2. Tensile strength of concrete is about: (20-35)% of compressive strength (45-70)% of compressive strength None of the above. Tension controlled section Balanced section Compression-controlled section 4- The reduction factor (0) is equal to 0.9 if the: Es 2 Ety + 0.003 Es S Ety + 0.003 Es Ety 5- The design method which use the factored loads is - Working stress method - Ultimate design Method - None of above 6- If p< Po therefore the section is - Under reinforced - Over reinforced - None of above
The flexural strength (fr) of concrete measured from the bending test is always higherthan the direct tensile strength (ft). In reality, the stress in the cracked part of theconcrete is lower than ft. Also, failure may occur on the compressive side. Assuming1) there is no tension softening in the cracked zone, i.e., tensile stress stays at ft; and 2)infinitely large compressive strength, draw the stress distribution over the depth of thebeam at ultimate failure when the curvature of the section is approaching infinity. Withthis stress distribution, show that the upper bound of fr/ft is equal to 3. (Hint: On rotating the section, because the compressive stress can increase well beyondft, the neutral axis will continue to shift towards to the compression side.)
