Effects of Pretension Design Value on Anti-sliding Coefficient Test

After the sliding load has been tested by using different pretension value on anti-sliding coefficient test, the anti-sliding coefficient can be calculated. By tensile test of high strength bolt, the actual tensile strength will be tested. Then the pretension value will be calculated. It can be solved about the problems of using different standard values. To a certain extent, the best bolt material performance could be excavated and the anti sliding coefficient test pass rate would be improved.
