introduction

A framed structure in any material is one that is made stable by a skeleton that is able to stand by itself as a rigid structure without depending on floors or walls to resist deformation. Materials such as wood, steel, and reinforced concrete, are example of this, which are

strong in both tension and compression.

Have you ever thought of the skeleton

of the building as the main factor design,

or do you usually resolve

at the end of the creative process?

definition
Definition

A frame system is one whose principal structural elements consist of beams and columns connected through rigid nodes, forming resistant frames in two main directions of analysis, which enables the transfer of bending moments and axial loads to columns

behaviour earthquakes
Behaviour earthquakes
  • Relative stiffness of beams and columns.
  • The design of connections
  • Some areas exposed to earthquakes the limit can be around 20 floors and high seismic risk zones that limit must be found in about 10 floors.

advantages and disadvantages
Advantages and disadvantages

DISADVANTAGES

  • This type of wet construction is slow , heavy and therefore more expensive.
  • Its flexibility allows large displacements which causes damage to nonstructural elements.
  • Use of this structural system is limited to low and medium structures, because as the building has more floors, have to be greater the size of the columns, which can make the project economically and architecturally unviable .

ADVANTAGES

  • Greater freedom in the distribution of the inner spaces of the building.
  • They are very flexible structures that attract small seismic action.
  • by the use of brick walls in the frame system, the heat transmited to the inside of the building is less than the other structures.

  • Concrete

Structures are the result of a combination or mixture of materials with different characteristics such as concrete and reinforcing steel. In these cases the steel is placed on the bottom because it is the tension zone, later is emptied the concrete.

Wood

WALL

Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls.

slide10

CORNERS

A multiple-stud post made up of at least three studs, or the equivalent, is generally used at exterior corners and intersections to secure a good tie between adjoining walls and to provide nailing support for the interior finish and exterior sheathing

slide13

Steel

Is based on the same principle of wood, but is much simplified by the far greater strength of the material, which provides more rigidity with fewer members. The column and beam are fused by riveting or welding , stresses are distributed between them, and both can be longer and lighter than in structures in which they work independently as post-and-lintel

conclusion
conclusion

The structural configuration can be considered the fundamental aspect in the entire structural design. These conclusions are deduced from the experience gained in past seismic events, showing that well-structured and detailed buildings have satisfactory performance even without undergoing profound analysis and calculations. buildings with frame system has proven to be one of the most resistant to earthquakes and also one of the most flexible spatially.
