the joints
There are many types of frame structures, such as the Eiffel tower, the frame structures help keep all the pillars so it doesn't all fall apart and destroy everything, a house, and a playground, every structure has frame structures, this is what is called a combination structure. Hope this helps. :)
chairs are shell/solid structures because it is a solid and can be considered a frame
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.
Some structures are combinations of different types of structures:- Football helmets are shell structures - to protect the head, with a frame structure attached in front - to protect the face.- Hydro-electric dams are mass structures, with frame structures inside to house the generators- Airplanes are frame structures, with a 'skin' that acts like a shell - giving it the added strength to resist stresses and making it lightweight and flexible.- Domed buildings combine shell and frame construction- Warehouses are often built with columns to support the roof (frame) and concrete blocks, (mass structures) which stay in place because of their weight.

Examples of some frame structures are scaffolding, a skeleton of an animal or the eiffel tower.
The Eiffel tower and a bike are some. Frame structures are not necessarily only things made of metal and those kind of materials, but also everyday structures like a bed, a chair or a window. A frame structure is something that is made up of a variety of materials that consists of a frame and is filled in from that.
FRAME STRUCTURESFrame structures are structures that are made up of rigid (stiff, firm, difficult to bend) parts joined together to form something called a framework. These parts are known as members. There are lots of examples of frame structures such as a bridge - a bridge is a frame structure that spans a gap, and a bicycle is a frame structure that supports a load such as the mass of a person.SHELL STRUCTURESShell structures contain or protect things from the outside and are usually hollow inside. In a shell structure, the outside layer of the structure holds the whole object together. Examples of shell structures are the mug that holds your coffee, the snail shell which both protects and contains the snail, honeycomb which contains and protects bee's honey and shells of nuts.
