38. Experimental stand “Dynamic and vibration monitoring system of substructure-foundation scheme”
The stand is designed for developing of methods which are used to detect and control potentially hazardous alterations in substructure-foundation scheme. The stand operates with procedure of registration and analysis of dynamical characteristics.
The stand contents:
- rigid support frame
- support system
- lift system
- physical model of a base slab
- monitoring system of a testing model characteristics and support system parameters
- system of collecting and analysis of characteristics of monitoring subsystems
- system of mathematic simulation and interpretation
Parameters of the physical model of the base slab:
· dimensions: length 4 m, width 3 m, thickness 140 mm
· material of a slab: concrete B25, aggregate 5-10 mm
· reinforcement: rod spacing 150 mm, A400 class, diameter 10 mm
· additional elements: 2 hollow transverse steel bars inside the slab
Parameters of the support system:
· total amount of springs: 140
· support spacing: 300 mm
· rigidity of springs: 2 tons/meter
Support system is used to model various soil-structure interaction as:
· increasing and decreasing of reactions at the supports
· modeling an interaction without any particular supports
· modeling of a rigid support
