Cala Galdana Bridge
The Cala Galdana Bridge is a steel arch bridge over Algendar Creek on the island of Menorca, Spain , image_flag = Bandera de España.svg , image_coat = Escudo de España (mazonado).svg , national_motto = ''Plus ultra'' (Latin)(English: "Further Beyond") , national_anthem = (English: "Royal March") , i .... It is the first vehicular bridge constructed in duplex stainless steel. In 2003 its owner (the Consell Insular de Menorca) decided to replace the existing structurally deficient, reinforced concrete bridge due to severe corrosion (due to the marine environment) and settlement in one of its supports. The total length of the bridge is , and its main span is long. Description The bridge consists of two parallel arches with a free span of and an intermediate deck. The arches rise to a total of with a span-rise ratio of 7:5, and attach to the deck with two connected longitudinal beams. The arches have a triangular cross-section, ...

Cala Galdana
Cala Galdana (Galdana cove) is a coastal resort in Menorca, 9 km south of Ferreries Ferreries is a municipality on the island of Menorca, in the Spanish autonomous community of the Balearic Islands. Its name is derived from the Catalan word ''ferrer'' (" blacksmith"), which in turn, comes from Latin word ''ferrum''. At an eleva .... The cove was largely undeveloped until the 1960s.The Rough Guide to Mallorca & Menorca 0241276500 Rough Guides 2016 - "The bustling resort of CALA GALDANA, 9km south of Ferreries, occupies what was once a much loved beauty spot, its clutter of high rises and low rises disfiguring – at least in part – a once beautiful cove framed by wooded, limestone cliffs."

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.

Menorca
Menorca or Minorca (from la, Insula Minor, , smaller island, later ''Minorica'') is one of the Balearic Islands located in the Mediterranean Sea belonging to Spain. Its name derives from its size, contrasting it with nearby Majorca. Its capital is Mahón ( ca, Maó), situated on the island's eastern end, although Menorca is not a province and forms a political union with the other islands in the archipelago. Ciutadella and Mahon are the main ports and largest towns. The port of Mahon is the second biggest natural port in the world. Menorca has a population of approximately 93,397 (at 1 January 2019). It is located 39°47' to 40°00'N, 3°52' to 4°24'E. Its highest point, called El Toro (from Catalan "''turó''" meaning ''hill''), is above sea level. History The island is known for its collection of megalithic stone monuments: ''navetes'', ''taules'' and '' talaiots'', which indicate very early prehistoric human activity. Some of the earliest culture on Menorca w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both aluminium and copper, having a biological cleanability comparable to glass ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low ultimate tensile strength, tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, Prestressed_concrete#Post-tensioned_concrete, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist Tension (physics), tensile Stress (mechanics), stresses in particular regions of the concrete that might cause unacceptable frac ...

Settlement (structural)
Settlement in a structure refers to the distortion or disruption of parts of a building due to * unequal compression of its foundations; * shrinkage, such as that which occurs in timber-framed buildings as the frame adjusts its moisture content; or * undue loads being applied to the building after its initial construction. Settlement should not be confused with subsidence which results from the load-bearing ground upon which a building sits reducing in level, for instance in areas of mine workings where shafts collapse underground. Some settlement is quite normal after construction has been completed, but unequal or differential settlement may cause significant problems for buildings. Traditional green oak-framed buildings are designed to settle with time as the oak seasons and warps, lime mortar rather than Portland cement is used for its elastic properties and glazing will often employ small leaded lights which can accept movement more readily than larger panes.

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments ( torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary ...
