Abstract

Circular base plates are commonly used for cylindrical columns; such as pylons in cabled-stayed bridges, lighting poles, electric power line posts, and even buildings. In some structures a little gap is considered between base plate and foundation. In this case compressive bolts which transmit compressive forces to the foundation are also considered in design of base plate. The purpose of this study is design of circular base plates on the effect of applying the axial load and large bending moment in the case that tensile and compressive forces are transmitted to foundation via bolts. An exact method has not been presented about design of this status yet, therefore in this study we can offer suitable method for design of circular base plates by expression of mathematic formulas. By considering the graphs in the end of this paper, can be concluded that, this status is very useful for axial force with large eccentric. In other words, this status for axial force with large eccentric gives little design thickness than the other status that a gap is not considered.
