关于结构分割转换工法不同分割方式的探讨

为研究结构分割转换工法（CC工法）中不同结构分割方式对设计、施工的影响，丰富CC工法的相关研究，首先对CC工法跨中设缝和柱顶设缝2种典型分割方式相应的结构体系、受力特性进行分析和比较，并采用数值分析的方法，研究2种分割方式下不同节点位置和节点性质对结构受力的影响。然后对施工环节2种不同分割方式施工步序、节点施工质量控制、经济状况进行分析比较。结果表明： 1）柱顶设缝时，节点的设计、施工较为困难，施工措施费较高； 2）跨中设缝时，节点处理较为简单，经济优势较为突出，但跨中节点的性质在设计时较难把握，宜视构造特点具体考虑。

Structure Division Methods of Structural Cut and Convert Method

In order to study the influence of structural cut and convert (CC) method on design and construction under different structure division methods, and rich the relevant research of CC method, the structural system and mechanical properties corresponding to two different structure division methods, i.e. joint in mid span and joint on column top, are analyzed and compared; and furthermore, the influence of the joint positions and properties of the two structure division methods on the structure are numerically analyzed. And then comparison is made between the two structure division methods in terms of construction sequence, joint construction quality control and economic indicators. The research results show that: (1) When the joint is set on column top, the design and construction are difficult and the construction cost is high. (2) When the joint is set in mid span, the design and construction are applicable, whereas the properties of joint is difficult to control, which should be considered cautiously. 
