Horizontal Staircase Detail

[psychedomination]

Good day,

In the past, I've designed longitudinally spanning staircases, which require a detail like shown below at the top landing :

However, for horizontal spanning stairs (spanning between walls), is that top detail still recommended for the distribution steel?

I'd say that it's still recommended although it's importance diminishes. Temperature and shrinkage steel is supposed to be developed / spliced for yield strength after all.
