RESEARCH INTO EFFECT OF CONCRETE STRENGTH DEFICIENCY ON STRUCTURAL BEHAVIOR
-
摘要: 从钢筋混凝土结构设计理论出发,研究了混凝土强度不足对各种不同类型结构构件承载能力、截面裂缝宽度及结构耐久性的影响,并提出了相应的处理办法,供钢筋混凝土结构设计施工、可靠性检测和加固改造参考。Abstract: Based on the reinforced concrete structure design theories, the effect of concrete strength deficiency on the bearing capacity, crack width and structural durability of different sorts of structural members is studied, and some relative measures are also put forward to treat the concrete strength deficiency, which may be used as a basis for the design and construction, and for the reliability appraisal and strengthening reconstruction of reinforced concrete structures.
