Abstract
Domes are structure which encloses maximum space with minimum surface area and they are economical too. To improve the application function and structural characteristics of single reticulated dome, a hybrid type of dome is proposed. Here a combination of schwedler dome and Diamatic dome with different configuration are used. Eight domes where modelled, including schwedler dome, Diamatic domes and its hybrid domes using ANSYS 16.2 parametric design language (APDL). Eigen value buckling analysis and static analysis is carried out for obtain the structural performance of different dome with same span and height. First hybrid shows good structural performance compare to lattice dome. Hybrid domes are very economical and they show good structural features.
