Discussion of Different Methods of Strengthening Masonry Walls with Constructional Column
With the rapid development of economy and the civil engineering discipline, the seismic performance of existing masonry wall cant satisfy the codes and regional seismic requirements.As a result, strengthening the earthquake resistance of it is put on the agenda.Using large-scale finite element sofiware-abaqus, this paper analyzes different methods of strengthening masonry walls by constructional columns.Under the premise of the cross area of the columns used to reinforce is identical, it shows that the wall strengthened by bilateral constructional columns has a better seismic performance than by unilateral constructional column.The ductility coefficient of the former increases 49.4% than the original masonry, while the latter increases 26.3%.The bilateral constructional column could significantly improve the integrity and ductility of the masonry wall, so does the seismic performance.It has engineering sense for the strengthening work.
