Abstract

The buildings and transportation infrastructures in the world are maturing rather rapidly, which lead to the maintenance, rehabilitation, retrofit, or dismantling the existing system become future trends rather than new construction. Therefore, concrete structure demolition is increasingly becoming an important issue, as more concrete structures reach their service life and require rehabilitation or replacement. Furthermore, as the bearing capacity of concrete structures are reached, partial or total removal of concrete structures become necessary to utilize the spaces of the cities widely and effectively, as well as to widen the bridge itself to increase the capacity of the transportation system. Therefore, this paper addresses an important topic. It first discusses the factors affecting the selection of concrete structure demolition technologies.
