PRESTRESSED CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a prestressed concrete structure capable of raising the effect of prestress in the prestressed concrete structure constructing tendon in the direction passing through an uneven step section of a stepped floor slab. SOLUTION: The prestressed concrete structure includes a member 1 having the first the center of gravity fixed section 11, the second center of gravity fixed section 12 and a joint section 18 and the tendon extending the inside of the member 1 in the direction across the uneven step. The tendon has the first and second tension sections 21 and 22 and connecting section 24 connecting the first and second tension sections 21 and 22, the first tension section 21 is extended in the direction across at least a part of the first center of gravity fixed section 11, and the second tension section 22 is extended in the direction across at least a part of the second center of gravity fixed section 12. The second connecting point 27 connecting the connecting section 24 to the second tension section 22 is in a domain 44 on the lower part side in the direction of load among domains partitioned by a tangent line 28 of the first tension section 21 passing through the first connecting point 26 connecting the connecting section 24 to the first tension section 21.
