MODELING IN FREE CAD

-
Free Cad is a 3D modelling application , and easy to use as it is downloaded free of cost and being easily to show the section view in 2D formate.
The above shown model and its section view is my first work on Free cad application. I really enjoy while working .

STEP-BY-STEP PROCEDURE FOR CALCULATION OF BEARING CAPACITY FROM STANDARD PENETRATION TEST VALUES OR N-VALUES

-
Image
HOW TO CALCULATE BEARING CAPACITY OF SHALLOW FOUNDATION IN SAND FROM SPT VALUES OR N-VALUES  (IS-6403) STEP-1 Perform standard penetration test  on the location for which you want to calculate bearing capacity. This is done as per standard procedure given in IS-2131. Standard penetration test must be done at every 75 cm in vertical direction. STEP-2 Decide the depth, width and length of foundation for initial calculation. This is a trial and error process. In the first attempt, you can never get the exact size of foundation which will satisfy all of your needs. STEP-3 Apply necessary  corrections to the standard penetration test values . Calculate the cumulative average value of corrected SPT values from the base level of foundation to a depth equal to 2 times the width of foundation. STEP-4 Correlate the above cumulative average SPT value with the fig given below to find out the corresponding angle of shearing resistance (ϕ). Relation between ph...

PEDESTAL DESIGN AND REINFORCEMENT

-
For small load carrying columns , the pedestals are designed without any reinforcement and with height less than three times its width. Generally hollow concrete blocks are used and the hollow place is filled with concrete. But this is only limited to small load ranges. But in the case of large load columns , construction and design of pedestals is same as reinforced columns for major loads. Reinforcement is also provided for the pedestals but the amount of reinforcement is 0.15% of its cross sectional area. Minimum reinforcement shall be 0.15% of crossection area (Refer clause 26.5.3.1 of IS 456 on pedestal having length less than 3*least lateral dimension) Minimum Bar dia - - Better use 12mm dia as minimum Maximum spacing - - 200mm (This is generally for mass concrete and the case of pedestal seems closer to it) Lateral ties - - Al around may be 10mm dia @200mm c/c maximum , But internal ties need to be provided ,may be ,at double spacing to connect opposite fa...

Etabs VS Staad

-
Etabs VS Staad Hello Everyone,😊  I am here after little bit long time. Today in this blog I am sharing my working experience on  Etabs and Staad. And compare these two software commonly used by structural engineers. 1- For small structures like up to 3-story buildings STAAD is easier to use and for beginners is easier to learn, but ETABS needs more inputs, which might be difficult to understand in initial stages. 2- On the other hand, more inputs in ETABS gives you more control of what the software outputs. Like Shear wall design, stiffness modifiers, mass source, restraints, diaphragm . . . 3- For high-rise structures, undoubtedly ETABS gives better results and reliability. In the world, you can find more iconic and famous high-rise buildings designed by ETABS. 4- Based on some comparisons I myself did, ETABS gives you 5-10% more economical design than STAAD. This claim has proved by the others. 5- There are more analytical options available in ETABS...
