Question

Consider the following statements:
The shear resistance of structural concrete members may be improved by:

Which of these statements is/are correct?

• A. 1 only
• B. 1 and 2 only
• C. 2 and 3 only
• D. 1,2 and 3

Answer 1

The correct option is D 1,2 and 3

In general there are three ways of improving the shear resistance of structural concrete members by prestressing techniques viz.
(i) Horizontal or axial prestressing
(ii) Vertical or transverse prestressing
(iii) Prestressing by inclined or sloping cables
However, vertical prestressing is not cables being short, the loss of prestress due to anchorage slip is excessively large.
