Welcome to Civilnirman. Starting anything one should have some experience in that chosen field. Passing Engineering and being an Engineer is different and hence in spite of basics, being taught application of the same has to be learned by being trainee with an experienced person. So Civil Nirman is here to upgrade your skills and fundamental knowledge in Structure design field by Industrial professionals.

Attached is the sample problem to Help you understand logic behind Teng's Chart, if you wanted to understand this manual refer links in You tube Videos watch all 4 parts.

Explore the high-level illustrations showing why the common P/A +M/Z formulas fail under specific conditions, helping you understand the root of calculation errors instantly. It includes two documents and Session from you tube class

Ever wonder why you can't just use $P/A$ for every footing design? 🤔 In Part 1 of our "Mastering Foundation Design" series, we break down the hidden danger of **Eccentric Loading**.

In the real world, columns don't just push down—they resist moments from wind and earthquakes, pushing the load off-center ($e = M/P$) [1], [2].

**In this video, you will learn:**
*   ✅ **The Trap:** Why the standard flexural formula ($P/A \pm M/Z$) creates dangerous errors when soil tension occurs [2], [3].
*   ✅ **The Rule:** What is the **"Kern"** or "Middle Third"? (If $e greater than L/6$, you have a problem!) [4], [5].
*   ✅ **The Reality:** Why soil is like a stack of bricks, not a solid beam—it cannot "pull" back down [3].

Mastering Foundation Design: The Teng’s Chart Method|Part 1 Basics of EccentricLoading & The "Kern"

Learn the practical application of Teng’s Chart for rectangular footing design in this step-by-step tutorial. In Part 2 of our "Mastering Foundation Design" series, we dive into a detailed design example focusing on Case 1: Small Eccentricity (where the load is within the kern/core).
In this video, you will learn:
• The 5 Design Steps: From calculating total vertical load to computing maximum pressure.
• Eccentricity Ratios: How to calculate longitudinal (e/L) and transverse (e/B) eccentricity based on column moments.
• Finding Coefficient K: How to use the interaction point on Teng's Chart to determine the K value for footings without uplift.
• Final Calculation: Using the master formula (P = K * Q / A) to ensure your maximum soil pressure is safe against allowable bearing capacity.
Example parameters covered:
• Footing Size: 2.6m x 3.15m
• Column Load: 768.61 kN
• Result: Safe design with pressure less than Allowable Bearing Capacity.

How to Calculate Maximum Soil Pressure Using Teng’s Chart | Part 2

What happens when a storm hits and your foundation load shifts outside the "Middle Third" (Kern)? 🏗️📉

In Part 3 of our Foundation Design Masterclass, we enter the "Danger Zone." When eccentricity (e) exceeds the limit of L/6, standard engineering formulas (P/A +/- M/Z) fail because they calculate negative pressure—implying the soil is pulling the footing down. Since soil cannot take tension, this leads to **Uplift**.

**In this video, we cover:**
*   ✅ **The Failure Point:** Why standard math becomes invalid when eccentricity is greater than L/6.
*   ✅ **Teng’s Chart Cases:** How to identify and calculate **Case II** (Linear Uplift), **Case III** (Corner Uplift), and **Case IV** (Instability).
*   ✅ **The Hydrostatic Analogy:** Understanding how soil pressure behaves like fluid on a submerged plate when contact is lost.
*   ✅ **Calculation Example:** Solving for the pressure coefficient K when the neutral axis cuts across the footing.

Stop guessing with standard formulas. Learn how to use Wayne C. Teng’s graphical method to accurately predict soil pressure when the footing lifts off the ground.

Title: Foundation Stability Checks: Overturning & Sliding (Part 4)
Description: Welcome to the final episode of our Foundation Design Masterclass!
 Calculating safe soil pressure using Teng's Chart is only half the battle
. Even if the soil is strong enough to support the weight, your foundation could still fail catastrophically by tipping over (overturning) or sliding sideways across the ground
.
In Part 4, we walk through the critical Stability Checks required to finalize and approve your footing design
.
In this video, you will learn:
Overturning Stability: How to calculate the Factor of Safety (FOS) by comparing the Resisting Moment (gravity and dead weight) to the Overturning Moment (wind or seismic loads)
.
Sliding Stability: How to balance horizontal shear forces against soil friction and passive earth pressure
.
The "Useful Width" (Effective Area): A crucial concept for geotechnical engineers, showing how to calculate the reduced effective dimensions (B' and L') of an eccentrically loaded footing to check ultimate bearing capacity
.
Final Workflow: A complete, step-by-step summary checklist of the entire Teng's Chart foundation design process
.
Ensure your structures are completely safe from every angle. Thank you for following along with this complete masterclass series!
