Dead Load Tributary Area Calculator

Calculate dead load from tributary area: P = w·A_t. Unit weights: concrete 24 kN/m³, steel 78.5, wood 5-6. Floor dead loads: 1.5-3.0 kPa typical. Roof dead load 1.0-2.0 kPa. Self-weight, superimposed dead load components.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate dead load from tributary area: P = w·A_t. Unit weights: concrete 24 kN/m³, steel 78.5, wood 5-6. Floor dead loads: 1.5-3.0 kPa typical. Roof dead load 1.0-2.0 kPa. Self-weight, superimposed dead load components

Each component has a specific meaning:

  • Tributary area: P = w·A_t — The tributary area: p = w·a_t recorded for the patient or scenario being assessed.

Note: Interpret the dead load result against the clinical thresholds and context described above.

How to Use

Enter the tributary area: P = w·A_t for the patient or scenario you are assessing. Calculate dead load from tributary area: P = w·A_t. Unit weights: concrete 24 kN/m³, steel 78.5, wood 5-6. Floor dead loads: 1.5-3.0 kPa typical. Roof dead load 1.0-2.0 kPa. Self-weight, superimposed dead load components. Use the dead load result to inform your clinical assessment.
