Description

Verification Method B1/VM4 provides a means of compliance with Building Code Clause B1 Structure.

This document covers the ultimate limit state design of foundations, including those of earth retaining structures. Methods are given for determining ultimate bearing and lateral sliding strengths.

Verification Method B1/VM4 can be found on page 51 of the provided document.

Scope

This document does not describe a means of determining the value of the soil parameters used in the document (e.g. cI, fI and su). The derivation of these parameters, which must be based on the most adverse moisture and groundwater conditions likely to occur, is outside of the scope of this verification method.

Serviceability limit state deformations are not covered in this document. The determination of such deformations and their acceptability to the design in question needs to be considered but is outside the scope of this document.

This document assumes general ground or slope stability and provides methods only for ensuring against local failure of the foundation. Overall ground stability needs to be verified before this document can be applied; this is outside the scope of this verification method.

This document must not be used to design foundations on loose sands, saturated dense sands or on cohesive soils having a sensitivity greater than 4.

This document shall not be used for foundations subject to continuous vibration.
