DYNAMIC SENSOR TABLES

The data for each dynamic sensor is stored in a separate table having the same name as the sensor. These tables have been set up to store the pavement response data from a plane traversing the test section. This is referred to as an Event. The field Event# is the common key between all dynamic tables. This system was set up to reflect the fact that when a plane loads the pavement (an event) only a few of the sensors are actually triggered. There is no need to store the data from non-triggered sensors.

1. Aircraft Tables
These tables store data regarding information known about the plane that created an event .

2. H-bar strain gages
Dynamic Carlson strain gages
The two types of strain gage tables are set up to collect the resulting dynamic strain response of the pavement structure.

3. LVDT Tables
These tables store dynamic vertical displacements collected in the three layers of the pavement structure

4. Event_Records Tables
Specific values from meaningful sensor response (for that event) are stored in these tables.

5. Position Strain Gage Tables
