This shear-load transfer mechanism occurs when cracks grow and cut across longitudinal reinforcements,providing an increase into the mechanical shear strength.Then,the crack lips transfer shear stresses to reinforcements.As a result,a local bending and shear at reinforcements are observed.Chapter (3) Ultimate Bearing Capacity of ShallowSo,local shear failure can be considered as a transitional phase between general shear and punching shear.Because of the transitional nature of local shear failure,the ultimate bearing capacity could be defined as the firs failure load (q s,5) which occur at the point which have the first measure nonlinearity in the load/unit area-California Code of Regulations,Title 8,Section 453 Transportation Tank A tank permanently installed on a truck,trailer,or semi-trailer used to transport a product over the highway.Trap Tank (Trap Wagon) A tank mounted on wheels for off-highway use and having a capacity of 1200 gallons or less and used to transport LP-Gas from a storage tank to a mobile fuel tank.
