Design Standard for Foundations of Buildings and Structures
An interactive tool to explore TCVN 9362:2012. This standard specifies requirements for investigation, calculation, and design of foundations for civil and industrial construction projects. Understanding and correctly applying the standard is fundamental to the safety and sustainability of all structures.
Soil Classification and Geotechnical Properties
Soils are classified based on their physical and mechanical characteristics. Click on each soil type to view important geotechnical parameters specified in the standard.
Quick Calculation Tool
Apply formulas from the standard to quickly estimate the bearing capacity of the soil beneath a spread footing. This tool is for reference only and does not replace detailed design calculations by a qualified engineer.
Estimate Design Bearing Capacity (R)
Design Bearing Capacity (R):
– kPa
Formula (5.7) TCVN 9362:2012
R = m(A.b.γ + B.d.γ’ + D.c)
Limit States
Foundation design must be checked against two groups of limit states to ensure the structure is both safe regarding load-bearing capacity and stable during use.
Group I: Ultimate Limit States (ULS)
Calculations to ensure the foundation does not fail in strength or lose stability. This relates to bearing capacity, sliding stability, overturning, etc. The goal is to ensure the structure does not collapse.
Group II: Serviceability Limit States (SLS)
Calculations based on deformation to ensure normal operation of the structure. This relates to settlement, differential settlement, tilt, and other deformations not exceeding allowable limits, preventing structural cracking.
