ANALYTICAL STUDY ON FUNICULAR SHELLS WITH VARYING RISES

Abstract

The construction of buildings has started by using concrete many years ago and from then there hasn’t been much improvement in terms of structural design of buildings. In this project, a new way of designing the structure of building by using funicular shells as roof is explored. Funicular shells are the structural systems, which has a special nature and the load is carried on the curvature of shell. Funicular shells which consists of zero percentage steel reinforcement are used for both flooring and roofing systems. The study aims to investigate funicular shells of varying spans of 1 m to 2 m with varying rises of L/10 to L/20 are analyzed. The results suggest that the L/D ratio plays an important role in the deflection, tensile stress, compressive stress and strain values. The accession in rise of the shell is more advantageous in reducing the deformation values. Conclusions are drawn based on the results produced from the software.
