| Abstract: | A long-span grid structure was detected and an appraisal of reliability is drawn.It was found out some problems of security in this grid structure,such as those of bolt balls,members,supports and so forth.Based upon results obtained in inspection,a finite element model was set up to analyze and calculate the bearing capacity of this structure.A grade evaluation for the stability of this grid structure was presented and some proposals for domestic grid structure detection are offered. |
