摘要
阐述了两点对称荷载作用下钢-混凝土简支组合梁截面沿高度应变变化规律的试验结果。利用弹性分析理论,建立适合于在跨中两点对称荷载作用下钢-混凝土简支组合梁交界面滑移的计算公式。结果表明,按照本文公式得到的计算值与实测值吻合良好。
On the basis of test research of steel and concrete simply supported composite beams, we get the midspan load-deflection curve. Based on the theory of elastic analyzes,we can establish the calculation formula of interface slip of steal and concrete simply supported composite beams which adapt to its bear symmetrical loading. The predicted values are in good agreement with experimental results.
