Academic Mentor’s Step-by-Step Approach

The academic mentor guided the student through a systematic and logical problem-solving framework, ensuring clarity at each stage of the structural system.

Step 1: Understanding Load Flow and Structural Behavior

The mentor began by explaining how loads travel from beams to columns and finally to foundations. This conceptual clarity helped the student understand why reactions must be calculated accurately at each stage.

Step 2: Analysis of Simply Supported Beams

• The student was guided to calculate reactions in both axes.
• Bending moments were derived and used to calculate elastic section moduli.
• The mentor demonstrated how to combine effects from both directions to select an appropriate beam section.
• Serviceability deflection diagrams were drawn to confirm acceptable behavior.

Step 3: Roof Beam and Truss System

• Reactions from secondary beams were converted into linear loads for simplification.
• The mentor guided the student in constructing axial force, shear force, and bending moment diagrams.
• Using symmetry, the truss system was solved efficiently.
• These forces were then introduced into the roof beam design, ensuring compliance with Eurocode reinforcement limits for bending and axial compression.

Step 4: First Floor Structural Design

• Steel secondary beams were analyzed for shear, bending, and plastic capacity.
• The mentor explained how to select suitable I-sections from steel catalogs.
• Reactions were transferred to floor beams and simplified into linear loads.
• The floor beams were solved as statically determined systems, followed by the analysis of the mid-support condition and concrete section design.

Step 5: Column and Foundation Design

• Axial force diagrams were drawn for columns to identify critical load combinations.
• Reinforced concrete sections were designed with checks on minimum and maximum reinforcement ratios.
• Finally, reactions at the base were used to design foundations, including sizing and reinforcement detailing.

Outcome Achieved

• A complete and coherent structural analysis of beams, trusses, columns, and foundations
• Correct application of Eurocode design limits
• Logical load transfer between structural components
• Well-structured diagrams supporting analytical results

Learning Objectives Covered

• Structural load analysis and force distribution
• Design of steel and reinforced concrete members
• Interpretation and application of Eurocode provisions
• Development of shear force, bending moment, and axial force diagrams
• Integration of serviceability and strength design criteria
• Engineering judgment in section selection and reinforcement detailing
