IRS srl and National Instruments are the winners of "Automazione Industriale Award 2015 - Category Utility". The winning project is a smart city solution: Structural Health Monitoring network of a cultural heritage structures in Verona. The project adopted IRS platform for structural monitoring Structural-X. It is a product specifically suited for long term and in situ applications based on hardware and software from National instruments.

and private buildings,
bridges and towers.
1. Introduzione
5. PROBLEM STATEMENT
Structural design or assessment,
Damage detection and assessment,
Maintenance and retrofitting of existing structures, structural control during earthquakes
(using semi-active systems).
Historic buildings, due to their structural features, construction techniques and used
materials, are particularly vulnerable to earthquake actions;
STRUCTURAL HEALTH MONITORING (SHM)
Continuous or short/medium-term controls of quantities related to the structural behavior
connected to the evaluation of their evolution with the passing of time;
2. Monitoraggio

6. On-site testing and monitoring can be considered key activities for a conscious knowledge-
based approach in the conservation of the architectural heritage.
INVESTIGATIONS Structural behaviour
definition (ex: validation of behavioural models)
MONITORING Permenent structural controls
(continuous on site inspections)
STATIC MONITORING DYNAMIC MONITORING

NI is unique in that it's providing a common platform for the engineering industry and it’s a platform-based approach that will be necessary to create the engineering systems of tomorrow.
Our approach leverages holistic development solutions and commercial off-the-shelf hardware. Because our platform is modular and reconfigurable, it ensures that the system is scalable and extensible for changing needs, technology trends and multiple applications.

STATIC MONITORING
Measurement of static time-dependent parameters that vary slowly
Controls of: crack pattern, activation of collapse mechanisms, state of stress and strain, variation of environmental parameters, ...
Local controls and damage identification
Measurements of ambient vibrations or exceptional events (e.g. earthquakes)
Identification of dynamic time-dependent parameters (modal parameters)
Continuous, trigger-based or punctual
Global controls and damage identification
STRENGTHENING NEEDS AND VULNERABILITY ASSESSMENT
Increase the knowledge on the structural behavior using shm to assess strengthening needs and avoid the execution of unnecessary interventions
INCREMENTAL APPROACH/INTERVENTION ASSESSMENT
Application of an incremental approach to the execution of strengthening interventions using shm before, during and after the
implementation, validating eventually their effectiveness
