Circular Base Plates with Large Eccentric Loads

Abstract

Circular base plates are commonly used for pipe columns, such as pylons in cable-stayed bridges, lighting poles, and electric power line posts. Although the explicit solutions for rectangular base plates can be found in many textbooks and AISC design procedures for base plates, a design procedure for circular base plates has not been documented. In this paper, two equilibrium equations are presented for circular base plates with large eccentric loads. Since these two equations cannot be solved explicitly, an iteration approach is used to solve them.
