When Professor Liang Sicheng of Tsinghua University rediscovered the bridge on a field exploration of ancient architecture in Hebei province, he made detailed measurements and published a report and drawing,[10] after which the bridge became world-famous. were also new. For a little less than 1500 years old, this bridge is absolutely amazing and really displays true Chinese innovation. The fact it can withstand 8 tons is incredible! Bridges of that design stretch over expressways around the world. The bridge pictured This research aims to introduce a new techniqueoff-site and self-form segmental concrete masonry arches fabrication, without the need of construction formwork or centering. Its amazing how it is still standing today, despite the fact that it was built around 600A.D. The bridge has a span of 123 feet. - Any part supported from arch below may have spandrels that are closed or open. is seen as one of the great achievements of early Chinese engineering, -The [11] In 1996, the Chinese authorities nominated it for inclusion in the World Heritage List as having "a very important place in the world bridge building history".[12]. James M. Hargett, On the Road in Twelfth Century China: The Travel Diaries of Fan Chengda (1126-1193) (Stuttgart: Steiner Verlag Wiesbaden, 1989).

This innovation, which occurred between the end of the sixth century and beginning of the seventh century, repudiated conventional wisdom that a semicircular arch was necessary to transfer the weight of a bridge downwards to where the arch tangentially meets the pier. The arch length to span ratio is 1.1, less than the arch-to-span ratio of 1.57 of a semicircle arch bridge by 43%, thus the saving in material is about 40%, making the bridge lighter in weight. The bridge had a span of 123 feet. This solid wall at right angles to the span was set close behind the spring of the arch on both sides of the watercourse, reinforcing the abutment with its relatively deeper foundations. Other given data are: Span, S = 72 in. The ship-like piers easily cut the rapid current of the river. Many modern bridges, made of steel or reinforced concrete, often bear some of their load by tension within their structure. Only the ornamental railings have been replaced every few hundred years. Very interesting article! This made the bridges broader and flatter than semicircular arches could. Mortar was not used in the arch and foundations, and the masonry foundations were often set on wood piles. It was a really cool article to read!

In the spring, this river is periodically subjected to large flood flows laden with flow-ice and/or forest debris . Thanks so much for teaching me these things! And since his An Ji Bridge has survived most of its predecessors and contemporaries, he is now recognized as the builder of the oldest great segmental arch bridge in the world But he has an even greater claim to fame since his An Ji Bridge is also recognized as one of the shallowest or boldest segmental stone arches ever constructed. The deck of the Fremont Bridge goes through the arch, the central span is suspended from and ties the arch, while the side spans of the deck are supported. - The Made in 600 AD?? China's oldest bridge still standing, Zhaozhou Bridge has spanned the Jiao River (Jio H) for 1400 years. He found that this bridge can withstand as much as eight tons of weight!

Therefore, they did not rely on their own heaviness for stability, instead fitting together exactly to shape a thin shell, which passed the load on to the abutments. These spectacular structures couldnt be build without the mind of engineers. Derk Bodde, Chinese Thought, Society, and Science: The Intellectual and Social Background of Science and Technology in Pre-Modern China (Honolulu: University of Hawaii Press, 1991). A single-hinged bridge has a hinge at the crown of the arch, a two-hinged bridge has hinges at both springing points and a three-hinged bridge has hinged in all three locations.

I have always been fascinated with art and architecture of our increasingly diverse and globalized world, and this is quite an architectural marvel, rivaling some of Wright, Pei and Gehry. The Anji bridge influenced the design of later Chinese bridge structures, such as the similar Yongtong Bridge near Zhaoxian in Hebei. . Later similar bridges were built with flat segment arches and open spandrels. It is a single segmental stone arch, composed of 28 individual arches bonded transversely, 37.02m in span and rising 7.23m above the chord line. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a tied-arch bridge. As apparently recognized by Joseph Needham, any great work of engineering and architecture owes its existence and appearance to the evolution and performance of successful progenitors And evidence of some of these An Ji Bridge progenitors have been found by Huan Chang Tang, the co-author of this paper In his book on the History of Chinese Science and TechnologyBridges (2), Tang provides photographs of a number of stone panel carvings from the Han Dynasty (202 B C to 220 A.D.) depicting the use of short-span segmental arches being used as roadway bridges for small stream and canal crossings (Figure 3 1) However, unlike the An Ji Bridge, which has a shallow rise of only 19 percent of the span length and a relatively straight roadway, these early segmental bridges had little or no approach embankments, arch rises of nearly 25 percent of their span lengths, and roadways that paralleled arch curvatures Consequently, to negotiate such high rise segmental arch bridges, special practices had to be devised to help horse-drawn carriages cross over the hump of such bridges And the carved panels from the Han Dynasty illustrate how this was done, Some of these carved panels show a group of three laborers stationed at each end of arch type bridges It appears that the laborers are handling ropes attached to horse-drawn carriages crossing the bridges Those at the forward end of a bridge help the horses by pulling its carriage to the bridge's apex, while those at the rear are waiting to slow a carriage's descent by pulling on it from behind Some of the panels depict arch bridges with intermediate supports while other panels show arch bridges without such supports So it is clear that some of these panels are depicting single-span segmental arch bridges Since many carriages with multiple horse teams are also depicted on these panels, and groups of laborers with ropes are shown stationed at each end of each of these bridges, it appears clear that in Ancient China methods had been developed to expedite the movement of vehicular traffic across waterways on segmental arch bridges before the beginning of the last millennium. ." Helped people to record information and share information . [6], Among the most remarkable achievements of Chinese bridge buildingindeed an advancement unrivaled in the worldwas the creation of this segmental arch bridge of wholly stone construction. The innovative construction method in the current study encompasses two construction materials forms the self-form masonry arches, wedge-shape plain concrete voussoirs, and carbon fiber-reinforced polymer (CFRP . This type of bridge is usually made with three spans: the outer two spans are anchored on the shore, while the third is projected out over the channel and supported by cantilever beams on only one side. Also, it sounds like the open-spandrels are what really gives this bridge its namesake.

The magnitude of the earthquakes that occurred between 1956 and 2002 varied from about 4 .70 to a maximum of about 7. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio (1345) combined sound engineering (span-to-rise ratio of over 5.3 to 1) with aesthetical appeal. Safe Crossing is aptly named! Second, when the bridge is submerged during a flood, they allow water to pass through, thereby reducing the forces on the structure of the bridge. The bridge is also commonly known as the Zhaozhou Bridge, or in Chinese, (Zho zhu qio). They let through additional floodwaters and also (203 mm) Rise, r = 6 in. Wow, thats incredible!
