Solid structure.
The so-called solid structure can also be called a solid structure, which usually refers to a basic type of structure in which the structural material fills the entire structural space. That is, it is commonly referred to as "solid".Its force is characterized by the fact that the external force is distributed in the entire volume, and the load is borne by the entire volume, which is mainly subjected to pressure.
Typical solid structures are relatively easy to identify, such as the Great Wall wall and lead ball mentioned in the textbook, as well as bridge piers, house foundations, and walls, which are also solid structures.
The pyramid was the tomb of the ancient Egyptian kings, mainly made of huge limestone blocks and some granite stone blocks, with labyrinth-like passages and mausoleums, and is one of the architectural wonders of ancient times. What you said is not very clear may mean that there are empty chambers and passages inside the pyramid, which cannot be considered solid, right? In fact, the physical structure here can be both an overall structure and a local structure, such as buildings, pyramids and other solid structures refer to the wall structure, not the overall structure; The shot put, foundation, river embankment and other whole are solid structures.
I don't know if you know, like reservoir dams, bridge piers, etc., are not solid, they are all hollow, but the walls are solid. We need to understand it correctly, and we can't just stick to definitions. Some students asked what kind of structure a hollow brick wall is, and I think it should also be considered a solid structure, because although it is made of hollow bricks, it conforms to the mechanical characteristics of a solid structure.
