- Synopsis:
- This research has an intention to reveal shear destruction behavior of PC beams which are given impact load through sand or gravel cushion to a near point of a support. The first step of the experiment is weight falling test onto a buffer sand box placed on a PC beam, and then the residual bearing capacity of damaged beams are statically measured. With these experiments, buffer effect of sand or gravel on shear destruction of PC beams is quantitatively understood to some degree.
