>>> STRUCTURAL CONCEPTUALIZATION Mechanics The study of objects at rest or in motion that are subjected to forces Statics – the study of objects subjected to forces that remain in static equilibrium – buildings fail when there is no static equilibrium Building Configurations – ideally structurally symmetrical, less reentrant angles, near the center of gravity – best geometry: circle (all points equidistant from center of gravity) Strength of Materials The study of the internal effects of external forces MECHANICS Fluid Mechanics Deformed Body Mechanics Rigid Body Mechanics The primary concern of architecture.

Can be concurrent, parallel, non-concurrent & non-parallel Forces that occur on 3 axes. Can be concurrent, parallel, non-concurrent & non-parallel Load that is applied parallel to the length of the member/object. It induces compression OR tension. Load that is applied perpendicular or transverse to the length of the member/object. It induces shear, bending, and/or torsion. Vector sum of the external forces must be equal to zero. Total torque or moment acting on then object must be equal to zero.
