| 摘 要： | 对钢筋混凝土框架结构安定性分析的必要性及原理进行了初步论述，推导出计算公式并编制了计算程序，通过实例分析获得了结构的安定域。结果表明当反复荷载为对称循环变化时结构所能承受的最大荷载值与静力极限荷载值差别最大，而非对称循环时差别较小。

| Abstract: | The necessity and principle of shakedown analysis of reinforced concrete frame structure are discussed in this paper, the formulas are derived and a program is drawn up to analyse the frame under the action of alternating loads. Through the numerical example analysis the shakedown domain of structure is 'obtained. The calculation results show that the difference between the maximum value of alternating loads which can be carried by structure and the value of static limit load is largest for symmetric cyclic loading, and it is smaller for unsymmetric cyclic loading. |
