Internet has deeply impacted the economic mode and social behavior of human’s. Recently, internet of things (IoT) inaugurates a brand-new communication pattern that all the objects in our life and work could be possibly communicated in a sensory and intelligent manner. The internet of things provides that same level of connectivity. But, instead of being connections between people, it is connections between devices. Instead of people informing devices, it’s that devices informing people. Today, the technology of IoT has spread into civil infrastructures. Why for instance, is a car carefully designed for easy inspection, containing a wealth of monitoring systems which gives an alert when a repair is needed, but a much more expensive civil engineering structure with expected service life of 100 years is not? The new megatrend, the Internet of Things where the installation of cheap, wireless sensor networks with intelligent software and local computing power, could be used for health monitoring of structures. It is considered that the emergence of smart civil infrastructures on the network of IoT would revolutionize the life style of human’s. Some of most important civil infrastructures connected IoT is introduced in this paper.
