Table 5 Horizontal cyclic loading specimens crack patterns commentary

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

Specimen number

Crack pattern commentary

G03-S03-HV0

The crack pattern observed in the specimen as depicted in Figs. 16 and 17 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

G03-S01-HV1

The crack pattern observed in the specimen, as depicted in Figs. 18 and 19, provides clear evidence of the shear-flexural mode with 45° crack pattern instead of the flexure mode of the top slab and the wall opposite the load cell resulting from the external loading imposed during the experiment

G03-S02-HV1.6

The crack pattern observed in the specimen as depicted in Figs. 20 and 21 provides clear evidence of the flexural mode and concrete bearing hairy cracks of the top slab and the wall opposite the load cell resulting from the external loading imposed during the experiment

G03-S04-HV2.5

The crack pattern observed in the specimen, as depicted in Figs. 22 and 23, provides clear evidence of the shear-flexural mode instead of the flexure mode of the top slab and the wall opposite the load cell resulting from the external loading imposed during the experiment. It is also shown the aggressive top slab collapse
