Both lower towers and higher towers in the environmental protection cover are connected structures with floors connected in upper stories. The buildings are irregular in plane and elevation and have complicated mechanical conditions with supported environmental protection cover on four towers. The corresponding performance-based seismic precautionary objectives of the structure were proposed. According to conceptual design, calculation results combined with the requirements of the code, seismic strengthen measures of the structure were adopted to improve the bearing capacity and ductility of components to form reasonable structure failure mechanism and improve the seismic performance of the whole structure.Keywords: environmental protection cover; connected structure; sway column; support; seismic performance作者簡介：靳海卿，學士，一級注冊結(jié)構(gòu)工程師，Email：jif3137@hotmail.com。
