Abstract: The analysis of moments to prestressed concrete statically indeterminate beams is examined. The second moments of two-span and three-span prestressed continuous beams should be calculated under the uniform loads and concentrated loads. The locations of prestressed reinforcements arrangement should be obtained, which will satisfy the demands on cracking resisting of pretensioned area for prestressed concrete members in the condition of construction stage based on concrete structure design code, which also provides a basis for arrang ing the prestressing reinforcements of such sort of beams.
