“…On the other hand, the finite element method has become, in recent years, a powerful and useful tool for the analysis of a wide range of engineering problems. According to Abdollahi [3], a comprehensive finite element model permits a considerable reduction in the number of experiments. Nevertheless, in a complete investigation of any structural system, the experimental phase is essential.…”

2This paper studies the non-linear dynamic behaviour of the steel-concrete composite, curved box beam by using the finite-element method. A three-dimensional finite-element model has been developed to obtain natural frequencies and mode shapes. A parametric study was also conducted to evaluate dynamic behaviour of composite, curved box beams. The results indicate that the frequencies of the composite box beam decreases slightly with an increase in the stud spacing (pitch of shear connector), but the frequencies and mode shapes change significantly when the stud spacing exceeds the double stud spacing (two times the pitch of the full shear connection). This tendency is particularly obvious in the extend mode shapes.

“…All the tested RC frames are simulated numerically through effective two-dimensional finite element (F.E.) models, which are able to follow the highly non-linear nature of the problem (Abdollahi 1996, Rabczul et al 2005, Wang et al 2008). More specifically, appropriate two-dimensional finite elements are employed, which allow the detailed simulation of both the RC and steel link elements.…”

The use of steel bracing systems is a popular method for the strengthening of existing reinforced concrete (RC) frames and may lead to a substantial increase of both strength and stiffness. However, in most retrofitting cases, the main target is the increase of the energy dissipation capacity. This paper studies numerically the efficiency of a specific strengthening methodology which utilizes a steel link element having a cross-section of various shapes, connected to the RC frame through bracing elements. The energy is dissipated through the yielding of the steel link element. The case studied is a typical one bay, single-storey RC frame, constructed according to older code provisions, which is strengthened through two different types of link elements. The presented numerical models are based on tests which are simulated in order to gain a better insight of the behaviour of the strengthened structures, but also in order to study the effects of different configurations for the link element. The behaviour of the strengthened frames is studied with respect to the one of the original bare frame. Moreover, the numerically obtained results are compared to the experimentally obtained ones, in order to verify the effectiveness of the applied simulation methodology.
