［摘要］通过对一榀有粘结预应力混凝土扁梁框架和一榀无粘结预应力混凝土扁梁框架所进行的拟动力抗震性能试验，分析比较了它们的破坏形态、动力反应、滞回曲线、刚度退化等抗震性能。试验结果表明，有粘结预应力混凝土扁梁框架和无粘结预应力混凝土扁梁框架的各种反应没有显著的差异。无粘结预应力混凝土扁梁框架应当可以满足抗震要求。

Abstract:The pseudodynamic tests of one bonded and one unbonded prestressed concrete flat beam frame have been carried out to research the failure pattern, dynamic response, hysteresis curves and rigidity degeneration. Based on the results of the tests, there is no obviously different response between bonded and unbonded prestressed concrete flat beam frames. The unbonded prestressed concrete flat beam frame can meet the aseismic requirement.

Keywords:prestressed concrete; flat beam frame; seismic behavior; pseudo-dynamic test
