In this post we will try to examine various design and construction considerations for wide span roofs. Read More

In this post we will discuss various aspects when designing and analyzing Reinforced Concrete (RC) moment frames and behavior of structural members. Read More

In this post we will look at seismic strengthening methods of concrete buildings. Read More

The three main types of tunneling are Let’s take a look at each briefly… Cut and cover method: This is a frequently used method when the required tunnel excavation is not very deep (i.e. up to around 80 feet or so). The method involves excavating a trench in the ground, and not boring the tunnel underground. At what stage this excavation is performed with respect to the tunnel construction makes a difference. Because of this, cut and cover method can be grouped into two as, bottom up method and top down method. The bottom-up method is the straightforward one. First the retaining walls are inserted into the ground, that will […] Read More

Of course when we talk about structures, the first thing that comes to our minds is the buildings, as we live in them, and we see all sorts of them around. By buildings we mean all kind of buildings that enclose an area from outside and separates it with the outside… such as residences, offices, high rises, warehouses, factory buildings, sports halls, malls… Only after the architectural design is complete, which determines how will the building look, how big or small, what functions it will perform where, how will the interior spaces be allocated, how many levels it will be, only after that, the engineering design comes into play. The […] Read More

Railroads, in many instances can provide a more efficient way of transportation. For example, in developed countries like Europe or Japan, people can access to almost anywhere, including to or close to even small towns, with railroads and the big cities have extensive metro networks, which are also considered as railroads, from civil engineering point of view. The benefits of railroad vs car transportation are virtually limitless, in terms of economy, environment, speed, efficient use of land and more. The geometric design concept of railroads, in terms of horizontal and vertical alignment is in principle similar in to road design, with necessary differences and lower tolerances. For example, the cross […] Read More

The third airport of Istanbul, the largest city of Turkey with a population of 18 million, is set top open soon, on October 29th, 2018. The moving from the current primary Atatürk Airport to the new airport has started this week. The current Atatürk Airport is home to 70 Million Passengers a year, which is still considered one of the largest airports in the world, and it is the first time in history that an airport of this size will move. The new airport is at a distance of 45 km from the current one, still on the European side of Istanbul.The move is such a big one that outside […] Read More
