| 摘 要： | 分析了某钢结构异形塔架在不同荷载作用下的静力和动力性能，以及塔架在各方向风荷载作用下的性能．分析了塔架刚度的影响因素，包括考虑不同横膈布置对刚度的影响及不同连接方式对塔架结构刚度产生的变化．研究表明，风荷载是该塔架设计的控制因素，地震作用和温度应力对其影响不大．

| Abstract: | The behavior of an abnormity steel tower against different loads and dynamic characteristics are investigated. The analysis show that it is not the permanent loads, earthquake action and change of temperature but the wind loads is the key fact. Meanwhile, the factors affecting structural rigidity such as arrangement of diaphragm steel and connections are also taken into account. |
