<p>This Architectural Drawing is of Column Size Detailing. <strong>The columns are designed to resist the axial loads and the lateral loads and transfer them effectively to the foundation of the structure</strong>. So, as all the loads from beams, slabs are transferred through the columns, it is important to design strong columns. Suppose we square column, so <strong>area of square =a2, hence a2 = 54925mm2, a=√54925mm2=234mm, width and depth of column =234mm×234mm, taking in round figure=230mm×300mm(9″×12″) for rectangular column</strong>. The distance between two reinforced columns ranges between 3-4 m for small buildings and 6-9 m for sizable facilities where large columns and free spaces are required. For ordinary structures, a distance of 5 m is appropriate, and <strong>the maximum span is 7.5</strong>, while the minimum is 2.5 m. For more information and knowledge download the drawing file.</p>
