Structural Analysis Multiple Choice Questions on “Types Of Structural Loads – 1”.
1. Which of the following structural loads are not applied commonly to a building?
a) Dead load
b) Rain load
c) Live load
d) Environmental load
Answer: b
Clarification: Rest three types of loads are always applied to buildings.
2. Dead load comprises of:-
a) Permanently attached loads
b) Temporarily attached loads
c) Permanent as well as temporary loads
d) Snow load
Answer: a
Clarification: They include weight of structural frame and that of walls, roofs etc.
3. Live loads, with time can vary in:-
a) Magnitude
b) Position
c) Neither position nor magnitude
d) Position as well as magnitude
Answer: d
Clarification: They are caused by occupancy, use and maintenance of buildings.
4. Most of the loads applied to a building are environmental load.
State whether this statement is true or false.
a) True
b) False
Answer: b
Clarification: Most of the loads are dead followed by live loads.
5. Building codes require the partition load to be considered even without partition if live load is less than:-
a) 60 psf
b) 70 psf
c) 80 psf
d) 90 psf
Answer: c
Clarification: Modern buildings with less live load initially have high chances to acquire partition after some years.
6. In the method used to establish the magnitude of live load, what is the reference time period?
a) 30 years
b) 35 years
c) 50 years
d) 60 years
Answer: c
Clarification: Reference period is typically assumed to be around 50 years so as to establish magnitude of ASCE-02 live loads.
7. Impact loads are equal to the sum of the magnitude of the loads actually caused and the magnitude if the loads had they been dead loads.
State whether this statement is true or false.
a) True
b) False
Answer: b
Clarification: Impact loads are equal to the difference between the above mentioned entities.
8. Impact load results from which type of effects of loads applied?
a) Static
b) Dynamic
c) Static and dynamic
d) Neither static nor dynamic
Answer: b
Clarification: For static load, impact effects are short lived.
9. How does an increase in the pitch of the roof affects the amount of load that can be placed on it?
a) It increases
b) It decreases
c) Remains constant
d) Depends upon case
Answer: b
Clarification: As rise increases w.r.t span, load carrying capacity decreases.
10. If R1 = 1.1 and R2 = 1.2, then what is value of Lr(in psf)?
a) 26.1
b) 26.2
c) 26.3
d) 26.4
Answer: d
Clarification: Lr = 20 * R1 * R2.
