Abstract:
Describes a test on a reinforced mortar model of a parabolic cylindrical shell with variable thickness. Deflections and strains were measured for 16 increments of vacuum loading up to failure. Experimental results indicated satisfactory model performance because of the close correlation with theoretical predictions in the working load range. The model exhibited a high safety factor against structural failure. Approximate analyses are presented for the shell diaphragm interaction and for the inelastic shell behavior after cracking and after local yielding.
