Reinforced concrete structure has very sensitive behaviour with the impact of seawater content. This work will describe about the effect of seawater content on the shear strength of reinforced concrete beams. Previous research focused on studying effect of seawater content on compression strength, tensile strength, flexure strength, and bond strength in concrete. A review of shear failures conducted by previous researchers without getting an effect on seawater content attacks. Reinforced concrete beam has measure on 1000200400 mm. Seawater content attack is given during the treatment process of reinforced concrete beams. Control testing is carry out by treating on fresh water. Stages of testing include testing the basic materials of concrete, immersion in sea water or fresh water, compression strength testing with cylindrical specimens on concrete age 28 and 90 days, as well as shear strength testing. Therefore, the aggressive nature of seawater which can cause micro crack in concrete pores, so that the shear strength that treated using sea water for 90 days has decreased by 10.70% from treatment using fresh water. The decrease in strength that occurs in the shear strength of reinforced concrete beams is not recommended in planning because it can risk to construction.

钢筋混凝土结构对海水含量的影响具有非常敏感的行为。这项工作将描述海水含量对钢筋混凝土梁抗剪强度的影响。以前的研究集中在研究海水含量对混凝土的抗压强度、抗拉强度、抗弯强度和粘结强度的影响。以前的研究人员对剪切破坏进行的审查，但对海水含量攻击没有影响。钢筋混凝土梁的尺寸为 1000200400 毫米。在钢筋混凝土梁的处理过程中会出现海水含量的攻击。通过对淡水进行处理来进行控制测试。测试阶段包括测试混凝土的基本材料，浸泡在海水或淡水中，对 28 天和 90 天混凝土年龄的圆柱形试样进行抗压强度测试，以及剪切强度测试。因此，海水的侵蚀性会导致混凝土孔隙产生微裂缝，使海水处理 90 天后的抗剪强度比淡水处理降低了 10.70%。不建议在规划中建议钢筋混凝土梁的抗剪强度出现强度下降，因为这可能会给施工带来风险。
