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.
