Abstract

Freeform architecture is gaining importance in recent times because of its architectural importance as well as its structural advantages. Freeform shells eliminate the need for column and its bulky foundations leading to column free space and aesthetically attractive structure. The shell being curved in geometry is strong because of the arch action, membrane action and beam action which resists the applied loads. It can be spanned over a large lengths, eliminating the need for intermediate support. This leads to column free structure with large interior space. In the present study a freeform shell is modeled using AUTOCAD as per IS: 2210-1988 and the analysis has been carried out by finite element method using STAAD Pro in order to obtain the deflection of the freeform shell structure.
