Based on a summary of several existing architectures , we put forward the part crunode degeneration composite architecture 在总结当前几种组织形式基础上提出了部分结点蜕化的混合式组织结构。

There has not been a scientific design theory about the jointless bridge whereas it has been conducted successfully for a long time in the u . s . the actual design ways basically depend on the experience and observaration . what is more , the analytical method and the design of the crunodal details are still dealed with on the whole . in fact , it is a very important part to deal with the crunodal structure between the abutment and beam in the design and conduction of the jointless bridge . in addition , the loaded properties of the crunode are the key and difficulty in the study of the jointless bridge . therefor , there are engineering and practical significances of analyzing the crunodal structure and studying its loaded properties 尽管无伸缩缝桥梁在美国已经成功地使用了很长时间，但至今还没有一个比较科学的设计理论。目前的设计方法基本上依赖于经验与观察，还没有从根本上解决无伸缩缝桥梁有关的分析方法和设计细部构造。应该说，对于无伸缩缝桥梁而言，处理台与主梁的结点构造是设计和施工中非常重要的部分，结点部分的受力性能是研究无伸缩缝桥梁的重点和难点。
