【 摘 要 】

The influence of the setting of the scissors support on the ultimate bearing capacity of the high-formwork support system is analysed in detail by the finite element software Midas Gen. The results show that with the gradual increase of the erection density of the horizontal scissors support, the waveform of the unstable buckling mode gradually becomes slower, and the corresponding wavelength reduced, however, the horizontal scissors support imposes limited effect on increasing the bearing capacity of the high-formwork support system while the setting of the vertical scissors support is rather crucial. The ultimate bearing capacity can be lifted about 2.3 times by reasonable setting of the vertical scissors support than that by the horizontal scissors.
