摘要
利用能量变分法推导出均布线荷载作用下新型GFRP组合梁翼缘有效分布宽度的理论公式,通过有限元数值模拟验证理论公式可靠性。并借鉴传统钢-混凝土组合梁分析方法,对新型GFRP组合梁翼缘有效分布宽度各种影响因素进行了参数分析。
The energy variation method is used to derive the theoretic formula for effective distribution width of flange of the new type of GFRP composite beam under uniform linear load and the reliability of the formula is verified by finite element numerical simulation. With reference to the analysis methods for conventional steel and concrete composite beams, the parametric analysis is further made in order to investigate various factors that affect the effective distribution width of the flange of the composite beam.
