【摘要】 本文通过21根叠合梁的试验研究,探讨了配筋钢纤维混凝土叠合梁正截面受力性能,分析了钢纤维的掺入对叠合梁受拉钢筋“应力超前”效应减缓的程度,提出了配筋钢纤维混凝土叠合梁受拉钢筋应力限值的公式。更多还原

【Abstract】 In this paper, the bearing properties of SFRC composite beams in flexure was inverstigated, and the effects of steel fibers on the phenomena of "stress excess of tensile steel" was analyzed, by testing 21 specimens of composite beam. The paper presented the formula for controlling the stress of tensile steel of SFRC composite beams.更多还原
