Importance factor is a multiplier used to adjust the design load for different types of structures.

• It is used to account for the consequences of failure and the level of risk associated with the structure.

• It is based on the occupancy category, seismicity of the region, and the structural system used.

• Higher importance factors are used for structures with higher consequences of failure, such as hospitals and emergency re...read more

BMD stands for bending moment diagram which shows the variation of bending moment along the length of a beam under given loading.

• BMD is a graphical representation of the bending moment at different points along the length of a beam.

• It is used to determine the maximum bending moment and the location of maximum bending moment in a beam.

• BMD is plotted by taking the first derivative of the shear force diagram.

• The area unde...read more

Comp strength refers to the compressive strength of a material.

• It is the maximum compressive stress a material can withstand before failure.

• It is an important factor in designing structures that can withstand heavy loads.

• For example, the comp strength of concrete is typically measured in pounds per square inch (psi).

Cracks in concrete can be caused by various factors such as shrinkage, settlement, overloading, and temperature changes.

• Shrinkage due to drying and cooling of concrete

• Settlement of the foundation or subgrade

• Overloading beyond the capacity of the concrete

• Temperature changes causing expansion and contraction

• Chemical reactions causing corrosion or deterioration

• Improper mixing, placing, or curing of concrete

• Design flaws or...read more

There are several types of failure in structures, including collapse, deformation, and cracking.

• Collapse: when the structure completely gives way and falls apart

• Deformation: when the structure bends or warps under stress

• Cracking: when the structure develops cracks due to stress or other factors

• Other types of failure include buckling, fatigue, and corrosion

• Examples of failures include the collapse of the Tacoma Narrows ...read more

The ratio of M20 is 1:1.5:3

• M20 is a mix of concrete with a compressive strength of 20 MPa

• The ratio of M20 is 1 part cement : 1.5 parts sand : 3 parts aggregate

• This ratio is commonly used in construction for foundations, columns, and beams

M20 is a designation for a concrete mix with a compressive strength of 20 N/mm² after 28 days of curing.

• M stands for mix and refers to the mix ratio of cement, sand, and aggregate.

• 20 refers to the compressive strength of the concrete in N/mm² after 28 days of curing.

• M20 is a commonly used designation for concrete in construction projects.

The steps of structure design involve planning, analysis, design, and construction.

• Planning involves determining the purpose, location, and materials for the structure.

• Analysis involves calculating the loads and stresses the structure will experience.

• Design involves creating a detailed plan for the structure, including dimensions and materials.

• Construction involves building the structure according to the design plan.
