摘　　要：大跨预应力井式梁框架结构是由现代预应力技术和井式梁框架结构结合而成的一种新型结构体系,它可满足现代建筑的大空间使用功能要求。利用模拟地震振动台对这种大跨预应力井式梁框架结构的抗震性能进行了研究。模型结构动力特性与加速度和位移反应试验结果表明,大跨预应力井式梁框架结构具有良好的整体刚度和抗震性能。Large-span prestressed concrete grillage girder frame st ructures have proved to be the effective application of the prestressing technol ogy to the grillage girder frame structure.They are capable of meeting the needs of large space for mordern architectures. It is well known that it is of vital importance to carry out an appropriate earthquake-resistant design for this sor t of structures. The shaking table test has thus been conducted of a large-span prestressed concrete grillage girder frame structure to gain an insight into it s earthquake-resistant performance. In terms of the dynamic characteristics, ac celeration and displacement responses of the model structure,large-span prestre ssed concrete grillage girder frame structures possess remarkably good integrity and favourable earthquake-resistant performance.
