For deflection calculations of reinforced concrete beams, which of the following statements is true: The most common factored load combination to be used for deflection calculations is 1.2 for dead loads and 1.6 for live loads. Camber must be introduced in all beam designs to compensate for the initial beam deflections due to dead loads In most beam designs, the dead load deflections are more important than the live load deflections Deflections of reinforced concrete beams need to be calculated based on a varying effective moment of Inertia corresponding to the level of loading due to the different amounts of cracking

Load and resistance factor design

Load and resistance factors design (LRFD), also known as Limit state design (LSD), refers to the design method used in building engineering. A boundary condition is a condition of a structure where it can no longer meet the relevant design requirements. The condition may refer to the load level or other actions on the structure, while the terms refer to the integrity of the structure, suitability for use, durability, or other design requirements. A structure designed for LRFD is limited to keeping track of all possible actions during its design time and is always ready for use, with the appropriate level of reliability in each boundary condition. LRFD-based construction codes clearly define the appropriate levels of reliability in their instructions.
