BEHAVIOR OF CONTINUOUS COMPOSITE MEMBERS UTILIZING PRECAST-PRESTRESSED CONCRETE RODS AS REINFORCEMENT.

摘要

An experimental and analytical investigation was made concerning the improvement of continuous prestressed concrete structures. The type of members selected for study were a double cantilever specimen and a multiple span girder. Of prime importance in this investigation were the effectiveness and practicality of using precast-prestressed concrete reinforcing rods to develop the continuity bending moment at the section where precast-prestressed elements were joined. For both of the specimens tested in this study,two precast beams were made continuous for negative moment at an interior support.
