1. Introduction
Steel-concrete composite beam/slab construction is common practice in bridges and multi-storey buildings due to the combination of compressive strength of concrete and tensile strength of steel [12]. The two components are often secured by shear connectors that greatly influence its strength and ductility [15]. Despite its popularity in these types of constructions, composite members are still a subject of continuous development [16]. One of the areas of interest in the development of composite structures is the shear connectors that bond concrete and steel [16]. Interests in these developments are however limited due to the high cost in setting up in a laboratory environment [8]. Even though the costs of these experiments are monumental, researchers still manage to set up experiments with good results such as conducted by Wang et al. [20] and Alderighi and Salvatore [1] in multi-level framed buildings. A review of literature shows that research on steel-concrete composite structures has focused behaviour of push-out tests at ambient temperature and at elevated temperature. Push-out tests of composite structures at ambient temperature showed that their strength and ductility were often influenced by their material properties [8,10]. Galjaard and Walraven [10] conducted push-out tests for five different shear connectors: headed studs, continuous perfobond strip, oscillating perfobond strip, waveform strip and T-connector. Similarly, Baran and Topkaya [3] conducted an experimental study on another type of shear connector: channel type shear connector or C-channel. The tests aim was to determine the strength of different sizes of C-channel as shear connector in steel-concrete composite structure [3]. Push-out tests on steel-concrete composite structures utilising headed studs were also conducted at elevated temperatures by Zhao [21], Mirza and Uy [15], Anderson [2], Wang [19] and Imagawa et al. [13] among others. Push-out tests on steel-concrete composite structures utilising continuous perfobond strip [16] and T, T-block and Tperfobond [17] have also been conducted at elevated temperatures. Most of the research on push-out tests of steel-concrete composite structures focusses on the behaviour of specimens at ambient and elevated temperatures. A review of other types of composite structures such as the concrete-filled steel tubular columns shows that their strength after exposure to fire can be predicted through the development of mechanics models [11]. Future research will focus on the use of post-fire mechanical properties of shear connectors and concrete to predict the post-fire behaviour of steel-concrete composite structures.
