SEISMIC PERFORMANCE OF PRECAST PRESTRESSED BEAM-COLUMN CONCRETE CONNECTIONS

摘要：

This test researches one monolithic connection and 4 precast prestressed unbonded post-tensioned concrete connections under reversed cyclic loading. Such parameters as PT initial post-tensioning force, PT eccentric position and PT anchor length are discussed. Results of experiment indicate that these elements have desirable seismic characteristics, restoring characteristics and have an ability to undergo large nonlinear displacements with little damage. In this paper a detailed analysis as resilience, ductility, energy dissipation etc are carried out. The objective of this test is to develop guidelines for precast structure in regions of earthquake zone.
