Smart Materials and new Technologies

Smart materials and control, Nano systems, shape memory alloys and textiles, self assembly structures, color changing paints, energy dissipation and absorption are new concepts in civil engineeringspecial these they have more application in earthquake engineering, some characteristic of smart materialsversus other that made them modified 1-Luminous(transparency ,color change and light emission) 2- thermal(heat transfer and absorption)3-acoustic 4-Kinetic (sound absorption)Energy absorption and production)5-shape memories 6-application in ventilation, . . . with this altering and amending inmaterials properties ,production and control systems for structures such as intelligent civil engineering have developed so dramatically particular during these 2 recent decades. In this paper we introduce smart materials and debate about their advantages and applications and we hope their benefits compare their costs can be economic and change building industry vastly through worldwide
