2. P&T Consultants Pte Ltd Civil & Structural Engineer FOREWORD: * When using Etabs we may recognize that their are 3 options for a Wall/Slab section assignment. They are Shell, Membrane and Plate. * Each type of section has different features. * Since Slab or Wall is main element so its section assignment will has significant effect into our model output. * In this brief doc, we will go through major meanings of each type, what it will affect to our model and some useful recommendations.

Be carefully to check the arrangement of membrane and beams so that loading can be transferred to the correct column and correct quantity similar to load take down by loading area method. 4. For cases where we know that membrane will not work and we wish for our design philosophy to be consistent I.e. ignoring the slab strength, you could always define a shell with a reduced out of plane bending stiffness at locations where the membrane assumption cannot be met.
