16 April 2004 to enable designers across Europe to practice in any country that adopts the code. Eurocode 8 – Design of structures for earthquake eurocode 2 design of concrete structures pdf, when concrete structures are built in seismic regions.
EN 1992-1-1 deals with the rules and concepts required for designing concrete, reinforced concrete and prestressed concrete structures. Pre-design: Before any other designing is undertaken, the limit states of durability and fire design are considered in order to ascertain the required cover to the reinforcement, the minimum size of members and the appropriate concrete strength. The size of the reinforced concrete element and the quantity of reinforcement to resist bending, shear and torsional forces are determined. Although these initial estimates are likely to change throughout the design, giving considerable amount of thought at this stage is likely to save a lot of time later on.
Ultimate limit states are often more critical for concrete structures. Consequently, when design is undertaken, the ultimate limit state is designed for and then if necessary serviceability is checked for. However, element sizes ascertained in the pre-design stage usually ensure serviceability criteria are met. Serviceability requirements to check for deflection and crack widths are generally satisfied by observing the following details.
Providing not less than the minimum permitted percentage of reinforcement. Limiting the spacing of tension reinforcement. If actual deflections are required, then the structure must be analysed for the serviceability limit state, using design service loads. The deflections obtained will generally be short term values and will be multiplied by a suitable factor to allow for creep effects and to give realistic long term values. EN 1992-1-2 deals with the design of concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1992-1-1 and EN 1991-1-2. This part 1-2 only identifies differences from, or supplements to, normal temperature design. Part 1-2 of EN 1992 deals only with passive methods of fire protection.
Active methods are not covered. EN 1992-1-4 gives a general basis for the design of buildings and civil engineering works in reinforced and prestressed concrete made with lightweight aggregate concrete with closed structure. EN 1992-1-5 gives a general basis for the design of reinforced concrete components provided with unbonded tendons placed within or outside the concrete. In addition, it provides design rules which are mainly applicable to buildings but, does not apply to structures subjected to significant fatigue under variable loads. It does also not apply to structures with tendons temporarily ungrouted during construction.
EN 1992-1-6 provides supplementary rules to the general rules given in ENV 1992-1-1 for the design of components in building and civil engineering works in plain concrete made with normal weight aggregate. EN 1992-2 gives a basis for the design of bridges in plain, reinforced and prestressed concrete made with normal and light weight aggregates. EN 1992-3 complements EN 1992-1-1 for the particular aspects of liquid retaining structures and structures for the containment of granular solids.
