Calculate the total imposed load on a flat roof if it is used for a small gathering with an expected occupancy of 80 people, each weighing 75 kg, plus maintenance equipment weighing 500 kg. Assume the area is 100 m².
💡 Hint: First, convert the total weight into kN by dividing by gravity.
A sloping roof with a slope of 30 degrees experiences wind uplift. If the area of the roof is 150 m² and the wind speed is 20 m/s, calculate the wind load using a standard wind load coefficient.
💡 Hint: Check the wind load coefficient in your reference materials.
