摘要
为了研究实腹式型钢混凝土梁(SSRCB)在弯扭作用下的受力性能,进行了6根实腹式型钢混凝土梁和1根钢筋混凝土对照梁弯扭试验。通过试验研究,揭示了实腹式型钢混凝土梁在弯扭复合作用下的受力机理与破坏形态,分析了实腹式型钢混凝土梁弯扭性能的影响因素;提出了弯扭作用下实腹式型钢混凝土梁开裂扭矩和极限扭矩的计算公式,计算结果与试验结果吻合较好。
Abstract: In order to study the bending torsional of steel reinforced concrete beams (SSRCB), experiments were conducted on six solid web steel reinforced concrete beams and one reinforced concrete beam. The experiment reveals the working mechanism and failure modes of SSRCB under the combined action of bending and torsion, the factors of effect on the capacity were also analyzed. The formula about the cracking torque and marginal tor- sional moment are presented. The results are in good agreement with the measured ones.
