摘要

采用MIDAS有限元软件对无粗骨料钢纤维混凝土梁的抗剪强度进行了数值计算。采用全应变裂纹模型对钢纤维混凝土梁进行建模,并对其压缩性能和脆性拉伸性能采用Thorenfeldt模型。采用修正的fib黏结应力-滑移函数来模拟混凝土与钢筋之间的黏结。从有限元分析来看,无粗骨料的钢纤维混凝土梁的开裂形态和破坏时的最大荷载与试验结果相似。当纵向配筋率大于3%时,有限元分析开始高估最大荷载。分析和试验结果表明,当配筋率为7.82%时,最大荷载比为136%。纵向配筋率对无粗骨料SFRC抗剪强度的影响小于ACI 318-19预测的标准强度混凝土。不含粗骨料的SFRC粘结应力-滑移关系有待进一步研究。

Shear Strength of SFRC Beams Without Coarse Aggregate Using Finite Element Analysis with Bond-Slip
The numerical evaluation of the shear strength of Steel-Fiber Reinforced Concrete (SFRC) beams without coarse aggregate using data from previous research has been performed in MIDAS FEA. The SFRC beams are modeled by using the total strain crack model with Thorenfeldt for compression behavior and brittle tension behavior. Modified bond stress-slip functions proposed by fib have been used to model the bond between concrete and reinforcement. From the finite element analysis, the cracking pattern and the maximum load at failure of SFRC beams without coarse aggregate have been similar to the test results. As the longitudinal reinforcement ratio increases above 3%, the finite element analysis starts to give overestimated maximum load. The highest ratio of maximum load from analysis and test results equal to 136% has been obtained from 7.82% reinforcement. It is also observed that the influence of longitudinal reinforcement ratio on the shear strength of SFRC without coarse aggregate is lower compared to normal-strength concrete predicted by ACI 318-19. Further studies on bond stress-slip relationship of SFRC without coarse aggregate are needed.

期刊介绍: The International Review of Civil Engineering (IRECE) is a peer-reviewed journal that publishes original theoretical papers, applied papers, review papers and case studies on all fields of civil engineering. The scope of the Journal encompasses, but is not restricted to the following areas: infrastructure engineering; transportation engineering; structural engineering (buildings innovative structures environmentally responsive structures bridges stadiums commercial and public buildings, transmission towers, television and telecommunication masts, cooling towers, plates and shells, suspension structures, smart structures, nuclear reactors, dams, pressure vessels, pipelines, tunnels and so on); earthquake, hazards, structural dynamics, risks and mitigation engineering; environmental engineering; structure-fluid-soil interaction; wind engineering; fire engineering; multi-scale analysis; constitutive modeling and experimental testing; construction materials; composite materials in engineering structures (use, theoretical analysis and fabrication techniques); novel computational modeling techniques; engineering economics. The Editorial policy is to maintain a reasonable balance between papers regarding different research areas so that the Journal will be useful to all interested scientific groups.
