摘　　要：传统混凝土由于存在抗压强度低、耐久性差等缺点,不能很好的满足当前高层、超高层、大跨度等实际工程对其力学性能的要求。目前,国内外研究者已经广泛研究了高强混凝土的基本力学性能,高强混凝土梁、柱以及节点的受力和抗震性能。对高强混凝土基本力学性能及高强混凝土构件的力学性能研究进展进行了归纳总结,分析了剪跨比、轴压比等参数对高强混凝土构件受力性能的影响;对高强钢筋与高强混凝土制成的双高强材料构件力学性能进行了总结;对高强混凝土构件的延性等变形性能的影响因素进行了分析探讨;从不同角度对比分析了现有高强混凝土梁抗剪承载力计算理论和设计方法。基于现有研究成果,指出了目前高强混凝土研究中存在的不足,并对今后研究的发展趋势进行了展望。The traditional concrete has the shortcomings such as low compressive strength,poor durability,and so on.So it cannot meet the needs of the high-rise buildings,large span buildings and the actual engineering structures.At present,domestic and foreign researchers have studied the basic mechanical properties of high-strength concrete and the mechanical properties of high-strength concrete members extensively.The research about the basic mechanical properties of highstrength concrete and the mechanical properties of high-strength concrete members were summarized.The basic mechanical properties of high-strength concrete,the mechanical and seismic properties of high-strength concrete beams,columns and joints were analyzed in detail,and the shear-span ratio and axial-load ratio were discussed.The mechanical properties of high-strength reinforcement and high-strength concrete dual high strength material members were summarized.The influence factors of ductility and other deformation properties of high-strength concrete members were studied and researched.Compared and analyzed the existing calculation theory and design method for the shear capacity of high-strength concrete beams from different angles.Based on the existing research results,the deficiencies of the current research of high-strength concrete were pointed out,and the development trend of the research in the future had prospected.
