门式刚架简化模型的随机振动分析与应用

Analysis and Application of Random Vibration of the Simplified Steel Structure With Gable Frame Model

通过门式刚架的简化模型开发一简单的随机振动计算程序,用于门式刚架随机振动的估算,便于在设计时对门式刚架的随机振动进行简单的评估。并以一典型的门式刚架为例,通过ANSYS软件进行模拟计算,比较结果,验证分析的正确性。对于工程实际中结构的随机振动分析具有一定的实践和参考价值。

With the simplified steel structure with gable frame model,the article developed a simple random vibration calculation program.It can be used in assessment the random vibration analysis of steel structure with gable frame.Taking a typical steel structure as an example,the paper made a comparison of the calculating results with that of ANSYS software analysis in random vibration.It is believed that the analysis in random vibration has some reference value.
