위상 및 크기 최적화를 고려한 대공간 철골트러스 구조물의 형상결정 방안

It is very important to find out the initial shape for the efficient design of spatial steel truss structure. Also, the reasonable optimization techniques are required in order to perform the optimal design of the structure. Traditionally, the structural design process starts with an initial conceptual model which is inspired by the designer's intuition and previous experiences. So, this study is to provide the information about the optimum layout of structure through the integrated process for the initial topology and final size optimization. To this end, this study finds out the initial optimum layout of spatial steel truss structure by using the topology optimization for unit structure model, and then decides the final optimal shape by using the size optimization for the total structure combined with several unit models.
