| Abstract: | This paper studies the friction coefficients between nuts with different surface treatments and single-sided steel plates in steel plate composite walls constrained by high-strength tension bolts.Through the experiments,5 friction test pieces for flat nuts and 5 friction tests for nuts with anti-recessing grains were made respectively.Then the friction coefficient of the friction surface is obtained by the tensile tests,which is,0.152 between the flat nut and the steel plate and 0.163 between the nut with anti-recession and the flat steel plate.Furthermore,a model under the same working conditions as the experiments was established,and the results of the numerical simulation were consistent with the experimental results.It shows that the experimental data is relatively accurate and could provide reference for the similar projects. |
