Abstract:During the structural design of reinforcement and reconstruction for Pudong Grand Hotel, design idea of system strengthening was adopted and buckling\|restrained brace(BRB) system was used to make the structure meet the requirements of the current code for seismic design effectively, and to reduce the number of structure members which have to be reinforced, so as to shorten the reconstruction time. Combined strengthening method and static\|pressing pile foundation with anchor bolts strengthening method used in Pudong Grand Hotel were introduced. In addition, joint construction and large\|span steel canopy were presented.
Keywords:reinforcement;  reconstruction; buckling\|restrained brace; joint construction
