Which is the Indian code for post tensioning?
TR 43 is the Indian code used for post-tensioning
What is difference between pre tension and post tension precast girders of bridge?
A simple explanation: PRE tensioned- cables are tensioned, and the concrete is cast around it. The tensioning is done BEFORE casting the concrete (PRE = before). POST tensioned- cables are placed inside of ducts or are greased to prevent bonding to the concrete, the concrete is cast around the cables, and then the cables are tensioned after the concrete has reached a desired strength. The tensioning is done AFTER the concrete is cast (POST = after).
What does a Threshold Inspector do?
A threshold inspector is a certified building inspector who works for a consulting / engineering firm. If a building exceeds either a height, square footage, or occupancy load, the client usually funding the project is required by law to hire a threshold inspector. In addition to performing structural inspections, a threshold inspector will oversee certain activities during building such as pouring concrete and post tensioning. Threshold inspectors can be considered a form of quality control seeing that the are hired by the developers and not the general contractor, therefore not having to answer to the GC.
How do you calculate the vol of steel to a given vol of concrete?

What does the Post Tensioning Institute do?
The Post Tensioning Institute is a non-profit organization that specializes in prestressed concrete design and construction. The institution is recognized worldwide for it's authority on post-tensioning.
What is the definition of post tensioned concrete?
Post tensioning is the prestressing of a concrete member by tensioning the reinforcing tendons after the concrete has set
How do you calculate percent elongation in materials?
To calculate percent elongation with an equation: [(final length - initial length) / initial length] x 100 = percent elongation On a graph - To calculate percent elongation, draw a line to the x-axis from the point of fracture parallel to the straight line part of the graph. The extension at this point is then divided by the gauge length.
How falsework is affected when post tensioning of concrete takes place?
Falsework is usually designed to temporarily support the weight of concrete during curing. When post-tensioning of concrete takes place, the falsework may experience additional loads and stresses due to the forces induced by the post-tensioning tendons. It's important to ensure that the falsework can safely support these additional loads to prevent any failure or collapse.
How do you calculate elongation and area reduction?
Intial volume = final volume from this approach if you know any one of them % reduction in area or % elangation. you can calculate other
How many cycles of elongation are required to produce a protein with 100 amino acids?
One cycle of elongation adds one amino acid to the growing polypeptide chain. Therefore, to produce a protein with 100 amino acids, 99 cycles of elongation are required, as the initial methionine is not incorporated through elongation but rather at the initiation step of protein synthesis.
How do you find out elongation on a graph?
To find elongation on a graph, you need to identify the points where the graph reaches its maximum and minimum values within a specific interval. Elongation is typically represented as the difference between these two extreme points. You can calculate this by measuring the vertical distance between the highest peak and the lowest trough on the graph. Additionally, if the graph represents a periodic function, the elongation can be assessed by examining the amplitude of the oscillations.

What is the relationship between engineering strain and percent elongation?
strain is percent elongation/100; for example a strain of 0.02 is 2% elongation. Often we refer to elongation at failure; for example if a material fails at 10% elongation its strain is 0.10

Does the elongation of the cells in the region of elongation increase the root length?
no
