Section Size: W200X36: Refer Appendix D For Support Reactions

The document provides details of the dimensions and calculations for a base plate and column connection. It includes: 1) Dimensions of the W200X36 structural section and base plate including width, depth, thickness, anchor bolt size and spacing. 2) Calculations of the required base plate thickness based on bearing stress, tension criteria from anchor bolts, and moment demand. 3) Calculation of weld sizes required to connect the base plate to the column and checking the weld shear capacity. 4) A table of standard W-shape sections including flange and web thicknesses. 5) Dimensions and volume of a water well including diameter, depth, water depth.
