単層ラチスドームの形状初期不整の推定手法について

抄録

Initial imperfections caused by random member length errors are discussed to investigate how the impferfections appear over an entire surface of a single-layer latticed dome and what magnitude of forces is induced in constituent members. The method to evaluate the imperfections is based both on a matrix analysis and a Monte Carlo technique taken into account of some degree of joint looseness. The present procedure and the results from the numerical analysis will provide practical and effective informations when designers face to estimating the quantities of imperfections in a latticed dome at a design stage.
