Structural Calculators

Calculate dead, live, wind, and environmental combination loads acting on structural framing members.

Compute maximum vertical deflection and slope for simply supported, cantilevered, and fixed beams.

Determine extreme fiber bending stress using elastic section modulus and maximum flexural moment values.

Evaluate shear force diagrams (SFD) and maximum shear stress distributions across structural spans.

Calculate elastic (Z) and plastic (S) section moduli for I-beams, rectangular hollow, circular, and channel sections.

Size standard structural steel W-shapes, S-beams, and channels according to AISC bending and shear limits.

Design singly and doubly reinforced concrete beams with required tensile rebar areas under ACI 318 codes.

Find Euler's critical buckling load (Pcr) and effective slenderness ratio based on pinned or fixed end conditions.

Calculate axial compression load capacity for short and slender reinforced concrete and structural steel columns.

Estimate mat foundation slab thickness, concrete volume, contact bearing pressure, and flexural reinforcement.

Evaluate cantilever retaining wall stability against soil lateral pressure, overturning moments, and sliding failure.

Analyze Pratt, Howe, and Fink truss internal member tension and compression forces using the method of joints.
