摘要
讨论了结构拟动力试验中常遇到的一些问题,包括缩尺模型相似关系设计、试验阻尼比的确定、附加质量和竖向荷载施加方法、初始条件处理、试验输入地震波和加载工况的选取等,给出了一些对结构拟动力试验具有参考应用价值的结论和建议。
Some problems in pseudodynamic tests, damping ratio, additional mass and vertical loading which included similitude rules for test model design, method, initialized parameter of test, input earthquake waves and loading programs, were discussed in this paper. As the conclusion, some suggestions which can be used as references for pseudodynamic tests were presented.
