Abstract

This paper investigated earthquake responses of the latticed domes supported with braces of deteriorated stress-strain relationships due to buckling, followed by a proposal for estimation method of static seismic loads. The method for proposal is based on an equivalent linearization method, where nonlinear stress-strain relationships are linearized using an equivalent stiffness. First, two main modes, obtained in the equivalent linearization, were selected and superposed for representing the dynamic behavior, and two types of static seismic load depending on the intensities of input earthquake motions were proposed: One is a seismic load considering mainly the effects of horizontal sway motions and the other one is a seismic load reflecting the effects of the anti-symmetric motions induced by horizontal earthquake motions. Second, the seismic loads were applied in the pushover analysis of the domes, and the responses were compared with those calculated using a time history dynamic analysis. Finally, the proposed method was proved accurate and efficient for estimating static seismic loads as well as for structural proportioning of the members of latticed domes.
