Lecture 15, 30.01.2025 Additional test - retake test

You have to send the solution by 13:00. 

Select the tool you find the best for solving the problem described below. Prepare calculations and the source file with your calculation upload as a solution (the calculation of the quantities must be described understandably).

You must order the materials for the 7-floor building (only the amount for reinforced concrete frame structure elements).  Each floor is repeatable and consists of:

  • 6 columns (rectangular cross-section, 0.3x0.3x4m)
  • 1 slab (6x12x0.3m)

You need to calculate the volume of concrete as well as the necessary reinforcement and the total cost of the materials

Reinforcement for 1 column: 

  • 4 bars with a diameter of 20 mm and length 4.6 m 
  • 24 m of the bar with a diameter of 6 mm

Reinforcement  for 1 slab : 

  • 60 bars with a diameter of 12 mm and length 6.6 m 
  • 30 bars with a diameter of 8 mm and length 12 m 
assume:

  • a ton of steel costs 6,000 PLN,
  • the density of steel is 7 900 kg / m³
  • the price of concrete is 500 PLN / m³
