In a reinforced concrete section, the stress at the extreme fibre in compression is $$5.80$$ $$MPa.$$ The depth of neutral axis in the section is $$58$$ $$mm$$ and the grade of concrete is $$M25.$$ Assuming linear elastic behavior of the concrete, the effective curvature of the section (in per $$mm$$) is

For a beam of cross-section, width $$= 230$$ $$mm$$ and effective depth $$= 500$$ $$mm,$$ the number of rebars of $$12$$ $$mm$$ diameter required to satisfy minimum tension reinforcement requirement specified by $$IS:$$ $$456-2000$$ (assuming grade of steel reinforcement as $$Fe500$$) is _______________

A steel section is subjected to a combination of shear and bending actions. The applied shear force is $$V$$ and the shear capacity of the section is $${V_s}.$$ For such a section, high shear force (as per $$IS:800$$-$$2007$$) is defined as

The tension and shear force (both in $$kN$$) in each bolt of the joint, as shown below, respectively are
