The roof of the Globe Area, in Stockholm, is a space frame.
A space frame is usually an open, three-dimensional framework of struts and braces which define a structure and distribute its weight evenly in all dimensions. This multi-axial load distribution serves to reduce the member forces and thus leads to lightweight and filigree structures. The system consists of members and nodes with a pin joint or bending resistant connections. The choice of the member length and their angles is linked to the loads which are to be carried. In plan view, they can establish a triangular grid or a quadrangular grid, while in section they can formulate single, double, or triple layers.
As a product, consider the space frames manufactured by Mero Systeme GmbH & Co KG of Wurzburg, Germany. These space frames are delivered to the site as a pre-engineered kit, which is very simple and quick to assemble. Every structure piece can be easily lifted by a single worker, and even the unique space frames system requires only one bolt per joint. No special tools or skills are required. Space frame structures can be remotely pre-assembled so as not to interfere with other site activities, and are easily moveable to the final position required. Unless otherwise demanded, nodes are plated by electro-galvanization while the nuts are plated by hot dipping or electro-galvanization.
Due to their ability to adopt almost any shape, light weight, and ability to span large distances, space frames are used for a variety of applications in the architectural and industrial fields. They can be used for all building envelopes, atriums, facades, canopies, special roofs, and buildings. They are also viable in large scale storage spaces, due to the structure to space ratio they provide.
