Composite Grid Reinforcement Concrete Columns

小行星9632850 用于混凝土的钢筋遭受有限的抗腐蚀性、昂贵的现场组装和在严重地震下缺乏延展性。 复合材料具有出色的耐腐蚀性和耐疲劳性，重量仅为钢的1/5。 石墨纤维/有机基单向复合材料具有优异的纵向刚度超过20，000 ksi，抗拉强度超过200 ksi，如果设计得当，可以直接与钢筋竞争。 因此，本提案的目标是展示和开发： 一种新型复合材料格栅的制造方法 加固. 加固系统的工厂/现场快速组装。 柱用网格加强型围护蒙皮。 在静态、动态和动态载荷作用下， 循环荷载

9632850 Tsai Steel reinforcing bars for concrete suffer from limited resistance to corrosion, costly field assembly and lack of ductility under severe earthquake. Composite materials have outstanding corrosion and fatigue resistance and a weight 1/5 of steel. Graphite fiber/organic matrix unidirectional composite materials have outstanding longitudinal stiffness over 20,000ksi and tensile strength over 200ksi, and when properly designed can compete directly with steel rebars. It is therefore the goal of this proposal to demonstrate and develop: A novel manufacturing method of composite grid reinforcement. Rapid factory/field assembly of reinforcing system. Grid reinforced containment skin for columns. Test data on columns subjected to static, dynamic and cyclic loads.
