Column Load Calculation using Catchment / Tributary Area Method (Step-by-Step)
In this video, I break down exactly how to calculate the axial load on a column using the Catchment Area (or Tributary Area) method. This is a fundamental skill for every civil engineer and architecture student, serving as the basis for manual structural design and a critical check for software results.
💡 Why is this important? Even in the age of ETABS and SAP2000, understanding manual load calculations is essential for verifying computer models and developing a "feel" for the structure. This method helps you quickly estimate column sizes during the preliminary design phase.
