MODEL TESTS ON HULL-DECKHOUSE INTERACTION

To check a theory and formula proposed by H. H. Bleich on stress relationship of hull and house for vessels fitted with long deckhouses. Theory based upon concept of separate house and hull bending with interaction strongly dependent upon vertical stiffness of support of house. Nine tests were performed upon a single 20-ft. aluminum model with three separate houses, fitted for simple variation of underdeck stiffness. The hull of double-cell construction, connected by fitted bolts and high-torque bolts with houses 160 and 80 in. in length and demountable main deck equipped with simulated deck beams. Design based upon proportionality of elastic action of ships and model with midship proportions in general conformance with passenger vessel practice. Range of Bleich u value for nine tests representative of ship values to be expected. Model loaded to give constant hogging moment throughout length of house.
