Question 1

A ____ has a uniform load evenly distributed over the entire length of the beam and is supported at each end.

Accepted Answer

A simple beam has a uniform load evenly distributed over its entire length and is supported at each end.

Question 2

What type of loads cause a downward motion on each building component?

Accepted Answer

Only gravity causes a downward motion on building components. Lateral, temporary, and moving loads may cause horizontal or vertical motion, but not necessarily downward motion.

Question 3

What type of loads are imposed on a structure from a sudden gust of wind or from an earthquake?

Accepted Answer

Sudden gust of wind or earthquake create sudden and rapidly changing loads on a structure, which are classified as dynamic loads.

Question 4

The symbol ____ is often used to represent the values for dead loads.

Accepted Answer

"DL" stands for "dead load," which refers to the weight of the structure itself and any permanently attached components. It is commonly used in engineering and construction to calculate the total load on a structure.

Question 5

What type of loads are superimposed on the building through its use?

Accepted Answer

Dead loads are the static loads that are permanently present on a building, while live loads are the loads that are variable and imposed on a building through its use, such as people, furniture, and vehicles. Therefore, live loads are the type of loads that are superimposed on a building through its use.

Question 6

To figure the total weight that a wall supports, you should divide the area being supported by the weight.

Accepted Answer

To figure the total weight that a wall supports, you should multiply the area being supported by the weight, not divide.

Question 7

Which exposure includes urban, suburban, wooded areas or other terrain with multiple closely spaced structures that are the size of a single-family residence or larger?

Accepted Answer

Exposure B includes urban, suburban, wooded areas, or other terrain with multiple closely spaced structures that are the size of a single-family residence or larger. This classification is used in various contexts, including insurance, emergency services, and urban planning, to describe areas with a certain density and type of structures.

Question 8

Structures in seismic zone A are most likely to be damaged by earthquakes.

Accepted Answer

Structures in seismic zone A are considered to be at the lowest risk of earthquake damage.

Question 9

The term seismic load refers to stress that results from _____.

Accepted Answer

Seismic load is the stress that results from an earthquake.

Question 10

Finding the weight of a floor is the same as finding the weight of a ceiling, but _____.

Accepted Answer

The answer of Finding the weight of a floor is...

Question 11

Roofs used for sundecks are designed in a manner similar to floors.

Accepted Answer

Roofs used for sundecks are typically designed with a similar structure and materials as floors, with added features such as drainage and waterproofing to withstand outdoor weather conditions.

Question 12

In planning for loads from wind, you must assume the prevailing wind is coming from the north.

Accepted Answer

The prevailing wind direction can vary depending on the location and climate of the area. It is important to consider the specific wind patterns and directions for the location in question when designing for wind loads.

Question 13

The most common live loads are moving, roof, and snow loads.

Accepted Answer

Moving loads refer to any load that moves or changes position, including people, vehicles, and equipment. Roof loads refer to any load that is placed on the roof of a structure, such as HVAC units or solar panels. Snow loads refer to the weight of snow that accumulates on a structure during the winter. Together, these are the most common types of live loads that buildings are designed to withstand.

Question 14

Walls generally average about ___ psf.

Accepted Answer

Walls generally average about 10 pounds per square foot (psf) in weight, which is a common estimate for standard wall construction materials.

Question 15

What type of loads vary from 20 to 40 psf (0.96 to 1.92 kN/m²) depending on the pitch and the use of the roof?

Accepted Answer

Loads that vary from 20 to 40 psf are typically associated with roof live loads, which can be influenced by the pitch of the roof and its intended use. Wind loads tend to be higher than this range, while floor live loads and moving live loads are unrelated to the roof.
