钢筋砼叠合梁受力特性分析

ANALYSIS OF THE BEHAVIOR OF REINFORCED. CONCRETE COMPOSITE BEAMS UNDER TWO STAGES OF LOADING

  • 摘要: 本文运用成熟的电算模拟方法;计算得到二阶段受力钢筋砼叠合梁在不同受力阶段的截面应力分布规律及钢筋的应力变化规律,分析得到二阶段受力时钢筋砼叠合梁[1]的受拉钢筋应力超前、受压区砼应变迟后逐渐缓解的实质为截面应力重分布的结果.

     

    Abstract: in this paper, with the available computer method, the authors have obtained the stress distribution across sections of reinforced concrete composite beams under two stages of loading, and show that the stress redistribution under two stages of loading results in a reduction of stress discrepancy in the tensile steel and of strain discrepancy in the compressed concrete between the composite beam and the corresponding casting beam.
