Background
The proportion of the existing newly-built building is gradually reduced, and the proportion of reinforcing and reforming the existing building is continuously increased. The earthquake-resistant performance of the existing buildings is degraded along with the increase of the service life, and the earthquake-resistant fortification standard of the buildings in China is improved along with the development of economy. Therefore, many existing buildings face the problems of insufficient earthquake-resistant performance and incapability of meeting earthquake-resistant safety. Therefore, a large number of existing buildings face the problem of seismic reinforcement in the future.
For the same existing building, the feasible earthquake-resistant reinforcing scheme is not only used, but also can be selected by a plurality of schemes. For example, in the existing buildings with insufficient earthquake resistance, an earthquake strengthening scheme for strengthening structural members can be adopted, an earthquake strengthening scheme for changing a structural system can be adopted, an earthquake strengthening scheme for seismic isolation technology can be adopted, or a plurality of strengthening methods are adopted to be mixed for use. Different anti-seismic reinforcing schemes can achieve the aims of improving the anti-seismic performance of the existing building and meeting the anti-seismic safety. But different earthquake-resistant reinforcement schemes may have great differences in the aspects of economy, construction convenience, applicability after reinforcement, green environmental protection and the like. Therefore, the earthquake-resistant reinforcement of the existing building needs to select a scheme with optimal comprehensive benefits from feasible alternatives. The problem of existing building earthquake-resistant reinforcement scheme selection is solved.

The scheme comparison and selection basically stays in a definite comparison and selection stage, and a quantitative comparison and selection method is lacked. The few earthquake-resistant reinforcement scheme selection adopting quantitative indexes is mainly just to carry out quantitative selection on earthquake-resistant reinforcement cost, and does not consider the convenience of reinforcement construction, the influence on building functions after reinforcement, the environmental protection and other factors. Only considering the quantitative comparison and selection method of the economic indexes, the selected scheme may have short boards or poor comprehensive benefits. At present, no scientific and reasonable quantitative comparison and selection method for the existing earthquake-resistant reinforcement scheme of the building exists in China.
Based on the above reasons, in order to ensure the smooth implementation of the existing building earthquake-resistant reinforcement engineering in China, realize scientific decision-making of the existing building earthquake-resistant reinforcement and achieve the goal of optimal comprehensive benefits, it is urgently needed to provide a multi-index quantitative comparison and selection method of the existing building earthquake-resistant reinforcement scheme, which is easy to realize, scientific, reasonable and strong in operability.
