Nonlinear Analysis of a Prestresseed Concrete Pole Section

This paper attacks the analysis of prestressed concrete structures. The attack is made assuming that the steel prestress members behave linearly and that the concrete is a nonlinear material obeying a second order stress-strain relationship. The entire analysis depends only on one empirical assumption and is developed from fundamental concepts of statics. The theoretical ground work is presented; and, then, a familiar example is solved. Additional theoretical development is presented as the solution of the example problem develops. This particular method of analysis presents an alternative to the empirically based ACI method.
