Load Bearing Capacity of a Footing

Dear Viewers,

Good Day !!! Hope you are fine & doing well at your professional life.

Today, I am going to discuss about "How to determine actual load bearing capacity & ultimate load bearing capacity of a Footing Foundation by using SPT value from Bore Hole Chart".

Lets Start,
To determine actual load bearing capacity & ultimate load bearing capacity of a Footing Foundation by using SPT value,
two types of Formula will be required,
---Meyerhoof's Formula
---Bowel's Formula

Lets see the following pictures of details calculation,

Page:02 - Bore Hole Chart (to use SPT Value)

Page:03 - Calculation details by using Meyerhoof's Formula

Page:04 - Calculation details by using Bowel's Formula

Dear Viewers,

today we have learned "How to determine actual load bearing capacity & ultimate load bearing capacity of a Footing Foundation by using SPT value from Bore Hole Chart",

My next article will be "How to determine actual load bearing capacity & ultimate load bearing capacity of a Pile Foundation by using SPT value from Bore Hole Chart",

Will be right back to you soon.
Take Care.
Good-Bye.

Have a nice day !!!

Response Spectrum Analysis (Dynamic Analysis) by STAAD. Pro

Response Spectrum Analysis (Dynamic Analysis) by using STAAD Pro :

Hello Viewer,

Hope you are fine & doing your best at your study & professional field.

Today I am going to describe you about the Response Spectrum Analysis (Dynamic Analysis) by using STAAD.Pro software.

Methodology: The design lateral forces at each floor in each mode is computed by STAAD in accordance with IS-1893. Please see the following pictures (my hand-notes) for details procedure.

Picture: 01

The values of (sa/g) can be calculated by Time Period (T) or, Damping Percentage (%).
At first by using, Time Period (T),
