摘要
目前众多原设计为钢筋混凝土结构的房屋,因使用功能或建筑外形的改变,需在原混凝土结构中增加型钢,新增的型钢与原结构存在较多冲突之处。以不影响原设计结构抗弯、抗剪承载力为原则,通过优化钢筋形式、型钢开孔后补强、增加搭筋板等方式对节点进行优化设计。经过理论测算,优化后的节点能达到设计强度要求。
At present,many buildings that original design is reinforced concrete structure,due to the change of function or architectural appearance,are necessary to increase the structural steel in the original concrete structure. There are many conflicts between the new structural steel and the original structure,so as not to affect the original design structure bending and bearing capacity. The design of the joints are optimized by optimizing the form of reinforcing bar,strengthening after opening structural steel and adding reinforced plate. After the theoretical calculation,the optimized joint reaches the requirement of designed strength.
