摘　　要：根据《型钢混凝土组合结构技术规程》中的型钢混凝土框架梁的计算假定,分别利用其中的简化公式和精确计算公式计算型钢混凝土梁的正截面承载力。对比分析计算结果,对该规程中框架梁正截面承载力计算公式的计算精度进行评定,分析了其适用范围,并提出适用范围更广更精确的正截面承载力计算公式。Based on the design assumption of frame beam in Technical specification for steel reinforced concrete composite structures （SSRC）, ultimate bearing moment capacities of SRC beams were calculated with both the simplified formulation recommended in SSRC and theoretical formulation. Analyzing the values calculated with the two method, the calculating precision and applicable range were studied for the for the formulation recommended in SSRC. A new formulation for calculating the ultimate moment capacity was presented which may be in more precision and in wider applicable range.
