According to the concept of Limit State Design as per IS 456: 2000, the probability of failure of a structure is __________.

A column of size $$450\,mm \times 600\,mm$$ has unsupported length of $$3.0$$ $$m$$ and is braced against side sway in both directions. According to $$IS$$ $$456: 2000,$$ the minimum eccentricities (in $$mm$$) with respect to major and minor principal axes are:

In a pre-stressed concrete beam section shown in the figure, the net loss is $$10\% $$ and the final prestressing force applied at $$X$$ is $$750$$ $$kN.$$ The initial fiber stresses (in $$N/m{m^2}$$ ) at the top and bottom of the beam were:

Prying forces are
