碩士 === 國立中興大學 === 土木工程學系所 === 98 === The design strength of concrete-filled tubes (CFT) is being investigated and evaluated based on the current methods as specified in the AISC specifications. The AISC Specification applies the steel column formulas with the use of coefficients for transforming the concrete into steel to determine the CFT design strength. In AISC-2005, the design strength of CFT is being evaluated through the use of two approaches including the plastic stress distribution and strain compatibility methods. This study used both the plastic stress distribution and strain compatibility methods to calculate the design strength of CFT, and compare the design strengths using these two methods. The calculation is proceeded with the numerical approach by using the developed software program and the P-M curves are plot. The P-M curves are plot for both the rectangular and square sections. The illustrated examples are furnished to demonstrate the step-by-step procedure to obtain the CFT design strength based the AISC Specification.
