Tiivistelmä
Composite columns are often used in structures due to the ease and speed of erection, and high performance in fire situation. Concrete filled tubes are steel tubes that are in site filled with reinforced concrete. In normal situation column works as composite while in fire situation majority of the load is carried by the reinforced concrete core. There are numerous publications about this type of columns but all of them use very simplified methods. Especially regarding the calculation of the neutral axis of circular columns. Also the shear resistance of the column is often omitted.
The reason for this document is to present the calculation of concrete-filled tubes in details. Also to investigate the influence of the bars arrangement in circular columns on their bending resistance. Calculations have been carried for ambient and fire temperatures.
This report includes calculation examples and results in different design situations, for a number of various column cross-sections.
