摘要
计算结构物的自振周期的经验公式一般是通过实测同类结构物的自振周期后用统计回归的方法得出的 ,但传统的方法一般都比较复杂。基于累积方法提出一种确定计算结构自振周期经验公式的新方法 ,该方法可以充分的反映结构自由振动的实际状况 ,得出更准确的结构自振周期的预测值。该方法简单、实用 ,有广阔的应用前景。
The building structure natural period experimental formula is educed by regressive method based on the measure data of the true similar building structure natural period, the conventional regressive method is complicated. Based on cumulate method, a new determinate method of the building structure natural period experimential formula is established. The main advantages of this method are full represent practicality conditions of the building structure free vibration, it can make reasonable prediction of the building structure natural period. The results of some examples are show that the building structure natural period experimential formula obtained from this method has higher accuracy. This method is the simple and practice, and can be applied in certain cases.
