Q1: A pre-stressed concrete memberA is made of concrete
B is made of reinforced concrete
C is stressed after casting
D possesses internal stresses.
ANS:D - possesses internal stresses. A pre-stressed concrete member possesses internal stresses, making it distinct from traditional reinforced concrete members. Pre-stressed concrete is a construction material in which internal stresses are deliberately induced in a structure before it is subjected to external loading. These internal stresses are introduced to counteract the tensile stresses that will develop when the member is subjected to external loads, such as bending or axial loads. Pre-stressing is typically achieved by tensioning high-strength steel tendons or cables within the concrete member before it sets and hardens. Once the concrete has hardened, the tendons are anchored, transferring the pre-stress force to the concrete. This process places the concrete in a state of compression, which improves its resistance to tensile stresses. The key characteristics of a pre-stressed concrete member include:
