例句与用法
1.
Tie beam is an important element in frame - shear wall structure 连梁在框架-剪力墙结构中，也是很重要的一个构件。
2.
The ratio of span - height of an ordinary tie beam is always less 2 . 5 , so the resisting shear is difficult to achieve 由于一般连梁跨高比小于2 . 5 ，使得受剪承载力很难满足。
3.
It also has important reference value for the similar construction . by the safety and seismic evaluation of this aqueduct bridge , it has shown that ( 1 ) besides the structure of this aqueduct bridge was basically unharmed without some flake of concrete cover and revealing stirrup , its intensity basically reached the need of primary design . ( 2 ) from the side of carrying capacity , rib arch could satisfy the needs under the action of wind and earthquake , but some individual frame crossbeams and most rib arch tie beams could n ' t satisfy the need 通过对东滑峪渡槽进行安全性能和抗震性能评估后表明： ( 1 )渡槽除肋拱顶面有保护层剥落、箍筋外露，结构基本完好，其强度基本达到西安理工大学工程硕士专业学位论文原设计的强度要求； （ 2 ）从承载力方面看，在风荷载、地震作用下，肋拱基本满足要求，个别排架横梁不满足要求，肋拱连系梁普遍不满足要求；计入水平横槽向地震作用的工况为设计控制工况。
4.
This paper presents the structural design of the main bridge of lhasa river bridge , makes a deep - going study of the key techniques for design of the bridge , such as the reasonable span length ratio of each span of the 5 - span girder and arch hybrid structure , mechanical behaviour of the dual arch ribs , and section of the continuous girder tie beam , and also works out rigidity and stress conditions of the continuous girder tie beam and stress conditions of the concrete - filled steel tube arches of the main bridge 摘要介绍了拉萨河特大桥主桥结构设计情况，对于五跨梁拱组合桥梁各孔跨合理的跨度比、叠拱的受力行为及连续梁系杆截面形式等设计中的关键性问题进行了深入的研究，给出了主桥连续梁系杆的刚度和应力情况、钢管混凝土拱的应力情况。
