  • 1.  Seeking Advice regarding Bachelors's final year project.

    Posted 22 days ago

    Greetings of the day everyone !!

    I am currently pusruing 3rd year (B.Tech) and want some advice for my final year project related to structural engineering. I am quite passionate in RC design and I am well equipped with some advanced (M.Tech) courses and software. I am looking for some revelant research topics (Topics related to steel structures and design would also work). I want to integrate both experimental and numberical analysis. Theme of the topic should be revelant to some sort of topics like "Loading on buildings" or "Solutions for developing countries". I am happy to work (online) on some sort of similar project if you are working on it without any sort of stipend/incentives. All I prioritize is learning and explore new research topics.

    PS : I am planning to pursue Masters after my Bachelors.

    Arth,

    In RCC traditionally we design structure as uncracked section and then check deflection as cracked section. Even in dynamic analysis we size the structure to remain uncracked. If you can develop some software to model cracked behavior that will be great. It may require non-linear analysis but there is very little guidance on this topic.

    Hi Arth

    For a Bachelor project the skillful application of advanced r/c software with smeared cracking is already demanding enough. For example, you might do an experimental beam bending test and look into the tension stiffening effect between crack develloping (typically triggered at the postions of stirrups) and match this with other nonlinear constitutive laws of bonding behaviour between concrete and explicitly modelled reinforcing bars. If time permitts, you may look in modelling local weakening dur to rebar corrosion (loss of cross-sectional area). Confer the paper attached.

    For a later master theses there are other interesting topics like transfer of stresses due to aggregate interlock in shear cracks. Present modeld of compression stress fields inbetween shear cracks are based on the simplifying assumption of no stress transfer across shear cracks.

    Kind regards, Martin
