Problem Statement: Tension Development Length (Basic) In RCDC, automatic detailing requires precise calculation of bar anchorage. For a #6 (19mm diameter) epoxy-coated bottom bar in normal-weight concrete, calculate the basic tension development length ($l_d$) using a simplified ACI 318 approximation formula. Given: $f_y = 420$ MPa, $f'_c = 28$ MPa.

Problem Statement: Tension Development Length (Intermediate) Calculate the required development length $l_d$ for an uncoated top bar (cast with $>300\text{ mm}$ of concrete below it). The bar diameter is $16 \text{ mm}$, $f_y = 420 \text{ MPa}$, and $f'_c = 35 \text{ MPa}$.

Problem Statement: Tension Development Length (Advanced) If the calculated development length $l_d$ is $1077 \text{ mm}$ but the available column width to anchor the beam bar is only $600 \text{ mm}$, what is the structural implication and how does RCDC handle this?

Case Study: Transitioning from STAAD Pro to RCDC (Conceptual) You have finished the structural analysis of a 10-story concrete framed building in STAAD Pro. All deflections and base shears are within limits. What is the precise workflow to generate actual reinforcement drawings for the columns using RCDC?

Case Study: Handling Column Design Failures in RCDC (Conceptual) During the Auto Design process in RCDC for a building's columns, a ground floor column fails because it exceeds the maximum reinforcement ratio of 8%. How should you resolve this issue holistically?
