| Abstract: | When analysing the earthquake responses for structures regarded as discrete multidegree-of-freedom systems, the part effects caused by distributed masses are usually neglected. This paper comes up with a simple and reasonable proce- dure based on reference. Through some examples analysing the earthquake res- ponses, it can be seen that the part effects can not be neglected. |
