Experimental Study on Impact Response of Rc Beams Falling on to Level Keeping Device

Key Points

• To collect fundamental data on the shock behavior of RC beams when falling on a level keeping device.
• Conducted experiments by freely dropping RC beams onto a cushioning rubber simulating a level keeping structure.
• Varied the thickness of the cushioning rubber and the height of the drop to assess their impacts on shock absorption.
• Supported one end of the RC beam with a pin and the other end on a steel base or cushioning rubber.
• Installation of cushioning rubber reduces maximum impact force by over 50% regardless of drop height.
• The reduction in impact force increases significantly with thicker rubber cushions.
• The deformation behavior of the beams remains similar overall, regardless of using cushioning rubber, except near the point of impact.
