There are many types of bridges that have been built around the world and suspension bridges remain to be regarded highly when it comes to aesthetic appeal. Disadvantages: Short, not good in earthquakes, and they need multiple supports. The Advantages of Suspension Bridges. Beam Bridges Are Limited By Their Length Since the supports for a beam bridge are typically very far apart, it can be difficult for the bridge to maintain its structural integrity over the long haul. In 1940, high winds caused the Tacoma Narrows bridge, near Seattle, Washington, to collapse. read more. Advantages & Disadvantages of Post & Beam Construction By Patrick Stothers Kwak Hunker may earn compensation through affiliate links in this story. Cost (as always) is the disadvantage. What is Box Girder, Advantages and Disadvantages By Saad Iqbal. If that outcome is not possible, then there is a significant risk of collapse that must be taken under consideration. The weight of the beam pushes straight down on the piers. Advantages . Efficient use of concrete and steel reinforcement or of steel materials if steel structure. Introduction to Continuous Bridges: Continuous bridges are more economical but lack simplicity in the design procedure. Suspension bridges can have very long spans, giving clear area beneath (usually over water so fewer navigation hazards) but take a long time to construct and are very sensitive to corrosion i.e. This doesn't mean beam bridges aren't used to cross great distances it only means that there … The various advantages and disadvantages of T-beam are as following: Advantages: 1. Cannot be loaded in the X-X direction, as the section offer very little structural capacity compared to Y-Y direction. You have named these 3 types of bridge in ascending order of cost.
