CLOSED-FORM SOLUTION OF SEMI-SPHERE CONCRETE SHELL UNDER LATERAL LOAD

Closed-form solution is one of the exact and reliable approaches in analysis of structures. Here, a semi-sphere shell under lateral load (equal to earthquake load), based on theory of shells and plates, has been studied. Internal forces are present in closed-form. In this study, materials are assumed to be isotropic, homogenous and elastic and the shell acts as a membrane. The outcome of this analysis can be used in studying the behavior of revolutionary shells under lateral load.
