The structural frame must have enough strength to securely bear the gravity loads throughout the entire life span of the building..
An adequate load bearing system is based on a continuous load path throughout the structure:
- The slabs carry the floor loads of each storey.
- The beams carry the loads transferred to them by the slabs as well as the weight of the walls seated on them.
- The columns carry the beam loads and they transmit them to the foundation.
- The footings (foundation) carry the column loads and transfer them to the ground.
