桥梁用附加装置的发展和创新

超大跨径桥梁或强风、强震区的大跨径桥梁，其的静力、动力响应对桥梁结构设计往往成为控制因素，运用缓冲器、阻尼器和弹性连接等附加装置能有效地改善大跨径桥梁结构受力。在苏通大桥结构体系研究的一些思路和国内外有关资料的基础上，将十多年来应用的一些装置从性能、特征参数和工程应用理念等方面加以较系统地叙述，希望为我国桥梁在这方面的应用提供一些有益的帮助。

Development and Innovation of Attachment Device on Bridge

The structural response to static and dynamic loads often becomes the controlling factors to ultra-span bridges and long-span bridges in the strong wind and earthquake areas.The application of attachment devices of buffers,dampers and elastic connections can effectively improve the mechanic behavior of long-span bridges.Considering domestic and abroad research and the structure system research of Su-Tong Bridge systematically elaborates the attachment application on aspects of structure performances,charac- teristic parameters and application ideas,which provide reference for the similar projects.
