【Abstract】 High strength prestressed concrete electricity poles with large diameter are being widely used in high voltage transmitted electricity circuitry projects.Asked for the need of practice,papers studies the circularity members’ ultimate capacity and deflects by means of full process analysis method.The members’ property governed by the parameters of section dimension、effective prestressing force、concrete strength and so on are discussed.And all of the conclusions are primarily in agree with test results.Finally,Some suggestion is brought forward to advance the members’ flexural ductility.更多还原
