EN 1991
In the Eurocode series of European standards (EN) related to construction, ''Eurocode 1: Actions on structures'' (abbreviated EN 1991 or, informally, EC 1) describes how to design load-bearing structures. It includes characteristic values for various types of loads and densities for all materials which are likely to be used in construction. Eurocode 1 is divided into a number of parts. Part 1-1: Densities, self-weight, imposed loads for buildings EN 1991-1-1 gives design guidance and actions for the structural design of buildings and civil engineering works including some geotechnical aspects for the following subjects: # Densities of construction materials and stored materials. # Self-weight of construction works. # Imposed loads for buildings. Part 1-2: Actions on structures exposed to fire Part 1-2 of EN 1991 deals with thermal and mechanical actions on structures exposed to fire. It is intended to be used in conjunction with the fire design Parts of EN 1992 to EN 1996 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural Robustness
Robustness is the ability of a structure to withstand events like fire, explosions, impact or the consequences of human error, without being damaged to an extent disproportionate to the original causeas defined in EN 1991-1-7 of the Accidental Actions Eurocode. A structure designed and constructed to be robust should not suffer from disproportionate collapse (progressive collapse) under accidental loading. Buildings of some kinds, especially large-panel systems and precast concrete buildings, are disproportionately more susceptible to collapse; others, such as in situ cast concrete structures, are disproportionately less susceptible. The method employed in making a structure robust will typically depend on and be tailored to the kind of structure it is, as in steel framed building structural robustness is typically achieved through appropriately designing the system of connections between the frame's constituents. Design considerations Three alternative measures are used, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Committee For Standardization
The European Committee for Standardization (CEN, french: Comité Européen de Normalisation) is a public standards organization whose mission is to foster the economy of the European Single Market and the wider European continent in global trading, the welfare of European citizens and the environment by providing an efficient infrastructure to interested parties for the development, maintenance and distribution of coherent sets of standards and specifications. The CEN was founded in 1961. Its thirty-four national members work together to develop European Standards (ENs) in various sectors to build a European internal market for goods and services and to position Europe in the global economy. CEN is officially recognized as a European standards body by the European Union, European Free Trade Association and the United Kingdom; the other official European standards bodies are the European Committee for Electrotechnical Standardization ( CENELEC) and the European Telecommunic ...

Construction
Construction is a general term meaning the art and science to form Physical object, objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:decommission, ...

EN 1992
In the Eurocode series of European standards (EN) related to construction, '' Eurocode 2: Design of concrete structures'' (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy. It was approved by the European Committee for Standardization (CEN) on 16 April 2004 to enable designers across Europe to practice in any country that adopts the code. Concrete is a very strong and economical material that performs exceedingly well under compression. Its weakness lies in its capability to carry tension forces and thus has its limitations. Steel on the other hand is slightly different; it is similarly strong in both compression and tension. Combining these two materials means engineers would be able to work with a composite material that is capable of carrying both tension and compression forces. Eurocode 2 is intended to be used in conjunction with: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EN 1996
In the Eurocode series of European standards (EN) related to construction, ''Eurocode 6: Design of masonry structures'' (abbreviated EN 1996 or, informally, EC 6) describes how to design buildings and civil engineering works, or parts thereof, in unreinforced, reinforced, prestressed and confined masonry, using the limit state design philosophy. It was approved by the European Committee for Standardization (CEN) on 23 June 2005. EN 1996 deals only with the requirements for resistance, serviceability and durability of masonry structures and is divided into the following parts. Part 1-1: General - Common rules and rules for buildings In EN 1996-1-1, the basis for the design of buildings and civil engineering works in masonry is given, which deals with unreinforced masonry and reinforced masonry where the reinforcement is added to provide ductility, strength or improve serviceability.

Bridge Design
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
