gust response factor meaning in English

阵发反应系数

In this paper the author first analysed the wind effects on bridges , and wind - induced vibration is described in particular . second , two methods for wind effects on bridges are discussed , which include the method of gust response factors and the method of buffeting response spectrum . thirdly , from the requirement of practical engineering , the accurate analysis method is simplified according through the parametric analysis , the formula for engineering application of the second method is presented . finally , a realengineering example illustrate the usage of the two methods . and the result of the engineering example show that the stress calculated by buffeting response spectrum method is larger than which calculated from the gust response factor methed , also the temporary method of wind resistant ways for bridge in cantilever state is presented
第二，分析了桥梁抗风分析的两种方法，包括基于阵风系数的阵风分析法和抖振反应谱分析法。第三，从工程实际应用出发，通过参数分析，对精确方法进行适当简化，推导出了桥梁在悬臂施工中的抖振反应谱法的实用计算公式。最后，通过工程实例，采用两种抗风分析方法分别进行了分析计算，实例分析的计算结果说明反应谱法计算得到的内力大于按阵风系数法得到的内力；同时提出了在悬臂施工状态工程施工中的临时抗风措施。
