TESTE DEIN WISSEN

What is a structural analysis?

Lösung anzeigen
TESTE DEIN WISSEN

Certain idealizations must be made as to how the members are supported and connected together.

The loadings are determined from codes and the forces in the members and their displacements are found using the theory of structural analysis.

​​​​Why do you use the classical methods?

Lösung anzeigen
TESTE DEIN WISSEN

Grasp the way loads are transmitted through a structure and obtain a more complete understanding of the way the structure deforms under load. Finally, the classical methods provide a means of checking computer results rather than simply relying on the generated output.

How do the beams work?

Lösung anzeigen
TESTE DEIN WISSEN

Primarily designed to resist bending moment. When short with heavy load mainly to resist the internal shear force.

What is a “wide flange"?

Lösung anzeigen
TESTE DEIN WISSEN

Top and bottom flanges to resist applied moment and web to resist the vertical shear V.

Types of beams

Lösung anzeigen
TESTE DEIN WISSEN
  • Tapered or haunched when the cross-section varies to restrict shear forces at the end and the beginning.
  • Built-up” by adding plates to their top and bottom.

What is the shape of the concrete beams?

Lösung anzeigen
TESTE DEIN WISSEN

Rectangular cross-sections, since it is
easy to construct this form directly in the field.

​​​​​What is the difference between a wide flange and a plate girder?

Lösung anzeigen
TESTE DEIN WISSEN

​​​​Girder is fabricated by using a large plate for the web and welding or bolting plates to its ends for flanges.

At the site, they are joined together at points where the girder carries a small internal moment.

TESTE DEIN WISSEN

Why casting reinforcing rods within concrete beams?

Lösung anzeigen
TESTE DEIN WISSEN

Because concrete is rather weak in resisting tension.

TESTE DEIN WISSEN

When a plate girder is needed?

Lösung anzeigen
TESTE DEIN WISSEN

A plate girder is for a very large span and the loads applied are rather large.

What are thin plates or shells?

Lösung anzeigen
TESTE DEIN WISSEN

Thin plates are surface structures made of concrete.
