摘要
以足尺钢筋沥青隔震墩砌体房屋的正弦激励振动台试验为基础,利用分析软件ANSYS建立空间有限元模型,对钢筋沥青隔震墩进行了数值模拟。并将数值模拟的结果与足尺砌体房屋的正弦激励振动台试验结果进行了比较。结果表明:有限元分析结果与试验结果基本一致,进一步验证了钢筋沥青隔震墩的有效性和软件ANSYS用于结构隔震分析的可信性。并得出相关结论:钢筋沥青隔震墩砌体房屋在基底激励作用下隔震效果良好,钢筋沥青隔震墩技术是一种适用于砌体结构的隔震技术。
Based on the sinusoidal excitation shaking table test of full-scale reinforced asphalt isolation pier masonry building,the ANSYS is applied to set the spacial finite element model,and then the numerical simulation is given to the isolation pier. Comparisons of the results of numerical simulation and shaking table test indicate that they agreed well with each other. The result demonstrates the effectiveness of reinforced asphalt isolation pier and the credibility of ANSYS used to isolation analysis. Reinforced asphalt isolation pier masonry building presents the excellent isolation performance under base excitation,and the higher the frequency of loading pressure,the better the performance is. The reinforced asphalt isolation pier technology is suitable for masonry structures.
