L/4 is the recommended spacing for bottom reinforcement from support and at midspan for top reinforcement.

• L/4 refers to one-fourth of the span length of a beam or slab.

• Bottom reinforcement is placed closer to the support to resist tension forces.

• Top reinforcement is placed at midspan to resist compression forces.

• Following the recommended spacing ensures proper distribution of forces and prevents failure.

• For example, if the span length is 12 meters, the bottom reinforcement sh...read more

Post tensioning and pre tensioning are techniques used in structural engineering to strengthen concrete structures.

• Post tensioning involves applying tension to cables or tendons after the concrete has hardened, creating compression in the concrete to increase its strength and reduce cracking.

• Pre tensioning involves tensioning the cables or tendons before pouring the concrete, allowing the concrete to bond to the tendons as it cures, resulting in a more efficient and cost-effe...read more

SFD and BMD show the variation of shear force and bending moment along the length of a simply supported beam for different loading cases.

• SFD (Shear Force Diagram) shows the variation of shear force along the length of the beam.

• BMD (Bending Moment Diagram) shows the variation of bending moment along the length of the beam.

• For a simply supported beam with a point load at the center, the SFD will be a triangular shape and the BMD will be a parabolic shape.

• For a uniformly distrib...read more

Modes of failures in columns and beams include buckling, crushing, and shearing.

• Buckling: occurs when a column fails due to excessive compressive stress causing it to bend or buckle.

• Crushing: happens when a column or beam fails due to excessive compressive stress causing it to crush or deform.

• Shearing: occurs when a beam fails due to excessive shear stress causing it to slide or break apart.

The mix ratio of M20 concrete is 1:1.5:3 (1 part cement, 1.5 parts sand, 3 parts aggregate)

• Mix ratio of M20 concrete is 1:1.5:3 (cement:sand:aggregate)

• This means for every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate are used

• Example: For 1 cubic meter of M20 concrete, 0.5 cubic meters of cement, 0.75 cubic meters of sand, and 1.5 cubic meters of aggregate are used

LSM stands for Limit State Method and WSM stands for Working Stress Method. Both are used in structural engineering for design purposes.

• LSM is based on the concept of safety against failure, while WSM is based on the concept of permissible stress.

• LSM considers the ultimate load carrying capacity of the structure, while WSM considers the working load on the structure.

• LSM is more commonly used in modern structural design due to its more accurate and reliable results.

• Example: LS...read more

SFD and BMD formulas are derived from equilibrium equations and bending moment equations.

• SFD (Shear Force Diagram) is derived from the equations of equilibrium, where the sum of forces in the vertical direction is zero.

• BMD (Bending Moment Diagram) is derived from the bending moment equations, which relate the external loads to the internal bending moments in a structure.

• The SFD shows the variation of shear force along the length of a beam, while the BMD shows the variation of...read more
