Nonlinear Time History Analysis Of Prestressed Concrete Frame Beams And Suggestions For Anti-Seismic Design

Since the 1980s, the cast-in-place great span multi-layer prestressed concrete portal frame construction obtained the promotion and the application in our country. This kind of structure will be advantageous for the process unit to renew, to favor from now on the technological transformations, the frugal land, and will have the good economic efficiency. As one kind of load-bearing member, because it has the high cleavage resistance and the section rigidity under the accepted load, moreover the structure level altitude is low, therefore obtains the engineering universal affirmation.Along with the prestressed concrete portal frame construction in the earthquake country promoted application, its earthquake resistance question still received the engineering until now the attention. This question should solve from two aspects: First, continues the deep research prestressed concrete portal frame construction the earthquake resistance performance; second, research prestressed concrete portal frame construction earthquake resistance ability and design method.This article widely is reading the domestic and foreign related literature in the foundation, used the power time interval law to carry on the nonlinear analysis to a prestressed concrete frame, judged this pre-stressed frame, in different met under the earthquake wave action the power time interval to respond as well as the overall construction rarely consumes energy the mechanism, and GB50011-2001 made the appraisal based on present "Construction Aseismic design Standard" to its earthquake resistance target, finally to the prestressed concrete frame's aseismic design proposed several suggestions, supplied the later prestressed concrete frame the designer, the researcher referred to, the discussion.
