The two options are: Long span secondary beams: Long span primary beams: Web stiffeners may be required around large openings. Elongated or rectangular openings should be located in areas of low shear, e. Isolated openings can be reinforced by horizontal stiffeners, as shown, which increases their resistance to shear by local bending around the openings Vierendeel bending.
Stiffened large web opening in a steel beam Services located through web openings in the beams [ top ]Cellular beams Long span cellular beams with regular circular openings Cellular beams are beams with openings regular spacing along their length. The beams are made by cutting and re welding hot rolled steel sections. The full range of hot rolled steel section sizes is available from which to choose the sizes of the top and bottom chords.
For composite design, the top chord is generally chosen as a lighter section than the bottom chord. Openings for services can be cut into the web, and the sizes of the openings can be designed depending on the forces acting at a point in the span. An example of fabricated beams with circular elongated-circular and rectangular openings is shown. One of the advantages of the use of fabricated beams is that they can be designed to support relatively heavy loads when used as long spanning primary beams.
In this way, the depth of the tapered section is normally in the form of a single linear variation from mid-span to the supports, and the minimum depth at the supports is sized only to provide the required shear resistance. Relatively wide zones for services are provided near to the supports.
An example of tapered beams is shown. The floor slab may be in the form of a precast concrete slab or a composite slab with metal decking either shallow or deep decking may be used. The USFB is manufactured from standard rolled sectionsand is available in increments of 1mm depth. USFBs can economically span up to 10m with structural depths that compare very favourably with R.
As such, they are popular in many sectors including multi-storey office buildings. Shallow composite slabs using steel deck profiles typically of 50 to 80mm depth. The slab depth is usually to mm, depending on the deck depth and fire insulation requirement.
Facade - Wikipedia
Typical spans are 2. Deep composite slabs using steel decking of to mm depth in which the typical slab depth is to mm. Deep composite slabs are mainly used in shallow floor construction for spans of 5 to 9m. Precast concrete slabs generally in the form of hollow-core units of to mm depth with an in-situ concrete slab of 60 to mm depth.
Typical spans are 5 to 10m depending on the depth of the hollow-core units. Composite floors using shallow decking The generic shallow deck profiles used in composite floors are illustrated. During the construction stage, and prior to composite action of the decking and concrete being fully achieved in the normal stage, the decking alone will need to support the load due to wet concrete and construction live loads.

Pattern loading due to the construction sequence should also be considered during the construction stage. During construction, propping to the decking may allow longer spans to be achieved in the normal stage. Propping may be seen as impacting on access and programme and to whether or not to prop the decking should be discussed early in the design process. Props should be left in place until the concrete has reached its design strength.
Modern composite slabs contain re-entrant portions which facilitate attachment of wires for suspended services and ceiling. Trapezoidal profiles are based on a mm rib spacing, and often the cross-section is highly stiffened to improve its bending and composite properties. Reinforcement in the slab provides up to minutes fire resistancebut for longer periods of fire resistance which are unusual in the UKreinforcing bars may be placed in the deck ribs.
Steel decking is installed by craning onto the primary steelwork in bundles and usually man-handling into position. A fall arrest system is installed immediately after the steelwork is erected and before the decking is placed. Completed and decked floors may be used as a safe working platform for subsequent installation of steelwork. For this reason, the upper floor in any group of floors usually three floor levels is often concreted first.
Here it is necessary to analyze one of their works which represents their idea in creating architectural space.
Seeing Through the Facade
For example the design of the National Stadium of Pecan known as the birds nest resembles a giant and consistent shape. When you look at it from a high distance not only it is possible to recognize the circular shape but also it is possible to recognize the network structure loaded on the cage. From the distance the geometric configuration and wise selection of lines are visible but as you get closer they vanish that eventually becomes an apart huge figure.
The components are like irregular beams and stairs resembling an artificial forest. Spatial impact of the stadium is new and fundamental but still simple and intuitive as an old building.
It seems unique and the view and structure are the same. The structural elements in interior spaces in addition to providing the building separator clusters provide proper isolation in order to prepare comfort conditions. It also provides the openness of the spaces from micro sized openings to macro sizes glass walls JavaherianThus understanding the architectural spaces is important in recognizing the architectural spaces from urban spaces and considers the role of structure in these spaces.
In this context, we overview the concept of space within the architecture and describe the link between these elements with their structure. Space and Architecture Space is the beginning and ending of architecture. Thus, the spatial definition, in our terms, is a means criticizing and judging the effectiveness of the architecture.
Space and vacuity are the key factor in architecture and they are considered natural. Because architecture is not just art It is not only the picture of life, or the life we or others have passed.
But it is an environment, a scene Zevi, According to the theory proposed by Marcus Vitruvius Pollio architecture based on combining three elements of performance, stability and beauty of architectural form and must meet all three of these elements are necessarily coincide Vitruvius, Judgment is about the interior architecture Unless this judgment is due to the lack of internal space, "Arch of Tito" or "Trayana" are Out of the architectural history, or since they are considered a volume, they are within the jurisdiction of the history of urban planning.
So it is concluded that the 4 facades of a church or a huge building, no matter how beautiful, they are just some boxes that embrace the architectural gem inside Zevi, Structure Structure is the design of forms with different materials that provides various load bearing on horizontal parts or the roof Falahat et al.
Thus understanding of the structure as well as the architect demands elegance, taste, art and creativity.

Structures are architected before being calculated. Understanding the structure as an architect to understand the subtlety, taste, art and creativity can be calculated Tlbd. Mies van as stated in this connection that the structure of the first real interaction with the architectural space Meiss, It means geometry of the structure to provide the aesthetic and structural levels are considered Hashem pour, Nowadays the structure of the building is presented in architectural designs and also designing the architectural space and sometimes the architecture is born out of structure.
It is clear that being light is one of the main characteristics of modernity and as Foster indicated the weight of the Eifel Tower is less than the air that erects the cylinder surrounding the tower Wilson, Human specific environment is created when it is created by a human made structure.
Whatever than we are capable of doing in this space, because human being can move and determines our reaction to it.
