1. When larger dead loads tend to reduce the effects of other loads, what is the recommended factor that is used with the dead load?
a) 0.9
b) 0.8
c) 0.7
d) 0.6
Explanation: 0.9D + 1.6W + 1.6H & 0.9D + 1E + 1.6H are the examples.
2. Load factors do not vary in relation to the seriousness of failure.
a) True
b) False
Explanation: Load factors were developed on the assumption that designers would consider the seriousness of all the possible failure in specifying loads. Load factors are minimum values.
3. In the equation U-0.9D + 1.6W + 1.6H, what is the load factor for H if the structural action of H counteracts that due to W or E?
a) 0.1
b) 0.05
c) 0.005
d) 0
Explanation: H should be included in design resistance here as lateral earth pressure opposes action of other forces.
4. In case of wind and seismic loads, how many times do we have to apply applicable equations?
a) 1
b) 2
c) 3
d) 4
Explanation: Wind and seismic loads can have two values depending upon direction of those forces, and it is possible for the sign of them to be different.
5. 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
Explanation: Rest three types of loads are always applied to buildings.
6. Dead load comprises of:-
a) Permanently attached loads
b) Temporarily attached loads
c) Permanent as well as temporary loads
d) Snow load
Explanation: They include weight of structural frame and that of walls, roofs etc.
7. Live loads, with time can vary in:-
a) Magnitude
b) Position
c) Neither position nor magnitude
d) Position as well as magnitude
Explanation: They are caused by occupancy, use and maintenance of buildings.
8. Most of the loads applied to a building are environmental load.
a) True
b) False
Explanation: Most of the loads are dead followed by live loads.
9. 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
Explanation: Modern buildings with less live load initially have high chances to acquire partition after some years
10. 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
Explanation: Reference period is typically assumed to be around 50 years so as to establish magnitude of ASCE-02 live loads.
