ISO/TC 71/SC 5 - Simplified design standard for concrete structures

This document provides information to perform the design of the prestressed concrete box girder bridge for road that complies with the limitations established in 6.1. The rules of design as set forth in the document are simplifications of more elaborate requirements. Among several erection methods of box girder bridges, the provisions of this document are mainly applicable to full staging method (FSM). Designs and details for new road bridges address structural integrity by considering the following: — the use of continuity and redundancy to provide one or more alternate paths; — structural members and bearing seat widths that are resistant to damage or instability; and — external protection systems to minimize the effects of reasonably conceived severe loads.

The present document refers to the panel-to-structure and panel-to panel connections used for the cladding systems of reinforced concrete frame structures of single-storey buildings, typically precast. They can be used also for multi-storey buildings with proper modifications. The fastening devices considered in the present document consist mainly of steel elements or sliding connectors. Dissipative devices with friction or plastic behaviour are also considered. Other types of common supports and bond connections are treated where needed. The use of any other existing fastening types or the connections with different characteristics than those described in the following clauses is not allowed unless comparable experimental and analytical studies do provide the necessary data and verify the design methodology for the particular type.

This document refers to connections in precast frame systems, either for single-storey or multi-storey buildings. The connections for all orders of joints are considered. Large wall panel and three-dimensional cell systems are not considered. According to the position in the overall construction and of the consequent different structural functions, the seven following orders of joints are considered: a) mutual joints between floor or roof elements (floor-to-floor) that, in the seismic behaviour of the structural system, concern the diaphragm action of the floor; b) joints between floor or roof elements and supporting beams (floor-to-beam) that give the peripheral constraints to the floor diaphragm in its seismic behaviour; c) joints between beam and column (beam-to-column) that ensure in any direction the required degree of restraint in the frame system; d) joints between column segments (column-to-column) used for multi-storey buildings usually for dual wall braced systems; e) joints between column and foundation (column-to-foundation), able to ensure in any plane a fixed full support of the column; f) fastenings of cladding panels to the structure (panel-to-structure) that ensure the stability of the panels under the high forces or the large drifts expected under seismic action; g) joints between adjacent cladding panels (panel-to-panel) possibly used to increase the stiffness of the peripheral wall system and provide an additional source of energy dissipation. Simple bearings working by gravity load friction are not considered. Sliding and elastic deformable supporting devices neither, being all these types of connections not suitable for the transmission of seismic actions. The document provides formulae for the strength design of a large number of joint typologies.

This document applies to reinforced concrete building consisting of load bearing walls of reinforced concrete buildings [such buildings are called reinforced concrete box-shaped wall buildings and (RC wall building)] or to the part of RC wall building which uses both this and other types of structure. This document applies to RC wall building as follows: — RC wall building with 5 or fewer aboveground storeys; — eaves height of 16 m or less; — storey height on each storey of 3 m or less; — on the top storey, the storey height can be 3,3 m or less; — if the roof has a slope, the sum of the storey height of the top storey and the height from the eaves to the ridge of 4 m or less. Deep foundations, such as piles and caissons, and their pile footings and caps, are beyond the scope of this document, and are not covered by it.

This document provides guidelines for the planning, design and construction of a cylindrical tank constructed on the ground with prestressed concrete (PC) for use with potable water tank. This document is applicable to PC tanks for potable water with a capacity of 30 000 m3 or less and the diameter-to-height ratio (D/H) from 1,0 to 3,0. NOTE When designing and constructing a tank not covered by this document (reinforced concrete tanks, underground tanks, elevated tanks, etc.), a designer can refer to this document for common elements where possible.

ISO 15673:2016 provides guidelines for the design and construction of low-rise concrete building structures of small area to be built in the less developed areas of the world. ISO 15673:2016 is applicable to the planning, design and construction of structural reinforced concrete structures to be used in new low-rise buildings of restricted occupancy, number of stories, and area. ISO 15673:2016 can be used as an alternative to the development of a National Concrete Building Code, or equivalent document in countries where no national design codes are available by themselves, or as an alternative to the National Concrete Building Code in countries where specifically considered and accepted by the national standard body or other appropriate regulatory organization.

The purpose of ISO 28842:2013 is to provide sufficient information to perform the design of the structural concrete bridge that complies with the limitations established in ISO 28842:2013. The rules of design as set forth in ISO 28842:2013 are simplifications of more elaborate requirements. ISO 28842:2013 can be used as an alternative to the development of a national concrete bridge design and construction code, or equivalent document in countries where no national design codes are available by themselves, or as an alternative to the national concrete bridge design and construction code in countries where specifically considered and accepted by the national standards body or other appropriate regulatory organization, and applies to the planning, design and construction of structural concrete bridges to be used in new bridges of restricted span length, height of piers, and type.

The purpose of ISO 28841:2013 is to provide sufficient information to perform the seismic assessment and rehabilitation of the structural concrete building that complies with the limitations established in ISO 28841:2013, for both undamaged structures that are deemed not to comply with the required characteristics for an adequate response at a specified performance level, and for structures that have undergone damage under seismic loadings. The rules of design as set forth in ISO 28841:2013 are simplifications of more elaborate requirements. ISO 28841:2013 can be used as an alternative to the development of a building code, or equivalent document in countries where no national design codes are available by themselves, or as an alternative to the building code in countries where specifically considered and accepted by the national standards body or other appropriate regulatory organization, and applies to the assessment of earthquake resistance capability and to the seismic rehabilitation design and construction for existing structural concrete buildings.

ISO 15673:2005 applies to the planning, design and construction of structural reinforced concrete structures to be used in new low-rise buildings with restricted occupancy, number of stories, and area. The purpose of ISO 15673:2005 is to provide a registered civil engineer or architect with sufficient information to design the reinforced-concrete structural framing of a low-rise building that complies with these limitations. The rules of design as set forth in ISO 15673:2005 are simplifications of the more elaborate requirements. ISO 15673:2005 may be used as an alternative to the development of a national concrete building code, or equivalent document, in countries where no national design codes themselves are available, or as an alternative to the national concrete building code in countries where it is specifically considered and accepted by the national standard body or other appropriate regulatory organization.
