摘　　要：南京站主站房下部为混凝土结构,屋盖为斜拉钢结构。由于建筑造型的需要,结构复杂。对这种混合结构进行地震模拟振动台试验时,如何保证原结构与模型间的相似性是一个很重要的问题。本文较详细地介绍了此次地震模拟振动台试验的过程,包括模型材料的选择、模型的制作、地震波的选择、振动试验、结果分析等方面的内容,可为类似结构进行振动台试验提供参考。模型试验结果表明,在振动台模型中分别用砂浆和铜材模拟混凝土和钢材是完全可行的;对于屋盖为钢结构,下部为钢筋混凝土结构的混合结构,在地震作用下,下部钢筋混凝土更为不利;对于类似单向受力特性明显的结构,加强纵向联系是十分必要的。In Nanjing Railway Station, concrete is used as the main structure and stay-cable steel structure as the roof construction. The special architectural form leads to a complicated structure. In shaking table test of such composite structure, an important problem is how to ensure the similarity between the prototype and model. In this paper, the test process is presented in detail, including selection of model material, model making, choice of earthquake wave, vibration test and results analysis, which may be useful for shaking table test design and giving reference to test of similar structures. The test results indicated that mortar and copper can work well in the test model in places of concrete and steel in the actual structure respectively. As for the composite structure with steel as roof and RC as infrastructure, it is more unfavourable to the latter when subjected to earthquake action. Besides, it has the necessity to strengthen the longitudinal rigidity of the structures which has the outstanding features of one way load-carrying characteristic.
