为更好地分析有粘结、无粘结预应力混凝土框架结构的抗震性能,利用结构分析软件MIDAS CIVIL分别建立了有粘结、无粘结预应力混凝土框架结构,通过振型分解反应谱法研究了两种结构的动力特性与抗震性能.结果表明:对于预应力混凝土框架结构,在满足建筑结构抗震要求的前提下,应尽量选择有粘结预应力混凝土框架结构. In order to better analyze the seismic performance of the bonded and unbonded prestressed concrete frame structure, the structural analysis software MIDAS CIVIL was used to establish the bonded and unbonded prestressed concrete frame structure. The vibration mode decomposition response spectrum method The dynamic characteristics and the seismic performance of the two structures are studied.The results show that for the prestressed concrete frame structure, the prestressed concrete structure should be selected to meet the seismic requirements of the building structure.
