Analysis of rib-plate response to external loading

Laboratory results were obtained under a concentrated load and under a constant bending moment for a corrugation and rib configuration. There were three different configurations of rib-plate combination - no rib, one rib, and two ribs. The electric strain gages were installed on rib and plate to measure strain. Dial gages were mounted to measure deflection along the longitudinal direction. Load was applied by means of 40 kip, GILMORE loading machine. The composite and non-composite response were studied thoroughly. The section response to the external load varies with the loading. The degree of performance is a ideal measurement to differentiate each individual response. In addition, both normal stress and shear stress transfer has a relation with composite response. Experimental data analysis also discussed about principal stress direction and the stress distribution around the bolt connection. The theoretical analysis of the corrugation is based on the orthotropic plate theory. Deflections are in agreement with the experimental displacements. The theoretical stresses are close to experimental data in no- rib case. Simply-supported end condition and assumption of noncomposite response is a good approach to one-rib and two-ribs configurations.
