| 摘 要： | 针对FRP等距环肋加强的钢管混凝土柱,将FRP环肋与钢管间的集中线荷载展为沿轴向变化的富氏级数,将应力和位移看作一组"初等解"和一组"修正解"的叠加;"初等解"即为一般的二维理论所得的解答,而"修正解"应用勒夫(Love)位移函数法求得.并用FRP环肋与钢管表面位移连续条件,确定FRP环肋与钢管相互作用的未知线荷载,由此求得该问题的弹性理论解.通过计算实例表明,解的收敛性良好.

| Abstract: | Based on theory of cylinders subjected to uniform internal pressure,the mechanical performance of a steel tubular column filled with equidistant fiber reinforced polymer (FRP)-ring-stiffening concrete is investigated. The solutions for the stress and displacement are regarded as the superposition of elementary and improved solutions. The elementary solutions are found by using two-dimensional elastic theory. The improved solutions are found by using the Love displacement function method. Considering the con... |
