SHALLOW INTRODUCTION FOUNDATIONS
1 SHALLOW FOUNDATIONSA ssistant Prof. Berrak TEYMURINTRODUCTIONTo perform satisfactorily: The foundation has to be safe against overall shear failure in the soil that supports it. (bearing capacity) The foundation cannot undergo excessive displacement settlement. Design considerations FOUNDATIONS must be designed both structurally and geotechnically Able to safely carry compression, tension and shear loads, and possible moments Structurally efficient Geotechnically efficient Take tolerance of structure to movement into accountFOUNDATION TYPESSHALLOWSoil layer is suitable for supporting a structure ata relatively SHALLOW depthDEEPDEEPU pper layer of soil is not suitable to carry/supportUpper layer of soil is not suitable to carry/supporta structure.
