Abstract
강합성 구조물의 설계절차는 파형강판구조물에 대한 현행 국내외 시방기준을 따르고 있는데, 시방기준이 2차원 해석 및 설계를 바탕으로 규정되어 있기 때문에 비등가 단면인 강합성 빔보강 공법에는 현행 시방기준을 적용할 수 없다. 그러므로 등가단면의 구조물로 환산하여 2차원 해석 및 설계를 수행하게 된다. 그러나 강합성 빔보강 공법은 종방향을 따라 일정한 간격을 두고 빔과 타입콘크리트를 이용하여 보강을 한 형태이기 때문에 3차원 해석에 기초한 설계과정이 요구된다. 따라서 본 연구에서는 수치해석을 통해 3차원 설계를 위한 해석적인 근거를 제시하고자 한다.
In case of the design method, which is used in the inside and outside of the country, on corrugated multi plate structures, section modulus would be determined by assuming 2-dementioanl equivalent section of those structures. However, it is impossible to consider 3-dimentional effects when 2-dimentional design method is applied since structures are reinforced with a pattern of the 1200, 1600 mm reinforcements except the 800 mm reinforcement. Thus, in this study, technical specification standard is analyzed for the existing corrugated multi plate design methods, and section strengths, moments, and so on of equivalent and practical sections are compared and estimated using 3-dimentional FEM (finite element method) for semicircles and architectural features widely used. Based on the results of that analysis, analytical basis for 3-dimentional design of the CBS-RIB is suggested.
