  Design Procedure for One Way Slab Here are the steps for the Design Procedure for One Way Slab in steps.For those who do not know what are the design requirements of a slab design  There are two types of slab classification based on the direction of bending occurs in these slabs.The two classifications are one-way slab and two-way slab.The basic difference between these slabs are one-way slab bends only in one direction and two-way slab bends in two directions as shown in the below figure.  Design Procedure Steps for One Way Slab 1.Based on the stiffness requirement assume suitable depth and calculate the effective span 2.Calculate the loads acting on the slab. 3.Calculate factored moment and shear force by considering the one-meter width of the slab  For simply supported slab  Factored moment =Mu= Wu× l²/ 8 Shear Force = Vu = Wu×l / 2 4.Determine the minimum depth required to resist bending moment by equating  Mu= Mulim = k×fck×bd² b=1000mm k=0.138 For F...

you model the soil using Area spring/spring properties and the software will capture the interaction between the foundation element and the soil. This approach will give you a better understanding and design moment or shear specially for mat foundations. I have some tips: Tip 1: In the absence of plate load test result you can use an approximate method to determine the soil su bgrade reaction. Bowels has proposed the following equation, Ks=40*SF*σall (SF-safety factor, σall allowable bearing capacity). Tip 2: don’t reinforce your mat or footings with the maximum moment around columns. Since the design moment is located at the face of column, at least try to read the moment at the face of column. Otherwise you would reinforce your mat for peak moment and end up being uneconomical. Tip 3: don’t forget to model the lateral passive earth pressure preventing your footing from sliding. Otherwise your model would be unstable. Tip 4: If you are using SAFE, you can model the soil with “soi...
