- Abstract
- Modular sub-structures consist of standardized concrete-filled tube (CFT) column members and their connections. Generally, the plastic stress block concept is widely used to calculate the strength of CFT section. However, it is difficult to evaluate the flexural strength with the plastic stress block concept consisting of multiple columns due to difficulty to define plastic neutral axis. In this paper, plastic hinge analysis was suggested to evaluate the flexural strength.
모듈러 하부구조는 표준화 된 CFT 기둥 모듈로 구성된다. 일반적으로 CFT 단면의 설계에는 소성응력 블록방식을 이용하여 설계한다. 하지만, 다주식 CFT 교각의 경우 각각의 기둥에 인장과 압축이발생하여 소성응력 방식을 적용하는 것은 어렵다. 이 논문에서는 소성해석 방식을 적용한 CFT교각의설계 방법을 제시하였다.
