Challenge Problems
Push your limits with advanced challenges
Given a simply supported beam with a span of 10 meters and a concentrated load of 20 kN at its midspan, calculate the required area of steel reinforcement to prevent flexural failure, assuming a concrete compressive strength of 25 MPa and tensile strength of 2.5 MPa.
💡 Hint: Use the equation for bending moment: M = WL/4 for concentrated load.
Analyze an existing beam that has started to show flexural cracks. Propose a remedial strategy for enhancing its structural integrity for future uses.
💡 Hint: Think about rehabilitation techniques used in construction.
