The prevalent solutions for covering wide spans are the space frames, known as "double or triple layer”. These structures have reached their practical limits, in as much as span size and attainable cost effectiveness is concerned.
This thesis examines a new approach to this problem, based on the application of infinite polyhedra geometries to space frames. These frames are known as I.P.L space -frames characterized by low density, multi-layer lattices.
Criteria development for the systematic selection of geometries suitable for application as space frames preconditioned this task.
A super-criterion, Structural-Engineering in nature, was developed, as an indicator of the tested space frame "effective efficiency" in comparison with a dual-layer Octatrass frame.
The development of functional-Architectural criteria bears further significance to various topics: spatial partition; ability of mega structures to integrate into existing urban texture, and foremost, inner spaces attributes and capabilities in providing "life support" media to human activities. The search for new lattices was an additional precondition of this work.
Probing directions were designated, and computerized generation and presentation methods were developed. Preference was given to low density arrangements, able to handle wide spans, and simultaneously create large spaces suitable for architectural utilization of a functional nature, as well as orthogonal arrangements.
The population explosion problem and its implications and the increasing urbanization tendency has led to a great demand of "air rights" realization. Apparently, future planning of the urban texture as a multi-functional space will become an unavoidable necessity, if multipurpose utilization is to be realized.
A typical example of this thesis is the “Stadium contained Urban Texture”, which was investigated as a case study. It supports the assumption that the span of the functions defined can be extended by an integration of activities completing each other, with an effective utilization of the same civic services and layouts.
The conceptual projects examined and presented in this thesis provide an inspiration to a new architectural strategy, which will enable a meaningful improvement of the prevalent solutions suggest innovative ideas and extend the definitive levels of conservative standards. Hence, one can expect a marked change in the landscape of future metropolis.
