Structural Forms

• The building fabric as an envrionmental envelope must be able to safety withstand all the forces to which it will be subjected in tis lifetime . 
• There are 3 basic structural forms : 

1. Skeletal ( or frame ) structure . 
2. Solid ( Or load Bearing wall ) structure 
3. Surface structure . 

A skeletonb or framework which supports all the loads & resist all the forces acting on a building & transfer them to the soil where the building rests . 

Solid ( Or Load Bearing Wall ) Structure 

• The thick load bearing wall acts as both the enclosing & supporting structure . 
• For most high rise buildings , part of the structure ( e.g. lift core wall ) are solid structures to resist lateral loads like wind .
