The ratio between the effective length and the unbraced length of the member measured between the centers of gravity of the bracing members. (NSCP Def. of Terms)
- A.
A. Effective length
- B.
B. Effective length Factor
- C.
C. Eccentric Braced Frame (EBF)
- D.

A fracture Phenomenon resulting from a fluctuating stress cycle. (NSCP Def. of Terms)
- A.
A. stress
- B.
B. strain
- C.
C. deflection
- D.
D. fatigue
Correct Answer
D. D. fatigueExplanation
Fatigue is the correct answer because it refers to a fracture phenomenon caused by a fluctuating stress cycle. When a material is subjected to repeated stress cycles, it can weaken and eventually fail, resulting in a fracture. This phenomenon is known as fatigue. Stress, strain, and deflection are all related to the behavior of materials under load, but they do not specifically refer to the fracture phenomenon caused by a fluctuating stress cycle.Rate this question:

The stress that remains in an unloaded member after it has been formed into a finished product. (NSCP Def. of Terms)
- A.
A. stress concentration
- B.
B. residual stress
- C.
C. shear factor
- D.
D. instability
Correct Answer
B. B. residual stressExplanation
Residual stress refers to the stress that remains in a member even after it has been formed into a finished product and is unloaded. This stress can be caused by various factors such as manufacturing processes, thermal gradients, or material properties. Residual stress can have significant effects on the performance and behavior of a component, as it can contribute to deformation, cracking, or failure under certain loading conditions. Therefore, it is important to consider and manage residual stress in order to ensure the structural integrity and reliability of the finished product.Rate this question:

Correct Answer
C. C. plastic momentExplanation
The correct answer is c. plastic moment. The plastic moment refers to the maximum moment that a fully yielded cross-section can resist before undergoing significant deformation. Once the plastic moment is reached, the material will continue to deform without any increase in resistance. This concept is important in structural engineering, as it helps determine the maximum load that a structure can withstand before it fails.Rate this question:

A method proportioning structural components such that no applicable limit state is exceeded when the structure is subjected to all appropriate load combinations. (NSCP Def. of Terms)
- A.
A. Building Frame System
- B.
B. Mechanism Method
- C.
C. Strength Design
- D.
D. Load & Resistance Factor Design
Correct Answer
D. D. Load & Resistance Factor DesignExplanation
Load & Resistance Factor Design (LRFD) is a method of proportioning structural components in a way that ensures no applicable limit state is exceeded when the structure is subjected to all appropriate load combinations. In LRFD, the loads are multiplied by load factors and the resistances are divided by resistance factors to account for uncertainties in the loads and material strengths. This method provides a more reliable and consistent design approach compared to other methods like strength design or mechanism method. Therefore, the correct answer is d. Load & Resistance Factor Design.Rate this question:

What type of concrete when air-dried weights 1900 kg per cubic meter? (NSCP 5.2.1)
- A.
A. Reinforced Concrete
- B.
B. Air-entrained concrete
- C.
C. Lightweight concrete
- D.
D. Concrete
Correct Answer
C. C. Lightweight concreteExplanation
The correct answer is c. Lightweight concrete. Lightweight concrete is a type of concrete that has a lower density compared to regular concrete. This is achieved by using lightweight aggregates or by incorporating air voids into the mixture. As a result, lightweight concrete has a lower weight per cubic meter, in this case, 1900 kg. Reinforced concrete refers to concrete that is strengthened with steel reinforcement, air-entrained concrete is concrete that has air bubbles incorporated to improve freeze-thaw resistance, and concrete is a general term for the mixture of cement, aggregates, and water.Rate this question:

What is the nominal maximum size of a course aggregate when working with depth of slabs for concreting? (NSCP Sec 5.3.3.2)
- A.
A. Course aggregate shall be no longer than 1/3 the depth of the slab under consideration
- B.
B. Course aggregate shall be no longer than 1/4 the depth of the slab under consideration
- C.
C. Course aggregate shall be no longer than 1/6 the depth of the slab under consideration
- D.
D. Course aggregate shall be no longer than 1/5 the depth of the slab under consideration
Correct Answer
A. A. Course aggregate shall be no longer than 1/3 the depth of the slab under considerationExplanation
The correct answer is a. Course aggregate shall be no longer than 1/3 the depth of the slab under consideration. This means that when working with depth of slabs for concreting, the size of the course aggregate should not exceed one-third of the depth of the slab. This ensures that the aggregate is well-graded and allows for easy workability and consolidation of the concrete, preventing the formation of honeycomb or voids. Following this standard helps to ensure the quality and durability of the concrete slab.Rate this question:

Is a component including its attachments having a fundamental period less than or equal to 0.06 sec. (NSCP 208.20)
- A.
A. Braced frame
- B.
B. Rigid Component
- C.
C. bearing wall system
- D.
D. Flexible component
Correct Answer
B. B. Rigid ComponentExplanation
A rigid component refers to a structural element that does not undergo significant deformation or displacement under load. In this context, if a component, along with its attachments, has a fundamental period less than or equal to 0.06 sec, it implies that it has a high stiffness and is resistant to lateral movement. Rigid components are typically used in seismic design to provide stability and resist lateral forces. Therefore, a rigid component is the correct answer because it meets the criteria specified in the question.Rate this question:

- C.
C. bearing wall system
- D.
D. Flexible component
Correct Answer
C. C. bearing wall systemExplanation
A bearing wall system is a structural component that supports the load of the building. It is typically made of solid walls and has a high level of stiffness and rigidity. Since it is designed to provide stability and resist lateral forces, a bearing wall system would have a fundamental period greater than 0.60 seconds. This is because a longer period indicates a slower response to seismic forces, which is desirable for stability and safety. Therefore, the correct answer is c. bearing wall system.Rate this question:
