基于望谟高速的预应力T梁静载实验,用透过法采集不同荷载作用下梁体腹板不同位置处的混凝土弹性模量,并对不同荷载情况下的混凝土弹性模量作了定量与定性分析,分析结果表明:第一级荷载与第二级荷载之间,混凝土弹性模量变化较大,而后逐级加载对混凝土弹性模量影响较小。
Based on the static load test of prestressed T-beam at Wangmu high speed, the elastic modulus of concrete at different positions of webs under different loads was collected by transmission method. The elastic modulus of concrete under different load was quantitatively and qualitatively analyzed The analysis results show that the elastic modulus of concrete varies greatly between the first load and the second load, and then the effect of progressive load on the elastic modulus of concrete is small.
