New progress and trends of studies and applications of precast concrete frame structure systems are summarized,and the applications of HPC concrete and new\|type reinforcements in precast concrete structures are promising.
This article first elaborated the articulation mechanism and the elastic-plasticity analysis method of the concrete frame construction , and in detail introduced principle and the process of the push-over analysis ;
Then has selected southeast university's earthquake resistance experiment of prestressed complex frame , then has carried on the elastic-plasticity static analysis with large-scale finite element analysis procedure SAP2000 to the experimental frame, and carries on the result and the experimental frame the contrast, proposed some design proposals, further confirm with it is feasible that the Push-over analysis method carry on the earthquake to the prestressed concrete frame construction to respond the analysis.
The eventual structural design and implementary scheme is that, the first two bottom floors adopted concrete frame construction, the seven other floors adopted frame structure of steel pole filled with concrete supported by steel pillar, and this structural design scheme was also introduced on emphasis.
This paper analyzes the influence of factors on earthquake action using method of comparing relative value,and represents the actions of factors that affect earthquake action on concrete frame construction,and can be a reference for structural design and teaching.
