发布时间:2016-1-23 16:05:22 浏览次数:743

1.于化学物质的侵蚀而产生腐蚀以及电化学腐蚀致使钢结构构件截面削弱。


2.荷载变化,超期服役,规范和规程改变导致结构承载力不足。


3.差作用下引起构件或连接变形、开裂和翘曲 。


4.构件由于各种意外产生变形、扭曲、伤残 、凹陷等,致使构件截面削弱,杆件翘曲,连接开裂等。


5.包括设计、生产、 施工中的失误及服役期中的违规使用和操作等。


针对钢结构上述因素造成的钢结构损坏,可采取截面补强法、改变计算简图、预应力拉索法钢结构加固技术措施的这三种方法即可修已损坏的钢结构。



1 Corrosion and electrochemical corrosion resulting from the erosion of the chemical substances resulting in the weakening of the section of the steel structure.
2 load change, extended service, rules and regulations to change the structure of bearing capacity.
3 difference caused by the component or connection deformation, cracking and warping.
4 members due to various unexpected deformation, distortion, disability, depression, etc., resulting in the weakening of the member section, the rod warping, connection, cracking, etc..
5, including the design, production, construction and operation of the mistakes in the use and operation of the service and so on.
In the steel structure for the steel structure of the above factors caused the damage, can take the cross section reinforcement method, changing the calculation diagram, the method of prestressed cables steel structure reinforcement technology measures of these three methods can repair the damaged steel structure.
