Abstract:The analysis and design of the single-layer cable-net  curve curtain wall of China Maritime Museum are difficult. Lattice optimization and form-finding of the cable-net, finite element analysis of the complex joints, cable strength and anti-relaxation calculation, deformation calculation were introduced with ANSYS software to satisfy the shape and safety of the structure. The design of ball hinges at the end of the cables could be reference for other similar projects.

Keywords:curtain wall; curved cable-net; design; form-finding
