Influence of Local Members Strengthening on Overall Performance of Reinforced Concrete Frame Structure
Taking the typical school building of reinforced concrete frame structure as a research object
the influence of local members strengthening on the overall performance of the typical school building of reinforced concrete frame structure was explored by finite element software SAP2000.The contents cover the static lateral stiffness of the whole reinforced concrete frame structure
the dynamic performance of the whole frame
response spectrum analysis
static nonlinear analysis(pushover analysis) and the calculation of linear time history under three different earthquake records.The results show that the local member strengthening greatly affects the static lateral stiffness of the whole frame
the dynamic performance
story drift ratio
the peak of internal forces under standard earthquake spectrum of current Chinese code
appearing order of plastic hinge
node response spectrum under three different earthquakes
and the yield order of members when the earthquake happens.Much attention should be paid to it in practical projects.
