In order to meet the special requirements of architecture functions, partial joint displacements and local joint connecting methods cannot meet the provisions of current codes. Nonlinear finite element calculations and the overall stability analysis of lattice shells prove that the lattice shell structure is safe and economical.Keywords: single cable curtain wall; nonlinear analysis; stability analysis; structural deformation and control作者簡介：鄭良知，高級工程師，一級注冊結(jié)構(gòu)工程師，Email：zjlzzheng@126.com。
