Simplified equations for the strength and deflection of laterally loaded vertical posts embedded in soil foundations, using the modulus of subgrade reaction approach, are presented for simple post embedment and for posts with enlarged footings. Equations describing the elastic behaviour of similarly loaded embedded posts are also detailed. The aim of the paper is to provide a consolidated document containing information for the preliminary design of embedded posts prior to detailed geotechnical investigations and analysis or for the design of such posts where detailed investigations and analysis cannot be justified. The information provided in this paper is not generally available in basic soil mechanics textbooks.
