Parametric Study of Geodesic Dome Subjected to Wind Load For Different Geodesic Frequencies

Abstract

Domes are very popular as per the architectural intent and structural intent due to their aesthetic appearance and higher load carrying capacity. During the medieval era the construction of domes lost the demand due to difficulties in construction and lack of availability of skilled labours. In this research we had studied about the advantages and major aspect of constructing the geodesic structure in the modern architecture. In this paper, comparative study of geodesic structure is worked out for 60 meter diameter and class 1 type division method. Class1 method1 is used for different frequencies like 5V, 10V, 15V, 20V, 25V. Modelling of structure is carried out on CADRE GEO 7.0 software. For the purpose of Analysis and design  STAAD Pro V8i SS5 had been used. |Also Optimization of the structure is been worked out using STAAD optimization tool. In order to study the behavior of geodesic dome ratio of height to diameter of dome kept same as 0.5. This paper takes a look into the combination of impact of wind load for different zones with different geodesic frequencies. In this article, a large-scale geodesic dome performance is studied with non-linear dynamic analysis method also known as time history method.
