简要介绍了静力弹塑性分析(Pushover)能力谱方法的原理,并就桥墩刚度分布情况,对静力弹塑性分析结果产生的影响进行了研究。在六种不同的桥墩刚度分布情况下,建立桥梁模型进行了分析。分析结果表明,不同的桥墩刚度分布情况对静力弹塑性分析结果存在较大影响。
The principle of Pushover capacity spectrum method is briefly introduced. The influence of static elasto-plastic analysis results on the distribution of pier stiffness is also studied. Under the condition of six different stiffness distribution of bridge piers, the bridge model was established. The analysis results show that the stiffness distribution of different piers has great influence on the results of static elasto-plastic analysis.
