Problem:
A two-level walkway across a hotel atrium is supported by tension hangers at interval of 6200 mm. the specified loads used for designing the hangers are:
- 4.8 kPa live load;
- 2.88 kPa dead load uniformly distributed over the walkway
- 2.10 kN/m dead load acting as line load along the length of each railing on both sides of walkway
Confirm that the uniformly distributed dead load of 2.88 kPa is correct for a normal weight concrete slab of 125 mm thickness. (Normal weight concrete density = 2350 kg/m3)
Note: Please describe comprehensively and provide step by step solution.
