Civil Engineering Formulas PDF: Everything You Need to Know



Civil Engineering Formulas Free Download Pdf




Civil engineering is a branch of engineering that deals with the design, construction, and maintenance of structures such as buildings, bridges, roads, dams, and tunnels. Civil engineers use various mathematical formulas to perform calculations related to their projects. These formulas help them to determine the dimensions, quantities, loads, stresses, and other parameters of different components of a structure.

What are civil engineering formulas?




Civil engineering formulas are mathematical expressions that describe the relationships between different variables or quantities in civil engineering problems. They can be derived from physical laws, empirical observations, or theoretical models. They can be simple algebraic equations or complex differential equations.


Some examples of civil engineering formulas are:


  • The formula for calculating the force (F) on a beam due to a uniformly distributed load (w) over a span (L) is F = wL/2.



  • The formula for calculating the bearing capacity (q) of a soil layer with a cohesion (c), an angle of internal friction (φ), and an overburden pressure (σ) is q = cNc + σNq + 0.5γBNγ.



  • The formula for calculating the pressure (P) at a depth (h) in a fluid with a density (ρ) and a gravitational acceleration (g) is P = ρgh.



  • The formula for calculating the stress (σ) in a material due to an applied force (F) over an area (A) is σ = F/A.



  • The formula for calculating the water-cement ratio (w/c) of a concrete mix with a cement content (C), a water content (W), and an air content (A) is w/c = W/(C + A).
