The Question We have structural analysis programs. Can we make the model (like other conventional bridges) and perform the analysis (as usua...
Introduction Prestressed concrete technology is widely used worldwide in the construction of various structures, especially bridges. Prestre...
Composite Section Analysis Finally we came to the composite section analysis. One of the best examples is from Dr. Gilbert and Dr. Ranzi (Ex...
The limitations of linear static analysis in the seismic design gave rise to non-linear static analysis or Pushover analysis. Pushover analy...
Solving the previous example from full iteration Now it’s time to solve the previous example from full iteration. For simplicity, interactio...
Findings and remarks 1. We can calculate the feasible crack angle ranges for each εx and vu/f’c combination. θ min corresponds to concrete c...
Optimum crack angle θ From the previous example, we can catch that there are some possible crack angle ranges for the given εx and vu/f’c. N...
