Computation of Dead Load Structural Elements Dead Loads

This document provides a calculation of the dead loads for the structural elements of a 4-story building. It lists each element, its properties, dimensions, and weight calculated based on area and density. The total dead load is calculated for each floor by summing the weights of the slabs, walls, beams, columns and other elements. The largest contributors are the concrete slabs, with weights ranging from around 400 kN for the first floor up to 630 kN for the upper floors. The document aims to comprehensively account for all fixed structural and non-structural weights to inform structural design of the building.
