摘要
对于两跨及三跨的钢与混凝土连续组合梁 ,提出简化塑性理论 ,推导出集中荷载下梁负弯矩区极限抵抗矩及极限荷载的计算公式 ,给出连续组合梁调幅系数的确定方法 ,对比组合梁实测与与计算的负弯矩区极限抵抗矩、极限荷载及调幅系数 ,误差分别为 7% ,10 %和 2 0 % ·
A simplified plasticity theory was presented. For two span and three span steel concrete continuous composite beams. Formulas were put forward for calculating ultimate resisting moment on negative moment region and limit load of beams. The amplitude modulation coefficient was obtained. The difference between the experimental and computation of the results of the ultimate resisting moment,the load and the amplitude modulation coefficient is whin 7%,10% and 20% respectively.
