✦ Synopsis
Ahatract-Different countries have produced codes for prestressed concrete poles for street lighting. An attempt is made to present au automated analysis to caMate the safety factors, rest&ant stresses, ultimate loads and forces against cracking in prestressed pole. Based on these results one can bring about a unified analysis in which a provision is made for a comparative study of all these codes.
