Effects of creep and shrinkage on the behavior of reinforced concrete gable roof hyperbolic-paraboloids

Shell structures achieve a substantial contribution to their strength from geometry. Likewise, then as a corollary, some shells, will experience significant changes in their strength as a consequence of changes in their geometry that develope in response to loads. The special characteristics of concrete, as an aging viscoelastic material, allow the increase of deflections in time under constant load; in addition, concrete shrinks when drying, and consequently, stress redistributions due to geometric changes take place. It therefore follows that reinforced concrete shells built in certain configurations may experience problems due to time deformations.
