摘要
采用带约束拉杆L形钢管混凝土截面简化方法,分别以统一理论、极限平衡理论和统一强度理论为基础,并考虑截面长宽比的影响,提出了带约束拉杆L形钢管混凝土轴压短柱承载力计算公式。计算值与试验值比较表明,以统一理论为基础的简化计算方法吻合较好。利用统一理论为基础的简化计算方法,对影响带约束拉杆L形钢管混凝土轴压柱受力性能的因素:拉杆纵向间距、拉杆横向间距、钢管壁厚和钢管屈服强度,进行正交分析,为工程设计及应用提供参考依据。
The cross section simplified method of L-shape CFT with binding bars was used,based on separately unified theory,limit equilibrium theory,unified strength theory and taking account of sectional length-width ratio,bearing capacity formula of L-shape CFT axial compression columns with binding bars was proposed.The results show a good agreement of test data with those by the simplified analysis method based on unified theory.The orthogonal analysis was done for the factors influencing the mechanical behaviors of L-shape CFT axial compression columns with binding bars using the simplified analysis method:such as longitudinal distance between binding bars,wall thickness of steel pipe and the yield strength of steel tube,which provided some useful references for design and application of projects.
