The concept of Relaxed Funicularity (R-Funicularity) has been introduced in [2] to deal with the difficulties of designing a shell with a funicular behavior. The R-Funicularity has been defined by using a parameter called generalized eccentricity: a shell is said to be R-Funicular if the generalized eccentricity belongs to an admissibility domain defined in terms of membrane forces N and bending moments M. Here we define an N − M admissibility domain that includes the shell tensile limit force Nt, not previously taken into account. The proposed domain is well described by a new parameter, the effective eccentricity, and is used to control the tensile stresses occurring on shells designed to be R-Funicular and to work under compression.

Abstract
The concept of Relaxed Funicularity (R-Funicularity) has been introduced in [2] to deal with the difficulties of designing a shell with a funicular behavior. The R-Funicularity has been defined by using a parameter called generalized eccentricity: a shell is said to be R-Funicular if the generalized eccentricity belongs to an admissibility domain defined in terms of membrane forces N and bending moments M. Here we define an N − M admissibility domain that includes the shell tensile limit force Nt, not previously taken into account. The proposed domain is well described by a new parameter, the effective eccentricity, and is used to control the tensile stresses occurring on shells designed to be R-Funicular and to work under compression.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
