Wind-Induced Response Analysis and Wind-Resistant Design of Hyperbolic Paraboloid Cable Net Structures

Abstract

Cable net structures, as a kind of light and flexible structures are very sensitive to wind excitations. The wind-induced response analysis and wind-resistant design are studied systematically in this paper. The main subjects studied are as follows: (1) the fundamental equations of cable structures; (2) a method for displacement response analysis of cable structures; (3) the formulae for computing inner forces in cable elements; (4) the expression of dynamic coefficients for displacement and inner force of cable structures as a geometrically nonlinear system; (5) numerical parameter analysis of H. P. cable net structures and the determination of dynamic coefficients.
