Question 1

Which of the following loads are NOT permanent (dead) loads?

1. Hydrostatic
2. Uniform
3. Live
4. Concentrated
5. Distributed

Answer 1

1,3

Question 2

Describe a superstructure.

Answer 2

A superstructure is the vertical extension of a building above the foundation.

Question 3

Describe a substructure.

Answer 3

A substructure is the underlying structure forming the foundation of a building

Question 4

What is the purpose of the structural system of a building?

Answer 4

The structural system of a building is designed and constructed to support and transmit applied gravity and lateral loads safely to the ground without exceeding allowable stresses in its members.

Question 5

What are the three basic structural configurations for stabilizing elements?

Answer 5

1. Shear Walls
2. Braced Frames
3. Rigid Frames

Question 6

Which of the following descriptions describes a shear wall?

a) Solid walls, primarily made of reinforced concrete, that resist the application of lateral forces. They are commonly incorporated into the building’s core, stair towers, and other vertical structures.

b) Open triangular frameworks, most often constructed of steel or wood. They can be incorporated into the vertical structures of buildings or be part of exterior wall systems.

c) Depends on extra-stiff connections in the column and beam structural framework to resist the effects of lateral forces. Most often constructed in steel or site-cast concrete.

Answer 6

a)

Question 7

Which of the following descriptions describes a brace frame?

a) Solid walls, primarily made of reinforced concrete that resist the application of lateral forces. They are commonly incorporated into the building’s core, stair towers, and other vertical structures.

b) Open triangular frameworks, most often constructed of steel or wood. They can be incorporated into the vertical structures of buildings or be part of exterior wall systems.

c) Depends on extra-stiff connections in the column and beam structural framework to resist the effects of lateral forces. Most often constructed in steel or site-cast concrete.

Answer 7

b)

Question 8

Which of the following descriptions describes a rigid frame?

a) Solid walls, primarily made of reinforced concrete that resist the application of lateral forces. They are commonly incorporated into the building’s core, stair towers, and other vertical structures.

b) Open triangular frameworks, most often constructed of steel or wood. They can be incorporated into the vertical structures of buildings or be part of exterior wall systems.

c) Depends on extra-stiff connections in the column and beam structural framework to resist the effects of lateral forces. Most often constructed in steel or site-cast concrete.

Answer 8

c)

Question 9

Define static load.

Answer 9

A constant load that does not vary over time

Question 10

Define dynamic load.

Answer 10

A load applied suddenly, often with rapid changes at point of application. Creates inertial forces related to its mass (newtons law).

Question 11

Which of the following are examples of static loads?
