In working stress method, modular ratio = 280/(3*σcbc) 280/(2*σcbc) 260/(3*σcbc) 280/(3*σcbc^2)2. Assumed depth of rectangular stress block as per IS456 for working stress method = 0.43d 0.42d 0.40d 0.66d3. For limit state of collapse, partial factors used are 1.2 for steel and 1.5 for concrete 1.15 for steel and 1.5 for concrete 1.1 for steel and 1.44 for concrete 1.3 for steel and 1.8 for concrete none of above4. The value of short-term moduli for Concrete, Ec = 5000 x sqrt(σck) 5700 x sqrt(σck) 5100 x sqrt(σck) none of above5. The modular ratio for a section, increase with increase in strength of concrete decrease with increase in strength of concrete always remains the same decrease with increase in yield strength of steel6. To calculate the deflection under live loads, which of the following values has to be used? Long-term modulus of concrete Short-term modulus of concrete7. Compressive stress in concrete for Limit state design without partial safety factor = 0.67 σck 0.60 σck 0.66 σck 0.65 σck8. Limiting value of a section with Fe 500 grade steel = 0.133 σck b (d)^2 0.138 σck b (d)^2 0.148 σck b (d)^2 none of above9. As per IS456, the limiting value of the depth of neutral axis, remains same with change in yield stress increases with increase in yield stress decreases with increase in yield stress none of above10. As per IS456, the limiting value of the depth of neutral axis, for Fe 415 grade steel = 0.53 d 0.48 d 0.46 d none of above11. The depth of beam to be considered to calculate nominal shear stress should be Gross depth of section Effective depth of section Depth of concrete under tension None of aboveBe sure to click Submit Quiz to see your results!Please enter your mail id to get the correct answers on your mail.
