Analysis of the Behavior of Steel-Concrete Composite Structures against Dynamic Loads in Multi-Storey Buildings

This study aims to analyze the behavior of steel-concrete composite structures to dynamic loads in high-rise buildings. Steel-concrete composite structures are one of the innovations in the world of construction that combines the tensile strength of steel and the compressive strength of concrete to produce an efficient structural system that is resistant to various types of loads, including dynamic loads such as earthquakes and winds. This study uses a qualitative approach with the literature study method (library research) to examine various previous research results, technical standards, and relevant theories regarding the response of composite structures to dynamic loads. The main data sources come from international journals, civil engineering books, as well as globally recognized composite structure design guidelines. The results of the analysis showed that composite structures have better performance than conventional structures in responding to lateral forces due to dynamic loads, especially in terms of energy dissipation and plastic deformation. In addition, the integration of steel and concrete elements can improve the rigidity of the structure as well as reduce the risk of local failure. However, the effectiveness of these structures is highly dependent on the details of the joints, the method of execution of the construction, and the suitability of the design to the characteristics of the dynamic load. These findings make an important contribution to the development of safer and more efficient multi-storey building structure designs, as well as the basis for further research related to the strengthening of composite structures in earthquake-prone areas.
