Abstract
An arrangement is disclosed in which deflections and mechanical stresses in turbine low pressure casings are controlled by inserting struts between the turbine diaphragm ledge ring stages. Preferably, the struts are cylindrical in shape, although other different shapes can be used in accordance with the needs of different applications. The struts can be solid or hollow in construction, although preferably they are hollow to reduce the material needed to fabricate them. The struts are located around the turbine casing, as is required to connect together two ledge rings where there is high axial deflection in the casing.
