【摘要】 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.更多还原

【Abstract】 In order to better analysis of seismic performance of the bonded and unbonded prestressed concrete frame structure,this paper established bonded and unbonded prestressed concrete frame structure respectively using the structure analysis software MIDAS CIVI,and studied the dynamic characteristics and seismic performance of two kinds of structures by the modal decomposition response spectrum method.The results show that for prestressed concrete frame structures,on the premise of meet the requirements of building structure seismic,bonded prestressed concrete frame structure should be chosen as long as it meets the prerequisites of seismic building structure.更多还原
