A Report on the Innovation of 1.5-Layer Space Frames

The present paper introduces a new structural system, "1.5-Layer space frame", which is categorized as a type of space frame with unique geometrical and structural characteristics. A 1.5- Layer space frame is a bar-linked structure configured with one-layer of chords and diagonal members. Unlike a conventional double layer space frame, the 1.5-Layer space frame has no lower chords, or when it is oriented upside down, no upper chords. And unlike a single layer space frame, diagonal members are mounted onto the latticed surface and efficiently strengthen it so that the entire structure can be designed with pin joints and constructed in subtle curvatures or as a plane.
