【Abstract】 From the point of view of load carrying, three schemes of rotating platform support are analyzed and compared with in this paper. The analytic result implies that it is an effective method to add swag rods at the end of main beams of rotating platform in order to reduce the moment load on these main beams and full joint supporting design plan is worth being recommended and promoted.更多还原
