The Danyang-Kunshan bridge in China is considered the world’s longest bridge with a length of 164.8 kilometers. The bridge connects two very large cities in China, Shanghai and Nanging. The Danyang-Kushan bridge also connects Danyang and Kunshan in the section of the Beijing-Shanghai High-Speed Railway that connects the Beijing West Station and Shanghai Hongqiao Station. During its construction, it took almost 10,000 construction workers to complete this engineering feat, which made the completion of the construction possible in only 4 years. One notable part of the Danyang-Kunshan bridge is its 9km long section that spans over Yangcheng Lake. This particular section required at least 2,000 pillars to support it. This massive structure required 450,000 tons of structural steel, making it a very sturdy structure. The sturdiness of the bridge allows it to withstand massive natural disasters such as typhoons and earthquakes of magnitudes reaching 8 on the Richter scale. Furthermore, the bridge is also able to withstand the impacts from naval vessels that weigh up to 300,000 tons. Furthermore, since the bridge had to function for a high-speed train, the design speed was an important factor to take into consideration. Depending on the type of train, the maximum speed of the railways varies from 250km/h to 350km/h. However, for the Danyang-Kushan bridge, the railway line of the bridge had to be designed for an operating speed of 350km/h and a maximum speed of 380 km/h due to its busy hours.
In the dictionary, Camber is defined as "a raised surface or a member raised upward." In other words, it means ‘to bend higher than the original/target shape’.

With rapid development of new technologies and materials, there has been major changes in how bridges are designed. In the past, engineers did not have the tools or software to provide accurate models or detailed analysis of bridges. However, with today’s advancement in technology, new advanced construction methods, materials, tools, and software are now available for bridge engineers.

A girder bridge is one of the most common types of bridge design. Prestressing a composite girder in the negative moment region increases its stiffness by preventing cracking of concrete under service loads. In this webinar, we share the design practices of girder span bridges in Sarawak and show which functions of midas Civil can be utilized for the effective modeling of this type of structure.
