- Synopsis
- Reported is a fundamental study on a development of the newly devised concrete
guard fence that is a separated type structure having the upper and lower
walls with a buffer part. Static loading test and 3D FEM-nonlinear analysis
for both the separated and usual non-separated wall type guard fences of unit
width (1 m) are performed, and then the results obtained are compared to show
mainly the following three mechanical feature of both types of guard fence
:
1. Mechanical behavior of both types of guard fence.
2. Difference of mechanical characteristics due to the use of single and double vertical reinforcements, which connect the upper and lower walls of separated type guard fence.
3. Efficiency of the use of rubber as a shock absorber in buffer part of separated type guard fence. - Keywords:
- concrete guard fence, separated type structure of upper and lower walls, buffer part, experiment of static loading, 3D FEM analysis
