Some seismic strengthening suggestions based on the concrete reconstruction plan were put forward. It can give the structural test, seismic appraisal and strengthening of similar multilayer framework structures for reference.Keywords: existing architectural structure; test; identification; seismic strengthening作者简介：顾渭建，高级工程师，总工，Email:gwj3000@sina.com
