This paper discusses how to increase the blast resistance of beams effectively by elastic and damping supports at the ends of beams.

Rigid supports like clamped and simple supports are not actually adopted at the ends of arches in the engineering,but flexible supports such as elastic supports,damping supports are adopted.

In the condition of accidental water-losing from ship-chamber of TGP s ship-lift, the stability againstlongitudinal inclination of ship-chamber, champing loads and the variation of lifting tensile forces in steel cablesunder the clamping state, suspension state and sirnulated guide-bearing resistance state respectively were studiedon the TGP s vertical comprehensive model with a 1:25 scale.
