u-beam 中文意思是什麼
u-beam
解釋
槽形梁-
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
盡管無伸縮縫橋梁在美國已經成功地使用了很長時間，但至今還沒有一個比較科學的設計理論。目前的設計方法基本上依賴于經驗與觀察，還沒有從根本上解決無伸縮縫橋梁有關的分析方法和設計細部構造。應該說，對于無伸縮縫橋梁而言，處理臺與主梁的結點構造是設計和施工中非常重要的部分，結點部分的受力性能是研究無伸縮縫橋梁的重點和難點。 -
