Abstract
This paper presents the construction regulations and regulations for the design and analysis of coupled columns. Composite columns are composite materials made up of several components such as concrete, steel and reinforcement, while using the rationally positive aspects of concrete as a pressure load and having a part in increasing the fire resistance of the section and steel as reinforcement or a rigid core, which accept loads of pressure and tension also has a great role in increasing the fire resistance of the section and also with adhesion between concrete and steel in the section, a rational solution for the design of modern structures is possible. The trend of innovations in construction requires modern solutions, one of them is the coupled construction system, which also requires greater analysis. In terms of the practice of application and performance of coupled structures, due to the problem that is not sufficiently researched, the largest number of designers claim either reinforced concrete or steel sections in appropriate classical reinforced concrete or steel structural systems. Available literature and practical applications are very few. They are mostly studied in Eurocode 4, and their expressions and explanations are the basis of other regulations from Japan, China, Russia, USA, India, Australia, United Kingdom, Germany, Italy, Ethiopia, Canada, etc. which have an almost similar concept of analysis according to Eurocode 4. The paper shows comparisons of regulations and building regulations for the design of coupled columns as part of the coupled construction system with pictures, diagrams and empirical beams and shows the most applied concept of analysis of coupled columns as well as the simplified method of analysis according to Eurocode 4.
