钢筋混凝土连续梁弹塑性弯矩系数研究

THE INVESTIGATION OF THE ELASTO-PLASTIC MOMENT COEFFICIENTS FOR REINFORCED CONCRETE CONTINUOUS BEAMS

试验验证表明,用二次规划求解的强迫转角法是进行钢筋混凝土连续梁弹塑性分析的有效方法。应用该方法对承受均布荷载和集中荷载的连续梁弹塑性弯矩值进行了计算模拟试验,总结出一套供设计使用的弯矩系数建议值。

Some experiments show that the 'imposed rotation method' derived from quadratic programming is a useful method in elasto-plastic analysis of reinforced concrete continuous beams. With it, a great number of simulating calculation tests were made for elasto-plastic moments of continuous beams under uniform load and concentrated load. Finally, this paper gives a set of recommended values of elasto-plastic moment coefficients for use in designing reinforced concrete continuous beams.
