|Additional information:||A variety of factors makes an existing reinforced concrete structure stronger than that intended by the designer. One such factor is the invoked interaction between both structural and non structural elements which the designer has not been allowed to consider. In the case of slabs, it is well known that the partial restraint to lateral movement of slab perimeters which is naturally present in in-situ concrete construction is responsible for considerable reserves of strength. Such reserves are more valuable to the assessment engineer than to the designer of new structures owing to the sensitivity of capital investment to small differences in calculated ultimate strength when analysing existing structures. A proper consideration of the residual strength assessment of slabs with corroded reinforcement makes the difference between merely specifying a cleaning/protection system and much more costly courses of action. This paper shows how membrane action may now be conveniently applied to the strength assessment of existing bridge deck slabs and its effect on compensating for the damage to the reinforcement|
