The aim of this PPT is to take an overview of the ‘membranes’ in cable and membrane structures. Before installation on site a membrane has to go through several stages right from design including the steps as form finding, load analysis and design of fabric geometry. The paper also talks about several shapes and forms a membrane can achieve and the principle behind the design of these shapes. Important aspect of membrane structure is availability of membranes in market. This paper accounts various available covering materials in the market and the criteria have to be considered before their installations on the site. Joinery plays a significant role in attaining the required shape and equilibrium. This PPT takes a review of significant junctions in a membrane structure.
