Buckling Behaviour of Thin-walled Composite Columns Using Generalised Beam Theory
نویسندگان
چکیده
An extension of the existing Generalised Beam Theory (GBT), intended to make it applicable to orthotropic thin-walled structural members, is presented and discussed. The derived equations are, then, used to analyse the local and global buckling behaviour of FRP pultruded columns and the GBT results are validated through a comparison with numerical ones, obtained by finite strip analyses. Finally, a parametric study is carried out to investigate the variation of the bifurcation stress and buckling mode nature with (i) the column length and cross-section dimensions and (ii) the composite material properties.

متن کاملPost-buckling and First-ply Failure of Thin-walled Frames and Columns Made of Composite Materials
First-ply failure (FPF) of composite thin-walled columns and frames is investigated in the buckled structure. Elastic behavior is assumed during the pre-buckling and buckling states, and along part of the post-buckling equilibrium path. The Tsai-Hill criterion is employed to identify failure of one ply at one specific location. The technique of analysis is based on evaluation of the post-buckli...

متن کاملNon-linear behaviour of thin-walled open section composite beams in lateral stability
An analytical study along with a numerical investigation is conducted to determine the lateral buckling strength of thin-walled open-section I shape composite beams. Based on Vlasov-type linear hypothesis beam stiffness coefficients, which account for a cross section geometry and material anisotropy of the section, are obtained. In this study the axial and bending coupling terms ( A,, , A,, , D...
متن کاملمعرفی ستون جدار نازک توخالی ساخته شده از ورقهای فولادی موجدار و بررسی رفتار لرزهای آن
Thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. Recent earthquakes, e.g. Hyogoken-Nanbu or Kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. This paper presents a new innovative thin-walled hollow steel column fabricated of corrugated plates, “thin-walled steel columns...
