Abstract: A lot of buildings have many structure-systems due to the insufficient prehension of structure-system and force transfer mechanism of designer. And this kind of design is rigidly forbidden by current criterion, for its irrational force transfer path. Framework and masonry structures have huge different seismic response, and it is liable to result in severe damage when merely considering structure deformation. Thus, tlus should be taken into consideration when reinforcing the anti-seismic capacity of buildings. Associated with actual engineering, the project of adding new anti-seismic slot was discussed when reinforcing tlus kind of buildings.
Keywords: anti-seismic reinforcement; structure-system; concrete and brick structure; frame structure, alteration
