Title Pre-Stress Introduction Analysis of a Lattice Shell with Tensile Members
Author TMinger Wu,Hiroshi Ohmori,Mutsuro Sasakii
Summary In this paperEŒthe pre-stress introducing process of a lattice shell with tensile members is analyzed. The lattice shell is reinforced with tensile unit structures and cables. Every unit structure consists of tensile members and compressive members and is stabilized by introducing pre-stress through elongating a compressive member before it is installed to the lattice shell. Cables are also used to improve the out-plane stiffness of lattice shell. In this paperEŒthe equilibrium equations for unit structures and for the whole structure are formulated and the elongation of every jacking element and the tensile force of every cable are determined in order to introduce proper pre-stress into the system.
