［提要］西安咸阳国际机场航站区老航站楼项目的改造由于受投资和工期限制，结合业主的要求，在改造设计中确定使用年限30年，抗震设防标准也为30年，为三水准设防。对整体结构作了分析计算，并按三水准设防标准作了补充验算，充分利用了原结构构件的强度。介绍了设计中的一些要点和构造措施，对类似工程有一定的参考价值。

Abstract:Because of investment  and time limit in course of Xi"an Xianyang international airport terminal old buildings rehabilitation and strengthening, the project"s seismic fortification criterion is made on the basis of owner"s demand. Analysis and complementary checking computations are finished according to the three level seismic fortifycaption criterion on the whole structure. The strength of old structural members is used fully. Some conclusion and conformation supply references to similar structural rehabilitation and strengthening.
