Supplementary data of the paper “DIRECT STRENGTH METHOD PREDICTION OF CFS FIXED-ENDED SINGLY-SYMMETRIC COLUMNS BUCKLING IN FLEXURAL-TORSIONAL MODES”

These supplementary data to the above article consist of seven tables (I.1 to I.7) concerning all the columns analysed (i) in reference [11] of the article (Tables I.1 and I.2) and (ii) in this work (see Table 2 of the article − Tables I.3 to I.7). Each table deals with columns exhibiting one (out seven) cross-section shape, namely: plain channels (U), lipped channels (C), hat-sections (H), rack-sections (R), return lipped channels (RLC), web-stiffened lipped channels (WSC) and web-flange-stiffened lipped channels (WFSC). Within each table, there are several “sub-tables”, each one concerning a specific selected column geometry (cross-section dimensions and length) – the lengths selected can be found in reference [11] of the article (U and C columns) or in its Table 2 (all the other columns). Each “sub-table” comprises five rows, corresponding to the 5 yield stresses (fy=150-300-450-600-750 MPa) considered for each column – each row contains the column (i) buckling loads (Pcr.FT, Pb.Fm) and their ratio RG, (ii) flexural-torsional (FT) slenderness (λFT), (iii) numerical failure load (Pu) and (iv) numerical failure-to-predicted load ratios (Pu/PnG, Pu/PnFT, Pu/PnFT-Fm).前文所述论文的补充数据集包含7张表格（编号I.1至I.7），涵盖两类经分析的柱构件：其一为该论文参考文献[11]中涉及的柱（对应表格I.1与I.2）；其二为本研究中分析的柱（对应论文表2——表格I.3至I.7）。每张表格对应七种截面形式中的一种，具体包括：平槽型钢（U）、卷边槽钢（C）、帽形截面（H）、齿条截面（R）、回卷边槽钢（RLC）、腹板加劲卷边槽钢（WSC）以及腹板-翼缘加劲卷边槽钢（WFSC）。每张主表格内包含若干子表格，每个子表格对应一种选定的特定柱几何参数（含截面尺寸与长度）——选定的柱长可查阅该论文的参考文献[11]（U型与C型柱）或其表2（其余所有类型柱）。每个子表格包含五行数据，分别对应单根柱所采用的5种屈服应力（fy=150-300-450-600-750 MPa）。每一行数据包含：(i) 柱的屈曲荷载（Pcr.FT、Pb.Fm）及其比值RG；(ii) 弯扭（FT）长细比（λFT）；(iii) 数值模拟破坏荷载（Pu）；(iv) 数值模拟破坏荷载与理论预测荷载的比值（Pu/PnG、Pu/PnFT、Pu/PnFT-Fm）。
