Structural framing needs to be designed for loads that fulfill client’s performance requirements, to transfer loads stably through proper load paths, and to fulfill code requirements for spans and headroom heights for the specific type of usage.
Vertical loads
1. Live loads based on the specific type of use
2. Superimposed dead loads (floor finishes, non-structural partitions, ceilings, and services)
3. Fixed equipment loads
4. Soil self-weight
5. Dead load or self-weight of the structure
Horizontal Loads
1. Lateral wind loads that should be distributed at center of mass
2. Soil, surcharge, and water loads
3. Notional horizontal loading (loading that are used for structural stability of column and walls)
4. Seismic loads
Some loads that affect the internal stresses of the structural members are not considered in design calculations include temperature, expansion, shrinkage, contraction, inertial, and support movement forces.
Load Combinations
LC1: 1.4DL + 1.6LL
LC2: 1.4DL + 1.4WL
LC3: 1.2DL + 1.2Ll + 1.2WL
DL = Dead Load
LL = Live Load
WL = Wind Load
Note: Superimposed dead loads (SDL) should have the same factor of safety as that of dead loads.
