1. First of all, you need to understand how to design the slab on grade (SOG) through hand calculations. Later on, you may develop a spreadsheet or use some patent software to do it using a computer. 2. The references given above provide design methods (pca, WRI, COE etc), dealing with different types of SOG (e.g., unreinforced, reinforced concrete, post-tensioned etc.) subjected to various types of loads (uniform, line, wheel & post loads). 3. Before starting the design, you will need to go through the reference available with you (i.e., ACI 360), and a. Select the SOG type from the Section 7 onwards, applicable to your case. b. Study the design requirements from the relevant section c. Determine the type and intensity of various loads, the slab will be subjected to during service. d. Solve the relevant design examples, given in the appendices of ACI 360 to understand various design parameters, charts, equations & their application to the design. e. Using the design prameters applicable to your slab, design the SOG by following the procedure adopted in the reference design example. HTH Regards.

Hello, I'd like to contribute to this forum three excel sheets of my design, Nothing too fancy but that's what I'm capable of The first is a singly reinforced concrete beam - one layer. (Don't use the shear design it's not complete) with ACI 318-14 The second is a hollow core pretension-ed slab analysis using PCI to check the stresses limits, design strength and Mcrack The third excel is an analysis method for seismic design of reinforced concrete water containing structures. ( I've done this very recently if you spot any error in it please inform me ) with ACI 350.3-06 and IBC/ ASCE 7-10 Sheets.rar
