... damage increments. The focus is on reinforced concrete structures, where multiple cracks initiate and compete to survive. Findings Compared to nonlinear smeared crack models in incremental‐iterative settings, the sequentially linear model is shown to be robust and effective in predicting...

... Failure (mechanical) Reinforced concrete In case of T60, the predicted maximum load is much lower than the observed one. The reason can be confirmed from the steel strain distribution. The predicted strain distribution coincides with observed one in low load level (50 and 100 kN), but at maximum...
