Table 6 Corroded specimens crack patterns commentary

From: Experimental investigation on corroded and non-corroded RC tunnels under different loading conditions

Specimen number

Crack pattern commentary

G04-S05 (6.3%)-VCO

The crack pattern observed in the specimen, as depicted in Figs. 24, 25, 26, 27 and 28, provides clear evidence of the flexural mode of the top slab resulting from the external loading imposed during the experiment

G04-S06 (13.4%)-VCO

G04-S07 (13.5%)-VCO

G04-S08 (23.4%)-VCO

G01-S01 (4.1%)-HVO

The crack pattern observed in the specimen, as depicted in Figs. 29 and 30, provides clear evidence of the flexural mode of the top slab resulting from the external loading imposed during the experiment

G01-S03 (10.2%)-HVO

The crack pattern observed in the specimen, as depicted in Figs. 31, 32, 33 and 34, provides clear evidence of the flexural mode of the top slab and the wall opposite the load cell resulting from the external loading imposed during the experiment

G04-S02 (12.0%)-HVO

G04-S04 (19.4%)-HVO

The crack pattern observed in the specimen, as depicted in Figs. 35 and 36, provides clear evidence of the flexural mode of the top slab resulting from the external loading imposed during the experiment
