[關鍵詞] 鋼筋混凝土 疊合梁 均布荷載 斜截面承載力On the basis of test results, the effects of the composite coefficients, such as the depth ratio of precast section to composite section and the moment ratio of first-phase load to ultimate resistance load of precast section, on the shear resistance of reinforced concrete composite beams subject to two-phase uniformly distributed load are studied, Meanwhile, the calculation method is analyzed and proposed.
Keywords: reinforced concrete; composite beam; uniformly distributed load; shear resistance
