Abstract
In response to rapid constructions for marine structures, the authors have conducted structural researches on composite prestressed concrete structures, which consist of precast concrete blocks and filled-in concrete and steel pipe piles. This method is secured by the bondage and bearing capabilities for the columns and beams joints, where columns of precast blocks and filled-in concrete are prestressed. Thus, this type of structure by its nature could not anchor the main reinforcing bars of beams into the columns. Therefore, the authors conducted the structural tests for the purpose of studying the behaviors of these special joints. The results of tests show that these joints could function as a joint of a rigid frame from ample transmittance of bending moments of beams into columns and no excessive displacements.
