We used AutoCAD programs to complete the architectural design, of span; and then calculate the required area of steel for each moment. 𝗣𝗗𝗙 | This publication offers a general overview of the design of steel framed buildings to the structural Eurocodes and includes a set of worked examples.
Between these two extremes, the interaction of the frame and cladding establishes a further range of relationships. Buildings of an entirely different character emerge depending on these spatial relationships.
A simple example of a portal-frame structure that is continued outside the building envelope to visual effect is shown in Figure 3. In this case, the perforated cellular beams enhance the lightness of the structure whilst preserving its primary function as a rigid frame.
Basic building physics requirements, in terms of thermal insulation and control of condensation, also have to be addressed, particularly when the frame penetrates the building fabric see Chapter More often than not, it is a simple and singular rhythm derived from the equal spacing of the primary frames.
Various examples of repeated frames to form larger enclosures with increasing complexity are shown in Figure 3. An external framework or skeleton often demands greater attention to detail, but conversely permits greater freedom in choice of structure form, as the structure is no longer dependent on the spatial confines of the internal envelope. Therefore, tension structures find their true expression in external structures refer to Chapter 7.
In other structures, a clearer distinction is made between the external frame and building enclosure, such as by use of masts and cables in tension structures.
The Lufthansa terminal at Hamburg Airport uses a portal frame comprising plated box-sections to create a massive external skeleton Figure 3. Rigid also called fixed or moment-resisting connections Figure 3.
Pinned also called simple connections Figure 3. Semi-rigid also termed partial strength connections. Rigid frames require rigid connections in order to provide for stability at least in one direction. Braced frames are stabilised by vertically oriented bracing, and require only pinned connections. The characteristics of these connections are presented in more detail in Chapter 5 and may be summarised as follows. Moment or rigid connections are used in frames where there is a desire to omit vertical bracing in one or both directions.
The main advantage of rigid frames is that an open space between columns can be created, which offers flexibility in choice of cladding, etc. However, the achievement of full continuity between members at the connection requires an extensive amount of fabrication and, as a consequence, this system is relatively expensive. Nominally simple connections may provide some small degree of rigidity, but this is ignored in structural design and these connections are treated as pinned.
Examples of pinned connections Frame design are cleated, thin or partial depth end-plates, and fin-plate connections as illustrated in Figure 3.
Pinned connections are usually simple to fabricate and erect, and are the least expensive type of connection to produce.
As a consequence, lateral stiffness must be introduced into the frame by other means. Semi-rigid and also partial strength connections achieve some continuity through the connections, but are not classified as full strength, as they do not achieve the bending resistance of the connected members. These forms of connections are illustrated later on in Figure 5. They are used for low-rise frames in which horizontal forces are not so high, or in beams where some end fixity is beneficial to the control of deflections.
They were first developed in the s, and have now become the most common form of enclosure for spans of 20 to 60 m. Portal frames are generally fabricated from hot-rolled sections, although they may be formed from lattice or fabricated girders. They are braced conventionally in the orthogonal direction. In general, portal-frame structures are used in single-storey industrial type buildings where the main requirement is to achieve a large open area at ground level and, as such, these structures may not be of architectural significance.
However, the basic principles can be used in a number of more interesting architectural applications, as illustrated in Figures 3. Also, portal frames can be used in other applications, such as in roof structures for multi-storey buildings, long-span exhibition halls, and atrium structures.
The frame members normally comprise rafters and columns with rigid connections between them. Tapered haunches are introduced to strengthen the rafters at the eaves and to form moment-resisting connections. Either pinned or fixed bases may be used. Roof and wall bracing is essential for the overall stability of the structure, especially 3.
Typical examples of portal-frame structures using hot-rolled sections, fabricated sections and lattice trusses are illustrated in Figure 3. Portal frames generally provide little opportunity for expression but, with care, the chosen details can enlighten the appearance of these relatively commonplace structures.
Other applications of portalised structures are illustrated in Figures 3. The Gateway Arch in St. Louis, Missouri, United States which has stood for over 50 years.
