🔍 Key Concepts

• Relationship between floors and longitudinals in ship framing • Definition of a floor that is built in short pieces between continuous longitudinals • Differences between open, non-watertight, intercostal, and lightened floors

💭 Think About

• Look closely at member K and ask: is it continuous across the ship, or does it fit between other continuous members? • Which term is specifically used in ship construction to describe a structural piece that is broken up because another member (like a longitudinal) runs through continuously? • How would a designer describe the framing pattern when longitudinals are continuous and the transverse members are interrupted?

✅ Before You Answer

• Identify whether the longitudinals in the illustration are continuous and whether floor K is broken into segments between them. • Recall which option describes a floor whose continuity is interrupted by other continuous members, rather than describing watertightness or weight reduction. • Make sure you are not confusing a term that refers to watertight/open construction with the term that refers to how the floor is arranged relative to longitudinals.
