(e.g. the effects of tolerances and residual stresses from welding). Part 1-10: Material Toughness and through-thickness properties EN 1993-1-10 provides the guidelines for the selection of steel for fracture toughness and through-thickness properties of welded elements where there is a significant risk of lamellar tearing during the fabrication process. Part 1-11: Design of Structures with tension components EN 1993-1-11 gives design rules for structures with tension components made of steel which due to their connections are adjustable and replaceable. These components due to their adjustability and replaceability properties are mostly pre-fabricated delivered on-site and installed into the structure as a whole. Non adjustable and replaceable components are out of the scope of EN 1993-1-11. Part 1-12: High Strength steels EN 1993-1-12 gives rules that can be used in conjunction with all the other part of EN 1993 to enable steel structures to be designed with steel of grades greater than S460 up to S700. Part 2: Steel Bridges EN 1993-2 gives a general basis for the structural design of steel bridges and steel parts of composite bridges. It gives provisions that supplement, modify or supersede the equivalent provisions given in the various parts of EN 1993-1. This standard is concerned only with the resistance, serviceability and durability of bridge structures. Other aspects of design are not considered. Part 3-1: Towers, masts and chimneys EN 1993-3-1 applies to the structural design of vertical steel towers, masts and chimneys, and is concerned only with their resistance, serviceability and durability. Part 3-2: Towers, masts and chimneys - Chimneys EN 1993-3-2 applies to the structural design of vertical steel chimneys of circular or conical section. It covers chimneys that are cantilevered, supported at intermediate levels or guyed. It is concerned only with the requirement for resistance (strength, stability and fatigue) of steel chimneys. The term Chimney is used to refer to: chimney structures, steel cylindrical elements of towers, steel cylindrical shafts of guyed masts. Part 4-1: Silos EN 1993-4-1 provides principles and application rules for the structural design of steel silos of circular or rectangular plan-form, being free standing or supported and is concerned only with the requirements for resistance and stability of steel silos. Part 4-2: Tanks EN 1993-4-2 provides principles and application rules for the structural design of vertical cylindrical above ground steel storage tanks for liquid products with the following characteristics: characteristic internal pressures above the liquid level not less than
