摘要

针对预应力混凝土框架结构,建立了空间框架有限元模型并进行了非线性动力时程分析,得出三种地震波作用下结构的自振特性、结构变形、裂缝开展情况,与实测结果基本吻合。结果表明,框架的第1层和第2层梁柱为薄弱环节,但结构能保持较好的整体性,能满足七度地震区的抗震使用要求。
On prestressed concrete frame structure,the finite element model of space frame was established and nonlinear dynamic time history analysis was completed under three seismic waves.The natural vibration characteristic,deformation and crack growth were obtained,which corre-sponded with experimental results.It shows that the beam and column ends of the 1st and 2nd floor were the vulnerable area.The structure could maintain integrity and the aseismic performance of the frame under seven degrees of small and frequently occurred earthquakes,which could fulfil the operating requirements.
