Bridge 01 history and culture
Origin and development of the bridge
Bridge, the same ancient man-made miracle as the building building, dates back to the poems of daya da ming, the poem “build a ship, without light”, which depicts the beauty of the ship as a floating bridge, and of the sea as a way of meeting its neighbours. The link between the bridge and the beam has been closely linked, as explained in the psalms and shin dong han-shin, reflecting the early exploration of the wood structure of the bridge and its water function. The close link between the bridge and the beam is further explained by shin dong han-hyun, who points out that the bridge is the beam on the water, while the beams are from wood and water, and that the wood structure of the bridge and the functions on the water are implied. As a result, the bridge and beam have been closely linked throughout history, and together they represent a remarkable chapter in human construction。
In ancient times, bridges and beams were not only proximate in form, but corresponded to each other in function and structure. As can be seen from the remains, whether it beams or beams in wooden bridges, stone bridges or building buildings, the early exploration of bridge technology by humans is evident. Similarly, the image of han's bricks and drawings of liang bridge also shows us the structure and form of the ancient liang bridge, which is to build a beam on a pillar and then lay a stone or a plank, forming a solid and practical bridge。
Impact of ancient western bridges
In two river basins, ancient greece and ancient rome, stone-based ancient bridges have shown exploration and achievements similar to those of the present. Not only in my country, but also in our ancient west have a long history of bridge. Arch bridges, with stone as the main building material, are widespread in the two river basins, ancient greece and ancient rome. Despite differences in geography and materials, these ancient bridges have been constructed in a similar way to the existing contemporary ones, demonstrating the common exploration and achievement of bridge technologies by humankind。
The function of bridge 02 combined with aesthetics
Structure and aesthetics of bridges
Bridge, this time- and space-spreading architectural miracle, carries with it feelings and dreams from ancient times to the present. The image of the bridge has changed so much in poets' writings, ranging from the euphoria of the “long bridge bed, no cloud, no cloud, no rainbow?” described by doo-hashi, to the silence of the “nug-song-song-song-song month, man-song-song-song-song frost” . Today, as urban transport becomes more and more busy, the role of bridges in cities has become more prominent, not only as an important symbol of the urban landscape, but also as an important factor in connecting functional urban areas. The shape and functionality of bridges are becoming more demanding, and it seems to be hoped that each bridge will be both beautiful and practical。
However, the functional demand for bridges and the mechanics of the design of aesthetic passage lines are mutually driven and form is derived from structure rather than visual modification. Bridges are shaped by their structure itself, a combination of strength and function, rather than relying solely on visual modifications. Therefore, when looking at the beauty of bridges, we should pay more attention to the intrinsic link between their form and their mechanics. On this basis, this paper will attempt to deepen the understanding of the relationship between the bridge form and the mechanics in terms of the mechanics of the connection。
Case study of prominent bridges
“long bridge bumping, unmong hyolong?” — mechanical content of the hong kong joao bridge. Bridge, this architectural miracle across time and space, not only carries with it the emotions and dreams of people, but also demonstrates the beauty and beauty of engineering. Examples such as the hong kong joo-au bridge and the yogo conset bridge in switzerland, and the chongqing gaeung river bridge illustrate the combination of functional and aesthetic aspects of bridge design and respect for the surrounding environment。
First of all, let us look at yogo cortezte in switzerland, a brilliant structural engineer and bridge designer who designed a footbridge across the viamala canyon in the alps, providing a safe passage for hikers. The bridge tactfully introduced pre-formulated simple beam bridge technology, with the overall suspension, showing a shift in the curve of the beam. At the same time, the aesthetic and functional combination of structure has been perfected through a combination of triangles of steel wood。
Let's look at another example of a bridge, a work designed by sergeant deng for chongqing kaeung bridge. The esoteric bridge of the "y" pyramid displays elegant features in form, scale and colour, fully reflecting the designers' deep understanding of and respect for the environment。
“the bridge is not just a link, but a bond of emotion.” in the design of the bridge, every trade-off and creation by the designer reflects a deep understanding of functions, materials and mechanics, as well as a careful appreciation of the environment, form, scale and human condition. The design of the bridge is not only about functionality, but also about the emotional needs of the people, which is the profound beauty inherent in the structure of the project。
