This check is for lift core which deep in 15m from surface level & the 15mpa concrete is only 3m for the lift core height. So not checked for bending, as it is bearing fully on ground.
Thanks for the reply all of them. I am checking only for axial loads and nominating a safe distance from the edge to avoid any shear failure during construction. As per Tom reply used that formula in AS3600 and worked out the distance to be 300mm from edge based on loadings.
Thanks for Replying my query. To elaborate the question it is 15MPa blinding concrete temporary back fill for a lift core
For safety i am just providing safe working load at time of construction of that lift core. So we need to evaluate the mass concrete footing with no reinforcement.Once lift...
