Q1: For the design of a simply supported T-beam the ratio of the effective span to the overall depth of the beam is limited to

ANS:C - 20

In the design of simply supported T-beams, the ratio of the effective span to the overall depth of the beam is an essential consideration to ensure structural adequacy and performance. This ratio, often referred to as the "span-to-depth ratio," influences various aspects of beam behavior, including flexural and shear capacities, deflection control, and overall stability. The maximum permissible span-to-depth ratio for simply supported T-beams is typically governed by design codes and standards, which aim to ensure that beams are proportioned appropriately to withstand the anticipated loads without excessive deflection or structural failure. Among the options provided, the most common maximum permissible span-to-depth ratio for simply supported T-beams is: 2020 This ratio indicates that the effective span of the beam should not exceed 20 times its overall depth. Adhering to this limit helps maintain adequate stiffness and strength in the beam while preventing excessive deflections and ensuring structural stability. Design codes and standards, such as the ACI 318 (American Concrete Institute) or relevant national standards, often provide specific guidelines and limits for the span-to-depth ratio based on structural analysis and design considerations. It's essential to consult these standards to ensure compliance and optimize the design of simply supported T-beams for structural performance and safety.
