Abstract [en]

The Economic, technical and scientific developments have contributed to the emergence of composite structures. Where composite structures between steel and concrete are increasingly increasing in use in the construction industry. The reason for this is due to the system's efficiency in structural, economical and constructional aspects and that engineers can utilize both construction materials. Steel-concrete composite structures are mostly used in buildings and bridges in the form of composite beams, composite floors and composite columns.

Extensive experimental and theoretical studies have previously been conducted on composite structures. It is to provide a better understanding on the behavior of the construction system and its components under applied loading.

In this study, experimental trials and theoretical calculations have been conducted to investigate the load bearing capacity of concrete-filled steel tubes. An important goal of the study has been to investigate the difference between concrete-filled steel pipes with and without the impact of shear studs. Economic and time frames have limited the study to using only scaled samples and only one concrete and steel grade.

The survey comprised a total of three trial series. Series 1 consisted of only steel pipes, series 2 consisted of concrete-filled steel pipes and series 3 consisted of concrete-filled steel pipes reinforced with shear studs. The study is presented with a careful review of theoretical calculations, sample production and experimental trials.

The results show that Series 2 consisting of concrete-filled steel pipes had a characteristic compressive strength of 54,6 kN and a minimum standard deviation of 1,46 kN. By reinforcing concrete-filled steel pipes with shear studs, a characteristic compressive strength of 51,8 kN and a standard deviation of 4,06 kN were obtained. It is a decrease in the characteristic compressive strength value compared with concrete-filled steel pipes without the impact of shear studs. Series 1 with only steel pipes had a characteristic compressive strength of 44,1 kN and a standard deviation of 6,86 kN, which was the highest standard deviation.
