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

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.
