Bearing capacity reduction factor of high strength bolts in the application of steel grid structures

WANG Yong1,SONG Yan2,ZHANG Shuxun1(1.National Centre for Products Quality Supervision and Inspection of Network,Xuzhou 221006,China; 2.Xuzhou Institute of Technology,Xuzhou 221008,China)  
High strength bolts as the important tension member,having crucial effect for bearing capacity of grid structure.Especially for in-service engineering,when high strength bolt tensile load doesn't meet the standard requirements,how to determine the structure bearing capacity influence is particularly important.The article is aimed at the situation of the design review and analysis,through the bearing capacity reduction,reducing the high strength bolt bearing capacity,and the reduction of bearing capacity and the actual force are compared,to determine the safety of the structure.Through the question processing,provides a discussion for solving the similar problems.
