Skeleton 3D frameworks consisting of pin or welded connection with round or rectangular Hollow section (HSS) are generally designed as space frame. Architects while designing a steel structure are very conscious about of space, shape, forms and esthetic view. Space frame structures are only solution of their worries. A recent review of developments in the field of progress has been made in the field of pre fabricated double layer girds. Two basic elements of space frame structures, the top module in shape of square, Rhombus, Rectangular and Triangular base, along with similar shape bottom module, from a double layer space frame. All the members are made out of various Hollow Steel Section which are connected to one another by Hollow / solid spherical nodes or by welding method.
