Abstract:
The strut-and-tie model (STM) for structural concrete design is still not widely used despite the considerable progress made. To promote its use, this paper presents a refined automatic generation of a proper STM that reduces the input required by the user and facilitates its implementation. This tool is intended to assist in decision-making for the design process, where engineering judgment is relevant. Based on the results presented in the paper, including a comparison with other models recommended in the literature, it is concluded that an automatic determination of the STM can be applied for the analysis of plane reinforced concrete members of both simple and complex geometry.
