The major challenge in today’s structural engineering is to better design structures against the damaging effects of natural hazards and terrorist attacks. Smart structural systems are an innovative concept that has been proven to be very effective in protecting structures. These systems absorb damaging energy and/or counteract damaging force on the structure, and thus reduce structural response and possible damage. Smart structure technology is being improved every day, and there is a great need for documented references in this field.

Advanced research has discovered natural and man-made materials with unusual properties, called smart materials, and systems that can automatically adjust themselves to environmental changes, called adaptive systems. These discoveries led to the innovative concept of smart structures. A smart material is defined as any material that is capable of being controlled such that its response and properties such as stress, temperature, moisture, pH, electric or magnetic fields can be significantly changed in a controlled fashion by external stimuli. Have classified these materials in several subcategories based on their fundamental properties.

There are a number of types of smart material, some of which are already common. Some examples are as follows:

Shape-memory alloys and shape-memory polymers are materials in which large deformation can be induced and recovered through temperature changes or stress changes (pseudoelasticity). The shape memory effect results due to respectively martensitic phase change and induced elasticity at higher temperatures.

Self-healing materials have the intrinsic ability to repair damage due to normal usage, thus expanding the material’s lifetime. One of the most recent advancement in this field resulted in a new type of concrete named “bioconcrete” which can repair its own cracks. The use of bacterial concrete can in theory lead to substantial savings, especially in steel reinforced concrete.
