System to evaluate structural behavior

A system comprising:

• a first accelerometer mounted to a first location of a structure supporting a roadway, the first accelerometer to generate, for each of a first plurality of consecutive time periods, an acceleration value associated with the first location;
• and
• a computing system to:
• determine a first value of a first indicator based on absolute values of the acceleration values;
• determine a plurality of pairs of consecutive-in-time acceleration values of the received acceleration values;
• determine differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
• determine absolute values of the differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
• determine a second value of a second indicator by determining a sum of the absolute values of the differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
• determine a first value of an index based on the first value and the second value;
• identify a structural fault of the structure based on the first value of the first indicator and the first value of the index;
• and
• in response to the identification of the structural fault, activating a barrier on an end of the roadway to prevent traffic from entering the roadway.

A non-transitory computer-readable medium storing program code executable by a processing unit to cause a computing system to:

• receive, for each of a first plurality of consecutive time periods, an acceleration value associated with a first location of a structure supporting a roadway;
• determine a first value of a first indicator based on absolute values of the acceleration values;
• determine a plurality of pairs of consecutive-in-time acceleration values of the received acceleration values;
• determine differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
• determine absolute values of the differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
• determine a second value of a second indicator by determining a sum of the absolute values of the differences between the acceleration values of each of the plurality of pairs of consecutive-in-time acceleration values;
• determine a first value of an index based on the first value and the second value;
• identify a structural fault of the structure based on the first value of the first indicator and the first value of the index;
• and
• in response to identification of the structural fault, activate a barrier on an end of the roadway to prevent traffic from entering the roadway.
