静载下碱式硫酸镁水泥混凝土梁抗弯性能退化的数值模拟研究
Numerical simulation of the degradation in bending behavior of basic magnesium sulfate concrete beam under static loading
摘要
Abstract
Basic magnesium sulfate cement(BMS)offers several advantages,such as fast setting,high tensile strength,and resistance to water and corrosion.However,the performance of high-strength BMS beams has yet to be fully explored.A numerical simulation was conducted to study the degradation of the bending performance of BMS concrete beams with a compressive strength of 50 MPa under static loading.The study focused on analyzing the beam's bearing capacity,deformation,and other mechanical properties.The results demonstrate that the failure process of BMS concrete beams can be simulated accurately using Ansys,provided that the partial tensile capacity of the cracked BMS concrete in the tensile zone of the beam is considered.A higher reinforcement ratio of BMS concrete beams leads to greater ultimate bearing capacity.However,as the reinforcement ratio increases,the flex-ural bearing capacity of the beams approaches a consistent value.Parameter sensitivity analysis reveals that increas-ing the section height of the BMS concrete beam contributes more to the increase in bending moment than other fac-tors.This study holds considerable significance for the application of BMS concrete in construction projects.关键词
