| Popis: |
With heavy hammer hammering method and road roller vibrating fixed-point method, field tests on dynamic characteristics were conducted for the brick-concrete structure beam of a teaching building. The experiment results of heavy hammer hammering method show that the horizontal and vertical natural frequencies of the heavy hammer are respectively concentrated in 2.726 ~ 5.313 Hz and 3.596 ~ 9.104 Hz, horizontal and vertical peak acceleration values are respectively 489.56 ~ 532.05 m/s 2 and 248.77 ~ 494.61 m/s 2 |
