Abstract

Even in today's computer-oriented world with all its sophisticated analysis tools, engineering judgement is required to assess the adequacy of computer output. Approximate analysis method can be a feasible tool to check solutions from computer softwares roughly. It can be a simple tool for structural engineer to check force distribution in frame. Also, it can serve as a basis in selecting preliminary member sizes. The objective of this study is length factor and inflection points. The validity of this method is examined by comparing the results of this method with those of existing methods, showing improvement in the prediction of structural behavior.

오늘날 컴퓨터가 복잡한 해석을 수행하는 도구로 이용되더라도 해석의 결과값에 대한 적합성을 평가하기 위해서는 공학적 판단이 필요하다. 근사해석법은 이러한 결과값을 검토하기 위한 편리한 도구가 될 수 있으며 골조의 응력분포 그리고 부재 사이즈의 직하중 및 수평하중을 받는 강접골조를 근사해석하기 위한 방법을 제시하는 것이며 본 연구에서 제안한 방법의 유효성을 검증하기 위해서 기존의 방법과 비교하였고 구조물 거동의 예측에 있어서 향상된 결과를 보여주었다.
