Automated optimization-based generation and quantitative evaluation of Strut-and-Tie models
Xia, Yi; Langelaar, Matthijs; Hendriks, Max (Peer reviewed; Journal article, 2020)Strut-and-Tie modelling (STM) is a well-known approach to design D-regions in reinforced concrete structures. Because the STM method is based on lower-bound analysis, finding a suitable truss-analogy model is the most ... -
A critical evaluation of topology optimization results for strut‐and‐tie modeling of reinforced concrete
Xia, Yi; Langelaar, Matthijs; Hendriks, Max (Peer reviewed; Journal article, 2020)Defining a suitable truss model is one of the most important steps of applying the strut‐and‐tie modeling (STM) method to design D‐regions in reinforced concrete (RC) structures. The truss model is a discrete representation ... -
Optimization-based three-dimensional strut-and-tie model generation for reinforced concrete
Xia, Yi; Langelaar, Matthijs; Hendriks, Max (Peer reviewed; Journal article, 2021)Strut-and-tie modelling (STM) is an effective and widely used method to design disturbed regions (D-regions) of reinforced concrete structures. Among the various steps of STM, finding a suitable truss-analogy model is the ... -
Simultaneous optimization of shape and topology of free-form shells based on uniform parameterization model
Xia, Yi; Wu, Yue; Hendriks, Max (Journal article; Peer reviewed, 2019)In current optimization methods for free-form shells, the shape and topology are usually optimized separately. These methods are based on the assumption that the shape and topology of a shell influence each other only ...
