New member on rigid ground or existing member

(OP)
Hi Good Day



Firstly I have never done non-suspended slab/beam design before. As shown in sketch above if I have a member with load carrying capacity a that is resting on rigid ground or existing member with load carry capacity b without composite action at the interface (i.e. no friction no interface shear strength at the interface), can I say that my total load capacity is a+b? shall I distribute the load according to their member flexural stiffness (i.e if they have same stiffness, each member both existing and new carries the same amount of load?

Thanks

RE: New member on rigid ground or existing member

Two part answer. Your load will be distributed in the ratio of the stiffness of the two members.
However, when it comes to capacity, the full load carrying capacity of one member may not be utilised unless the weaker member yields.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
