Exam 3: Loads on Buildings

On a leeward wall, the wind pressure

For wind blowing along one of the two major axes of a rectangular building, the windward wall is subjected to positive (toward- the- wall)pressure.

For most of the United States, the design wind speed for an average- risk building is

What is the role of tectonic plates with earthquakes?

How many earthquakes occur on earth every year?

In which of the following roofs will you consider the effect of rain load?

In a building whose structural system consists of columns, beams, and floor and roof slabs, the columns are spaced at 40 ft on center in one direction and 25 ft on center in the other direction. What is the tributary area for a corner column?

Name the most important factor that affects the wind pressures on building surfaces.

Explain the differences between Wind Exposure Categories B, C, and D.

What is the design wind speed for average- risk building: (a)for most locations in the United States and (b)for coastal areas of the western United States?

Everything else being the same, a building constructed of heavyweight materials is subjected to a greater earthquake load than a building constructed of lightweight materials.

How does the wind exposure classification affect the roof snow load on a building?

What is the weight of 1 sq ft of 1- 1/8 in.- thick OSB sheathing? Density of OSB = 36 #/ft3.

What types of construction are (a)suitable and (b)unsuitable in an earthquake- prone region? Explain your answer, giving reasons.

Using sketches and notes, explain the types of wind pressure that occur on a rectangular building.

Does the roof live load vary with occupancy, similar to floor live load?

The loads on a floor are generally expressed in

The design wind speed is also referred to as the

In terms of snow load, what is a cool roof and what is a warm roof?

Is the weight of a structural element such as a beam, floor, or roof dead load or live load?
