    Stressed Ribbon Bridge :

    In a very simple way, I am discussing stress Ribbon Bridge. Have a look!

    Meaning of stressed Ribbon Bridge :

    • Stress simply related to tension and hence stressed Ribbon Bridge is tension structure
    • Suspension cables are present in stressed Ribbon Bridge.
    •  Due to ribbon stiffness gives to the structure.

    Examples of stress Ribbon Bridge :

    here I am discussing actual examples of stressed Ribbon Bridge, they are as follows;

    • Lake Hodges Pedestrian Bridge
    • Leonel Viera Bridge
    • Phyllis J. Tilley Memorial Bridge
    • Rogue river pedestrian Bridge
    • Terwilliger Park foot Bridge

    When the base of the object is inaccessible we use an indirect method of surveying.

    A tachometer is used to measure the distance between the two points with the use of an analytical lens. There are two methods

    1. Stadia method: In this method diaphragm of the tachometer are provided with two stadia hair .the difference between staff intercept gives stadia reading.
    2. Tangential Method: in this method, the tachometer is not provided with stadia hairs, the reading is taken by single horizontal hair.

    D=(f/L)S + (f + d)

    D=horizontal distance between tachometer and stadia rod.

    f/L = multiplying constant

    S= Staff Intercept

    Elevation formula:

    v = KSsin(2©)/2 + Ccos(2©)

    © = Theta= Angle of elevation or depression.

    K & C = Tachometric Constant

    substance method and tangential method is also used to find the elevation between two points.

    While GPS is a global navigation satellite system that gives us time, velocity, location, etc,. The main objective is the accuracy in Position on the earth.GPS works through a technique called trilateration, which collects information to output the information.

    1. Closer bricks: the brick is cut in such a way that one portion is kept remains with the break and used another part for closing the gap.
    2. Queen closer: the brakes are cut along the length for making two equal parts longitudinally called as Queen closer width of Queen closer brick is half of the original brick called as half Queen closer.
    3. King closer: the brick is cut in such a technique that one end of brick width is half of the width of the original brick.
    4. Bevelled closer: in this break, the stretcher face is bevelled in such a way that at one end half-width and on another end, full width is maintained.
    5. Mitred closer: in this break, the one and it is cut in a mitred manner. That is a 45 to 60-degree angle with length. It is shown in the above diagram.
    6. BAT: if along the length, the brick is cut called as a bat.
    7. Half Bat: along the length, bricks are cut into two equal part.
    8. Three-quarter bat: length equal to 3 quarter of the full-length brick.
    9. Bevelled Bat: width is bevelled. As shown in fig.

In other words, the material has the ability to deform under compressive stress. And here ductility is the ability of the solid material to deform under tensile stress. Practically, a ductile material is a material that can easily be stretched into a wire when pulled.

    The thickness of the concrete cover measure is usually part of the concrete quality control in modern construction so as to ensure that the thickness of the concrete cover in conformity with the specifications. The process of measuring the thickness of the concrete cover in structures was noted by the beginning of the corrosion, as the lack of concrete cover thickness increased the corrosion rate for corrosion as a result of chlorides or carbonation, where it expedited the propagation inside the concrete, causing the speed of steel corrosion as well as the lack of cover helps the propagation of moisture and oxygen, which are form the main basis for the corrosion process.

Hi, With regards to your article (link: https://test.theconstructor.org/geotechnical/soil-maximum-dry-density-optimum-moisture-content/18426/), what is the reference in standards. I done check with BS 1377:1990 Part 4 ; but there is no statement saying the range of optimum moisture content for different soil type. If your author ...

    The optimum moisture content of soil actually varies and a standard value for silt, clay, and sand is not strictly mentioned in most of the codes. The values mentioned in the article were based on the general laboratory test values based on Indian Standard Tests and Indian soil conditions. If my knoRead more

    The optimum moisture content of soil actually varies and a standard value for silt, clay, and sand is not strictly mentioned in most of the codes. The values mentioned in the article were based on the general laboratory test values based on Indian Standard Tests and Indian soil conditions.

    If my knowledge is right, we do mention the average moisture content value within a range.

    Thanks for your feedback and query
