How to automesh the slab in etabs: https://youtu.be/TM5SIMu_wQo How to manually mesh the slab in etabs:https://youtu.be/3Kk_NRmz1h8 Difference between shell thin and membrane type slab:https://youtu.be/pJz2a3lj-Mw In this etab tutorial video i have explained the Difference between shell thin and membrane type slab and comparison between shell type slab and membrane and also explained when to use shell and when to use membrane in slab design . Etabs tutorial for shell and membrane difference What is difference between shell thin and membrane What is difference between shell thick and membrane Stiffness of slab shear and moment is slab How to see shear forces in slab How to see moment in slab How to check deflection in slab Membrane vs shell type slab When to use membrane When to use shell Membrane type Slab properties list : No moment in slab No shear in slab Slab flexural stiffness is zero Transfer all moment/Shear to supporting members No displacements/rotation results Cannot be auto-meshed Un-Realistic(highly conservative design of supporting members i.e Usually used in beam design as it transfers all forces) If manually meshed then it changes load transfer pattern making it more un-realistic Cannot be used when designing slab Property modifiers incorporating cracked moment of inertia cannot be applied Shell type Slab properties list : Takes moment in slab Takes shear in slab Slab flexural stiffness is considered First it absorbs considerable amount of moment/shear then transfers forces to supporting members Displacements/rotation results at nodes (meshing mandatory Refer video part 1 and 2 –Link in description) Can be auto-meshed Realistic as slab has stiffness Meshing refines results without changing load transfer pattern Can be used when designing slab Property modifiers incorporating cracked moment of inertia can be applied Etabs tutorial #etabs #tutorial #engineering
