抗震性能的一个主要因素,随着轴压比的增大,柱的抗震性能越来越差。从型钢混凝土柱正截面大、小偏心界限破坏时力的平衡条件出发,推导了型钢高强混凝土柱发生延性破坏的轴压力限值,并提出了其在不同抗震等级下轴压比限值,该限值可为型钢高强混凝土柱的抗震设计提供参考依据。

| Abstract: | Axial compression ratio is a main factor affecting the seismic performance of columns.With the increasing of it,the seismic performance of columns becomes poorer.The limit values of axial compression force in ductile damage for steel reinforced high-strength concrete(SRHC) columns is derived based on the balanced condition of forces in the case of balanced failure.Meanwhile,the limit values of axial compression ratio for steel reinforced high-strength concrete columns in various levels of earthquake resistance are presented,which can offer reference for seismic design of SRHC columns. |
