Reducing Effect of Vibration on Footing using Different Materials
Keywords:
Trench, Materials, Isolated, VibrationAbstract
This paper investigates the reduction of vibration effect between two footings by placing a trench between them. On the first footing (designated as the source footing), on electric-rotary motor is fitted, it has dimensions of (80x80) mm. Beside the source footing a second footing is placed and on this footing the reduction in vibration effects are to be investigated. Both the source footing, nearby footing and trench are placed over compacted gypseous soil in a steel tank having gypsum content with (50%). Tests are performed under dry and soaking conditions. The tests are managed under dynamic load for three frequencies (8,14 and 20) Hz, to install amplitude, velocity, and acceleration of the footing before and after drilling the trench, also to compare between the materials to choose the best material to reduce vibrations. The results showed that all parameters in above for the footing varying in values when change the material used to filling trench.
