Please let me know more about ULS and SLS of Structural Loads and Load Combinations (NBCC), so that I can go through the details?

On your reference I will provide you details of Structural Loads and Load Combinations (NBCC), ULS and SLS structural loads so that you can get idea.

Here are some information

Structural Loads
Ultimate Limit States (ULS)
Include exceeding the loading-carrying capacity, overturning, sliding, and fracture.

Serviceability Limit States (SLS)
Include deflection, vibration, permanent deformation and local structure damage such as cracking.

D ...... Dead load - a permanent load dure to the weight of building components.
E ...... Earthquake load and effects - a rare load due to an earthquake.
H ...... a permanent load due to lateral earth pressure.
L ...... Live load - a variable load due to intended use and occupancy.
P ...... Permanent effects caused by pre-stress.
S ...... Variable load due to snow, including ice and associated rain.
T ...... Effects due to contraction, expansion, or deflection caused by teperature change, shrinkage, moisture change, creep, ground settlement, or a combination thereof.
W ...... Wind load - a variable load due to wind.

Load Combinations for ULS
Case Principal Loads Companion Loads
1 1.4 D -
2 (1.25D or 0.9D) + 1.5L 0.5S or 0.4W
3 (1.25D or 0.9D) + 1.5S 0.5L or 0.4W
4 (1.25D or 0.9D) + 1.4W 0.5L or 0.4S
5 1.0D + 1.0E 0.5L + 0.25S
