Abstract | Conventionally, crack analysis of reinforced concrete (RC) members may be
conducted by using the finite element method based on smeared crack model or
discrete crack model. However, both the smeared and discrete representations of
cracks have their own deficiencies. The smear crack model could not realistically reflect
the crack paths and hence could not compute crack widths correctly. Whilst the discrete
crack model is difficult to apply because of the need to adaptively generate discrete
crack elements according to the cracks formed during the loading process. By
transforming and reformulating the smeared crack model, a pseudo-discrete crack
model is developed for finite element implementation. Moreover, the novel crack
queuing algorithm is introduced to simulate the stress redistribution during cracking.
The analysis method allows accurate computation of the crack spacing, widths and
pattern. To verify its applicability and accuracy, the method is applied to analyse RC
tension members in the literature, whereby satisfactory numerical results are obtained.
Furthermore, the cracking behaviour of tension members reinforced with high-strength
steel bars is studied. |
