The Types of Bridges

the main types of bridges with details

Bridges are essential when it comes to passing all kind of gaps/spans for civil engineers so the types of bridges as well. When we have discussed any kind and any types of bridges there can be complications especially with the less experienced civil engineers, even I had confusions in the past, moreover if English is not your native language it can be more confusing. These days I am preparing some documentation about my professional engineering career and I have found these drawings. They are showing clearly the types of the bridges in the simplest way.

The drawing above shows the 4 main types of bridges, even LOADs, SUPPORT and COMPRESSION Points.

The 4 Main Types of Bridges:

  1. Beam Bridges: This type of bridges are mostly chosen also cost effective based on the performance. Can be built in different spans based on the design. Especially chosen for the ease of construction.
  2. Truss Bridges: You will remember them from the western movies, the railroad bridges … 🙂 But be careful about the maintenance part.
  3.  Arch Bridges: Visually my favourite but the foundations need to be firm. Commonly used in the old world by the Roman Empire especially for water transportation, I have seen marvellous stone arch bridges.
  4. Suspension Bridges: If you have to pass long spans this is the type you are going to use but not cost friendly as beam bridges.

The drawing below shows more detailed bridges like floating bridges, bascule bridges and etc.

My main purpose is to make a small base for engineers looking for types of the bridges, at least having an idea about them.

We can use more detailed drawings and bridges but my aim is to keep the list as simple and less confusing as it can be.

The List of Bridges

Which One Is Better; 4 Way Stop Vs Roundabout

this is a global question; Which One Is Better; 4 Way Stop Vs Roundabout
I can write lots of thing through the experiments and researches to determine which one is better but there is a fact that Americans are fan of 4 way stop and English are definitely on roundabout side. but lets watch the Mythbusters episode trying to find out the answer… “Which One Is Better; 4 Way Stop Vs Roundabout ”

Personally I still feel more relax with 4 way stops than roundabouts which the NY Times article “Roundabouts: Efficient or Annoying?” which can be read at here shows that some are thinking like me.

Last, for low density roads it seems like roundabouts are better (of course with the countries people tend to obey the traffic rules) however depending on the actual traffic flows a 4 way intersection with intelligent traffic lights could be quicker overall for medium or high density roads.

How to Build Speed Humps

Speed Hump construction

I should admit that I am a bit obsessed with speed humps, especially as a civil engineer how to build speed humps which I see a lot of speed humps which are just built without any projection nor calculation; some too short, some too high and some with so short intervals that I saw three speed humps built side by side which you feel you are on the off road and etc.; But in total making me annoying.

So I tried to gather various sources together and prepare a reference; here is how to build speed humps by specifications and standards; Read More

Engineering in the Ancient World

Engineering in the Ancient World Book Cover1Lets talk about the ancient world and especially “Engineering in the Ancient World” through a book named as same as the topic which I have read recently which have enlightened me about some topics especially hydraulic engineering.

Especially the topic “Water supplies and engineering” was my favorite as it answered many questions in my mind about engineering in ancient times. For example the explanation of how they bored water tunnels from different locations and connecting each nearly without any Read More
