预应力混凝土框架结构抗侧能力与结构位移延性的关系

THE RELATIONSHIP OF THE RESISTANCE CAPACITY OF LATERAL LOAD AND THE DISPLACEMENT DUCTILITY OF PRESTRESSED CONCRETE FRAME STRUCTURES

PUSHOVER分析可以得到罕遇水平地震作用下结构的耗能机制和位移延性 ,结构在罕遇地震下需要的位移量可以通过能量原理计算得到 。

The energy dissipation mechanism and the displacement ductility of structures under the major earthquakes can be concluded by PUSHOVER analysis,the displacement of structures which is needed under the major earthquakes can be calculated with energy theory,PUSHOVER analysis can be used to evaluate the aseismic capacity of the prestressed concrete frame structures.
