Top 10 World’s Longest Prestressed Concrete Girder Bridges

midasBridge TeamNovember 19, 2020

Prestressed concrete is a structural material that allows for predetermined engineering stresses to be placed in members to counteract the stresses of loads. It combines the high-strength compressive properties of concrete with the high tensile strength of steel. These prestressed concrete girder bridges are currently used in bridge construction all over the world. Research on materials and superstructures of bridges has shown that prestressed concrete girder bridges have the longest life span and require less maintenance than other bridges. Furthermore, these bridges are increasingly being used due to their aesthetic versatility, strength, quality, and reduced construction time.

 

Design of Girder Span Bridge with PSC Sections

midasBridge TeamApril 20, 2020

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.
