Some basic patterns


Pattern creation by element removal


1. SKELETON FRAMEWORKS

Number of bars interconnected at the nodes

2. STRESSED SKIN SYSTEMS

Using a composition of thin sheet material and ribs is a total

structural system called STRESSED SKIN. It is the structural

system used in aircraft, the space shuttle, unit body

automobiles

3. SUSPENDED STRUCTURES

Form of long-span structure that is subject to tension and uses

suspension cables for support.

TYPES OF SPACE-FRAMES


Large spans can be achieved

Concentrated loads are evenly distributed on the entire

structure

Pleasing decorative appearance

Fast installation at site due to pre-fabricated

components

Very good acoustical properties
