CRITICAL ANALYSIS OF THE LUPU BRIDGE IN SHANGHAI
L J H Ellis
Dept. Civil & Architectural Engineering, University of Bath
Abstract: This article provides a critical analysis of The Lupu Bridge in Shanghai. The bridge is currently the world’s longest spanning steel arch bridge with a span of 550m. The analysis of this report includes sections on aesthetics, loading, structural analysis and construction. The Lupu Bridge is a steel through-tied box-girder arch bridge and it is also the only steel arch bridge in the world to be completely welded. Keywords: Lupu Bridge, Steel, Arch Bridge, Longest Span, Welding.

1 Introduction
The Lupu Bridge is located in Shanghai, China. It is currently the seventh crossing to be constructed over the Huangpu River in the city. The bridge is located in the south of the city with the aim to ease congestion in the quickly developing areas around the southern side of the river and the city centre and also to help with the increasing traffic expected at the 2010 world Expo.
The venue for this is set to be surrounding the river at the location of the bridge, so it will not only be a vital part of the infrastructure for this event, it will also act as a showpiece for Chinese engineering.
The bridge was officially opened in June 2003 at a total cost of $302 Million US. On completion the Lupu
Bridge was the largest spanning arch bridge in the

world with a main span of 550m overtaking the New
River Gorge Bridge in the United States by 32m. This record is set to be broken in 2008 by the under construction Chaotianmen Bridge in China by only 2m.
The total length of the bridge is 3,900m including the approach bridges on either side of the river.
The bridge was originally heavily criticised as it was seen as wasteful by many people in respect to the type of bridge that was actually needed for the project.
Many feel that it is just a show piece for the city and the price tag reflected that

    Each type of design is although, unique in its own way, fulfills the desired goal that the Truss Brides are made for. The purpose of this experiment is to research various bridges and build a similar one that gave the students the highest inspiration. For one case in particular, the bridge design was in-spired by the Pratt Bridge and almost every height, width, and length met the requirements ex-cept for the length on the bottom part of the bridge, it exceeded the maximum height that was asked. Moreover the bridge held a total of 20 pounds before one of the top sticks snapped. Alt-hough it performed a decent job, the bridge could have held more weight if there were more di-agonals to provide more support so the bridge wouldn't break. Furthermore, this bridge fulfilled its goal and held a large amount of weight for such a small bridge. These bridges are also very significant for this planet because it is very resourceful and effective, as well as…

    The materials that were used to construct this bridge consisted of prestressed concrete, steel casings, prestressed steel, reinforcing steel wire strands and polyethylene. It was built on each side of the land and was eventually connected together in the middle. It was constructed by using a formtraveller (a travelling formwork) and setting up the formwork before positioning and tensioning the cables. They then proceeded to place the reinforcement cement and pouring on the concrete. This was made in a cycle with each cycle being used to make…

    In conclusion the I-35W Bridge’s design had some flaws which led to the collapse of it in August 1, 2007 and in this paper we spoke about the structural form of the I-35W bridge, some circumstances that led to the collapse, why the bridge fell and some post-effects of the collapse. If the construction company have calculated that the bridge was already in enough stress and not placed the construction material above the design flaws, which were the gusset plates, the collapse would have been…

    They are built using cantilevers; horizontal structures that are only supported on the ends. These bridges are anchored securely on one side, in order to hold up the necessary weight on the opposite side, which is freestanding. Cantilevers must also withstand tension in the upper supports and compression in the lower supports. With proper materials and engineering, cantilever bridges can span over about 1,500 feet.…

    Truss Bridge Design

    As well, we learned about the pros and cons of different types of truss bridges namely the Warren truss, Pratt and Howe trusses, and the Fink truss. Additionally, it was concluded from the research that triangles will experience both tension and compression when a force is applied on them, since the triangle spreads the compression force sideways to the ends of the bridge, therefore allowing support for a maximized load. Equilateral triangles are commonly used as they minimize forces to tension and compression. From the bridge research, it was concluded that the first types of bridges such as the Warren truss and the Pratt and Howe trusses are not optimized to keep a load; this crates the decision to construct a Fink bridge. The reason for this choice is that the Fink design is with a large triangle, with numerous smaller triangles inside the large triangle for reinforcements, which signifies that the Fink design would be strong, especially if the load is applied to the middle, due to the strengths of triangles. Additionally, to further strengthen the bridge for a centered load, the bridge should have a high depth at the middle. Also, in order to ensure that the bridge spans at least 90 cm, and to add strength, it was decided that a Triple Fink bridge be constructed. Due to the triangles in the design, this is even further reinforced by the overall triangular…

    The towers of the bridge are built of limestone, granite, and Rosendale cement. The blocks used on the bridge were built in Manie and shipped to New York by schooner. Once the construction of the suspension/cable-stay hybrid bridge was complete in 1883, it had a total length of 5,989 feet and with a width of 85 feet. It was 41m tall and weighed a whopping 14,680 tons. On its first day, a total of 1,800 cars and 150,300 people crossed what was then the only way to get to the other side.…

    A truss bridge is a bridge whose load-bearing super structure is composed of a truss, a structure of connected elements forming triangular units. The connected elements are typically straight. The truss bridge is different because it uses triangles, its way brought about in the 19th and 20th century. in paragraph citation (author, year) ) J.B. Calvevt Created July 19 2000.…

    Most suspension bridge roadways were lighter because light structure would put less stress on the cables. However, this light structure would not be a good support for the bridge since it can sway in the wind. Therefore, Roebling decided to use steel wires to support roadways which is why the bridge was considered not only a suspension bridge, but also a hybrid cable-stayed bridge. Just like any suspension bridge, Brookyn Bridge has anchor, approaches, towers, deck, cable, hanger and foundations. The marvel stone towers of the bridge are made of mostly granite with a mixture of limestone and Rosendale cement. These towers are considered gothic towers due to its similar visual to Gothic architecture from medieval period. Additionally, these two towers have arches that can be compared to a Roman architecture “ The Arch of Constantine” (History,…

    At the time of this project there was not much know about the dynamic factors about as Suspensions Bridge so the management and planning for this project was appropriate. It had always been taken for granted in bridge building that static (vertical) load and mass of large structures were enough to protect them. The Planners took unknowing risks when the open girders in the bridge’s sides were substituted with flat, solid girders that would catch the wind and make the bridge sway from side to side. One distinguishing feature that led to its “sway to destruction” was the bridge’s small width-to-length ratio; the bridge was incredibly narrow for its length also its topographic location made it very prone to high winds. These risks were never taken into consideration at the time. Project managers did not take them sufficiently into consideration since at the time was not much known about the dynamic factors.…

    The "Truss Bridge" is similar to a beam bridge except much stronger. These bridges use a pattern of geometrical shapes (triangles) called trusses. These trusses are very rigid (they don't move when pushed) and, thus, make the bridge very STONG! Because of their strength, truss bridges are often used for railway bridges as they must be able to support the great mass and the vibrations of the trains.…
