Compatibility Strut-and-Tie Modeling: Part II-Implementation Academic Article

abstract

• This paper presents the implementation and computational validation of a compatibility-based strut-and-tie model (C-STM) presented in a companion paper intended for analyzing the nonlinear force-deformation behavior of disturbed regions and structural concrete deep beams. The C-STM is used to predict the force-deformation response and internal nonlinear strain behavior of previously conducted large-scale reinforced concrete bridge bent-cap experiments. Additionally, the experimental results are compared with current code-based approaches to illustrate how the C-STM can be used as a minimalist computational analysis tool to provide an accurate prediction of the structure's force-displacement response. A comprehensive description of how the C-STM is implemented into structural analysis software SAP2000TM is given to provide a step-by-step modeling procedure that can be replicated by practicing engineers seeking to apply this modeling procedure to other facets of research and design. 2012, American Concrete Institute.
