屋面空间网架结构使用性能检验方法的研究与应用

Research and Application on the Testing Method of Service Performance for Roof Space Grid

使用性能检验是检验结构或构件实际受力状况及工程质量的有效手段,但鉴于网架结构自身具有的特点,对其进行使用性能检验存在较大的难度。因此,现有的文献资料对其研究相对较少,也缺乏系统性。在已有研究的基础上,本文对屋面网架结构使用性能检验方法进行了较为系统、详细地研究,并通过实际工程加以验证和补充。实践证明,对屋面网架结构使用性能检验的方法具有较强的操作性。

Service performance testing is an effective means in examining actual stress status and quality of structures or components.However,developing the service performance testing in space grid has certain difficulty because of its own characteristics,so the literature data is relatively less and not systematic at present.Based on the data available,the service performance testing methods of space grid are studied in fairly systematical and comprehensive way,which are verified and supplemented by practical engineering,in this paper.It has been proved by some engineering that the methods are feasible and practical in the service performance testing for roof space grid.
