a …… is the classic
symbol of protection and security.

Architecture satisfies a basic,
universal human need for a …..
roof
More than any of the other arts, ………. demands structural stability
architecture
The architecture is based on
……..
structural system
There are two basic families of structural systems:
- The shell system.
- The skeleton-and-skin system.
what the diffrences between the shell system and skeleton and skin system
In The Shell System One Building Material Provides Both Structural Support And Sheathing (Outside Covering) Buildings made of brick , stone, or adobe
in the other hand,
▪ The skeleton-and-skin system might be compared to the human body, which has a rigid bony skeleton to support its basic frame and a more fragile skin for
sheathing
We find it in modern ……., with their steel frames (skeletons supporting the structure and a sheathing (skin) of glass or some other light material
skyscrapers
…….., which is really an allround entertainment complex, is almost as famous for its construction difficulties as it is for its extraordinary design.and build as a shell system
the opera house
, the builder constructs the walls by piling layer , upon layer, starting thick at the bottom, getting thinner as the structure rises, and usually tapering inward near the highest point
LOAD-BEARING CONSTRUCTION
1- post and initial
2- dome
3-round arch and vault
This is the simplest method of making a building, and it is suitable for brick, stone, adobe, and certain modern materials.
LOAD-BEARING CONSTRUCTION
why Load-bearing structures tend to have few and small openings (if any) in the walls
because the method does not readily allow for support of material above a void, such as a window opening.
The whole of load-bearing structures may then be topped by a lightweight roof, perhaps of ………
thatch or wood
why in load-bearing structures the construction is stable
because its greatest weight is concentrated at the bottom and weight diminishes gradually as the walls grow higher.
▪……. is the most elementary structural method, based on two uprights (the posts supporting a horizontal crosspiece (the lintel, or beam).
Post-and-lintel construction
The most common materials for post-and-lintel construction are ………
stone and
wood.
why the architect must provide supporting posts at close intervals.in post-intel construction
Since neither has great tensile strength, these materials will yield and cave in when forced to span long distances,
