曲底
Examples
- Curved bottom chord
曲线形下弦杆 - The research information of the slab that has been used for forepassed decades is extremely few . there is a lack of the method of calculating load bearing capacity of slab with slightly curved bottom in our bridge criterion
在过去的几十年中，微弯板的研究资料极少，我国桥梁规范中尚无微弯板的承载力的确定方法。 - Because it is simple to make manufacture slab with slightly curved bottom , and is economical to use steel , and is relatively great in aspect of load bearing potential capacity , the slab often has been used as braced arch and rigid - frame arch bridges " deck slab in 1970s and 1980s
由于微弯板具有制作简单、用钢量省、承载潜力较大的优点，因而上世纪七、八十年代，在刚架拱桥、桁架拱桥中常用作桥面板。 - On the basis of the test and finite element analysis , and on the experience of exsting research payoffs , this paper advance the method of calculating load bearing capacity of slab with slightly curved bottom considering membrane effect of the slab , and deduce the corresponding formulas
在试验和有限元分析的基础上，借鉴已有的研究成果，本文提出了考虑薄膜效应时确定微弯板承载力的方法，并推导出相应承载力计算公式。 - The mass of the slab have diseases in varying degrees by investigation , so the problem faced us is to strengthen and remake the slab . in addition , the slab will be used in underdeveloped region of our country . therefore , it is very important to evaluate the load bearing capacity of slab with slightly curved bottom
微弯板在桥梁中使用已有三十多年，在调查中发现大多微弯板都存有不同程度的病害，也就面临着对旧桥微弯板的加固改造的问题；另外，在我国某些经济尚不发达地区的桥梁建设中仍在采用，因此，对微弯板的承载力的正确评定也显得十分重要。
