chairs are shell/solid structures because it is a solid and can be considered a frame
Shell structures predominantly resist loads on them by direct compression. That is without bending or flexure. Since most materials are more effective in compression than in bending, shell structures result in lesser thickness than flat structures. Please also see the related question below.

Analogous, Turtles and snails have no common ancestor and so they evolved independently of one another from different methods/structures. The Snails shell is secreted by specialised glands in the mantle whereas the turtle shell is modified skin

the shell shape makes it strong.
Shell structures are enclosed and hollow in the middle e.g. a snail shell or a house. Frame structures are open on the sides e.g. a tree or the Eiffel tower.

Shell structures have solid surfaces. They are hollow and there shape is often curved.Eg: Eggs, helmets, conch shell etc.Some of the examples of shell structures are storage tanks (water, oil, gas), domed roofs, and pressure vessels.
It depends... CAN I????? Yeah, the sydney opera house and snail shell.
