Vector Active St.

VECTOR ACTIVE STRUCTURE SYSTEM AMIT DAS

VECTOR ACTIVE SYSTEM • Vector active structure systems are systems of straight linear members, in which the redirection of forces is effected by multi directional splitting of forces into vectors along compressive and tensile elements. • Vector active structure systems are short, solid, straight lineal members(bars), in which the redirection of forces is effected by VECTOR partition, i.e., by multi directional splitting of single forces (compressive or tensile bars).

FLAT TRUSSES • All members and nodes lie within a 2D plane consists of straight members connected at joints. No member is continuous through a joint. • When forces tend to pull the member apart, its in tension and when it compresses it is in compression.

APPLICATION • In Buildings , to support roofs and floors , to span large distances and carry relatively light loads.

• In road and rail bridges , for short and intermediate spans and in footbridges.

CURVED TRUSSES • Curved trusses are trusses which are used to give a particular form to the building. • The material mostly used is steel for such construction. • The form is not organic but is in sections.

SPACE FRAME TRUSS • Space frame truss is a 3D framework of members pinned at their ends. A tetrahedron shape is the simplest space truss, consisting of 6 members which meet at 4 joints. Large planar structures may be composed from tetrahedrons with common edges and they are also employed in the base structures of large free-standing power line pylons.
