An old factory building needs to be reinforced and reconstructed on the basis of the original structure due to disrepair and changes in use functions.In order to make the reconstructed old factory buildings meet the seismic performance requirements,the construction concept of"combination of permanent and temporary reinforcements"is adopted for the whole construction process.Based on the finite element software ABAQUS,a three-dimensional refined nonlinear finite element numerical model of the old factory building during construction and after completion is established,and its seismic performance and reinforcement effect are evaluated.The results show that under the action of frequent and rare earthquakes of the local fortification intensity,the seismic performance of the old factory buildings after renovation and reinforcement has been greatly improved,and the old factory buildings during construction and after completion meet the seismic fortification goals.The reinforcement measures in the whole construction process are feasible and effective.
