2.3. Wrinkled and bent panels

The formation of cold-steel takes into account various shapes and procedures. Wrinkled

Since the first century, panels have been used as curved panels, except recently, panels have shrunk into folds.

It has been developed and widely used in metal arch buildings, such as farms.

Architecture. They are regarded as building envelope and structural system.

Economic design. These corrugated and curved panels usually contain transverse corrugations.

It is used for bending and thinning-stretching the wall steel into a curved shape.

At the same time, it also acts as a torsion member. However, it is difficult to assess the strength.

These are wrinkled and curved panels. A unit of currency in North Vietnam. [20] Provide and

Practice has proved that this is a test method to evaluate the strength of this kind of wallboard.

A compressed corrugated plate may suffer from the interaction between all these plates.

Local buckling mode. Pinata Luo et al. [2 1] developed the general theory of elastic bands.

Study on the influence of interaction by the stability stripping method of finite things

The relationship between compression and behavior patterns after buckling. one

Including extensive parametric studies.
