Abstract
Different structural materials possess different characteristics. In order to maximize the respective benefits of different materials, they are often used in combination. The result of this combination is the composite or hybrid systems, which has come to have the specific meaning of steel and concrete components connected together. In this manner, they behave as a single structural unit. In current practice, composite construction is one of the most efficient construction types for multi-story buildings. It can be applied to both lateral and gravity load resistance system. Since buildings of the future will involve a variety of forms, and will be flexible for multiple use spaces, composite construction will enable the designers for their desire to design contemporary tall buildings. This paper is intended to give general information of composite structures employed in multi-story buildings by giving descriptions of a number of buildings related to architectural applications of steel and composite building systems.
