Simple Deflection Question 1

The code deflection limit charts for Floor Members simply states:

Live load = l/360
Nothing for Wind
D+L = l/240.

So am I only checking the Live Load deflection and the Load combination (D+L) deflection?

Does my Load combination of D+0.75L+0.75(0.6W)+0.75Lr not need to meet l/240? Or is 0.75L+0.75(0.6W)+0.75Lr considered the "L" in D+L = l/240

Where were wood beams mentioned initially?

Quoting ACI318 Table 24.2.2, For the case of members

Not supporting or attached to nonstructural elements likely to be damaged by large deflections

The only check required is LL deflection of L / 180 for roofs or L / 360 for floors.

The total deflection checks are only required for members

Supporting or attached to nonstructural elements
