Flooding to the Correction In the last post, I assured that I will write on the measures which we took, conforming the enhance protection of the bridges and embankments against damages caused by scour. After a devastating rainy season which happened during the project implementation, we were convinced on the additional requirements of the protection measures which were not included in the original designs. ...

I caught this video from FB post..........This video shows the importance of the correctly design HYDRAULIC JUMP at the spill.I can remember the effort of my Hydraulic Professor who took great effort to teach us the phenomena during my undergraduate studies. The hydraulic jump is designed to dissipate the energy of the water flow, so that it flows in safe speeds inthe downstream.

Cracks in Prestress concrete Beams I came across this problem last year. Although the issue has been solved, still I think we can share our views on this.The problem occurred on 19m long pre tensioned PSC beam. The cracks, in the range of 0.2 mm – 0.5 mm, were noticed on the top flanges of the 19 m beams and near the two lifting positions ...

Cracks in 19m long Prestress concrete Beams I came across this problem few months ago. Although the issue has been solved, still I think we can share our views on this.The problem occurred on 19m long pre tensioned PSC beam. The cracks, in the range of 0.2 mm – 0.5 mm, were noticed on the top flanges of the 19 m beams and near the two lifting ...

Modeling of Slab Column junction in FEM In structural engineering, the Flat Slab is identified as a slab which is supported generally without beams by columns with or without column heads. However, I have understood that Flat Slab designs are not quite popular in Sri Lanka, may be owing to its complexity in design, detail and construction. But things what I am going to discuss here are ...

Is excess cover for R.F good? Many times, during my site inspections, I have found fault with the Contractors for providing an inadequate cover for the reinforcements in R.C structures. Obviously inadequate cover for the R.F has to be rectified immediately as less cover causes the larger crack widths in concrete and thereby it exposes the reinforcement to surrounding environment to get corroded. This is ...

I have been very busy since last August,2010 owing to my academic work, job and family commitments. Although work loadings in every fronts are mounting up, I thought time is right for recommence this blog which I really enjoyed in past. It simply keeps alive my appetite to learn.Unlike in previous writings, this time I am thinking of writing more ...

Last time I wrote that Civil Engineering is a half science plus half art. The artist feels something intangiable where he will convey that feeling to rest of us through his Art.Then how could Engineer become a half artist?..confused??Engineer feels the answer (which is an art) and then use his science to achive that answer ...that is an art..see the ...

During the time of my undergraduate, one of my professor took a great effort to teach us the difference between a mathematician and an engineer. To his credit, he almost did it in a 100%Mathematics is the paramount in engineering. But Engineering is not all about mathematics.The photos which received from a email gave me better way of presenting the ...

Nothing is softer or more flexible than water, yet nothing can resist it. - Lao TzuWater is an important entity in our life.Still most of you may not aware that Civil engineers play a significant role when it comes to providing the drinkable water (palatable) to your tap. Water treatment is a highly developed area where so many civil engineers ...

Creativity at its best... Today I came across a good picture which you can see below, where it gives a different perspective to the subject matter of 'Women'. Although I' m not intended to find the validity of above, my simple intention is to appreciate the creativity an

Mix Design of a Man I think character or the personality of a person is a mixture of Attitude, Knowledge, Skills and Luck. In my way of thinking, the correct mixture of above should always make a strong character and it will make a person who withstands to various types of problems which he comes

The Tallest Bridge There are so many Guinness records for the tallest entities which may fall in to the categories such as tallest man,tallest woman,tallest building etc.So,I thought it would be appropriate to discuss the details about the world tallest bridge through this blog.The world highest Bridge is 'Mill

Can you sing a Bridge..... It would be hard to find a person who has not gone across a bridge during his lifetime. But, have any of among you taken the trouble to look at the underneath of a bridge?, which helped you to cross over the river. Surely,

what's happening in UOM? This year (2010),the field selections of University of Moratuwa (UOM), SL, have depicted a different trend from its past consistent behavioral pattern. Even though, when considering the whole picture, it cannot be catogor

Women as Concrete Machines.. While we were having a beer, one of my Zambian friend, Earnest told me that their women are concrete machines (wow!!! Sure SL contractors think of importing few of them )While thinking of that good idea, i thought to write my n

Deeper you go..Larger the cost.... This time I thought to write something reference to the foundation design in bridges. Typically two types of foundations can see in Sri Lanka. i.e1. Spread Footing2. Pile FoundationI thought to discuss why pile design is defer in Bridges compar

I thought to start my first blog with a simple but very useful information to civil engineers and technical officers.I have seen very senior engineers going through their handbooks when they were been asked to calculate the weight of a particular length of a R/F bars. But if you can memorize a simple data, it is totally unnecessary to refer ...
