Theoretical Model and Method for Self-Excited Aerodynamic Forces of Long-Span Bridgeson, and emphasis is placed on self-excited aerodynamic force model and numerical identification of model‘s parameters, flutter derivatives. Through a serious analysis of the thin-plate cross section, the H-shaped section, and the closed box section, the main problems and the key prospects are conclu

A Step towards a Realistic Probabilistic Analysis of Buckling Loads of Bridgesy law is extended to live loads. The formulated relation is validated numerically for multiple imperfection pattern vectors subject to normally distributed live loads. A more realistic case is realized based on measured random traffic loads. Computational cost of stability analysis to investigate th

Parametric Resonance of the Free Hanging Marine Risers in Ultra-Deep Water Depthstion and exploitation moving to much deeper waters, risers play more important roles than before, and face with many technological challenges. The riser resonance can produce disastrous results, such as environment pollution and economical loss. In this work, firstly, the governing motion equation o

Effects of Concentrated Initial Stresses on Global Buckling of Platesne compression). At a certain given critical load the plate will buckle very sudden in the out-of-plane transverse direction. The destabilizing force could come from pure axial compression, bending moment, shear or local concentrated loads, or by a combination of these. If the structural element is

Application of a Thin-Walled Structure Theory in Dynamic Stability of Steel Radial Gatesces in many water-shorting places and the radial gates are need to operate partly for adjustment of discharge in these projects. However, the low head steel gate accident emerges increasingly one after another, due to the instability of radial gate arms under dynamic loading action. In this article,
