提出了一种新方法用来进行单层工业厂房排架结构地震反应计算，这种方法能够精确地计划数值化地震波作用下单层工业厂房结构的动力反应。新方法是利用分段插值多项式逼近任意动力荷载，当动力荷载也为分段多项式时，Duhamel积分是有精确解的，因而和传统逐步积分法相比，新法不但具有较高的计算精度，而且大大减少了计算工作量。

In this paper, a new method for computing seismi c response of a bent frame structure for single-story industrial building is pr oposed. This method can accurately calculate seismic response of the structure s ubjected to numerical earthquake wave. We approximate arbitrary dynamic load ter m in the Duhamel integral by piecewise interpolation polynomial. Because the Duh amel integral of piecewise polynomial is precise, the proposed solution techniqu e has the higher accuracy and much less calculations than traditional step-by- step integration solution.
