  • As the number of new projects continuously decreases in the domestic construction market, construction companies in South Korea frequently enter overseas projects. Under this situation, domestic structural engineers are required to be able to design buildings in compliance with international standards. Structural engineers in South Korea are generally accustomed to the 2016 Korean Building Code enacted based on US structural design standards (ACI318 and AISC 360). However, they are insufficiently experienced with the other structural standards, including Eurocode, and thereby have difficulties executing overseas construction projects designed in accordance with those standards. In attempts to maximize the characteristic advantages of steel structures and reinforced concrete structures while complementing their limitations, SENVEX CO., LTD. has developed various steel-concrete composite structures. Among the developed structures, the Thin Steelplate Composite (TSC) beam has been verified its performances with regard to resistances of load and fire through experimental research, and multiple patents have been registered thereon. Furthermore, this TSC beam has been applied to various construction projects. With its advantages mentioned above, TSC beam was recently proposed and applied for a large-scale warehouse construction project that was jointly ordered by the Jurong Town Corporation (JTC, Singapore’s urban development corporation). Given that Singapore has designated Eurocode  as its national structural design standards, SENVEX has established the TSC beam design method based on Eurocode. In this article, a design method of the TSC beam based on Eurocode was introduced, which had been established in an attempt to apply the TSC beam to Singapore. To begin with, a brief introduction to the TSC beam was presented along with its structural performance and fire-resistance performance verified by previous experimental researches. Also, major regulations concerning TSC beams from KBC 2016 and Eurocode were summarized. In designing TSC beams, KBC 2016 and Eurocode are similar in that a composite structure-based design is implemented but they differ in many aspects, for example, in terms of the strength reduction factors, the classification system of steel sections and composite sections, the equations for determining the limits of plate width-thickness ratio, and the equations for estimating the flexural strength of the composite section.
