Smart Structures Last Longer
From the word itself, it defines a structure which can adapt to the changing environmental conditions is called smart. The good quality of construction work can be achieved by using smart materials like good quality of concrete, glass, steel, piezoelectric crystal, magneto-rheological fluids etc.
Hence, Smart structures can take care of the structures and resist natural calamities.
FACTORS AFFECTING STRUCTURAL HEALTH
1. DIFFERENTIAL SETTLEMENT
It occurs when a building's piers or foundation settles unequally. Differential settlement occurs when the soil present underneath the structure expands, contracts or shifts away. This may be due to flooding, poor drainage, broken water lines, vibrations from nearby construction or poorly compacted fill soil.
2. EARTHQUAKES AND VIBRATIONS
Earthquakes occur when in Earth's crust, masses of rock slip and slide against one another. This kind of movement is most common along a fault. When pieces of crustal rock slip and move suddenly, they release colossal amount of energy which then propagates through the crust as seismic waves. At Earth's surface, these waves cause the ground to shake and vibrate, sometimes with a great intensity.
3. STRUCTURAL DISTRESS
Office, school, hospital, and parking garage facilities present many forms of structural distress that property owners and managers are forced to confront. Whether it is roof collapse, fire damage, settlement issues, or concrete cracking and spalling, TEC Services, Inc. provides complete structural engineering support.
4. CORROSION OF REINFORCEMENT
When the steel reinforcement gets corroded, the corrosion product occupies more than three times the volume of the original steel. It starts exerting great disruptive tensile stress on the surrounding concrete leading to further cracking, corrosion and more weather access.
5. TEMPERATURE STRESSES
The temperature stresses are a combination of the stresses yielding as a result of change in the specific volume of steel which has undergone martensitic transformation during hardening and the thermal stresses caused by quenching.
ADVANTAGES OF SMART STRUCTURE
Some of the advantages of Smart structure are-
1. It takes less time and expenses in inspections.
2. The response of the structure can be monitored remotely in real time.
3. Performance of the new advanced composite materials can be monitored.
APPLICATION OF SMART STRUCTURE
