The purpose of this paper is to evaluate the structural performance of joints between modules with steel plate press forming type non-symmetric cross section. The main experimental variables are direction of load, whether vertical bolts are fastened, and whether the concrete inside the column is filled. A total of three experiments were performed for each variable. Experimental results show that the behavior of the joints dominated by the local buckling deformation of the upper and lower beam flanges of the module joints, and the final failure was the fracture of the column-beam welds. In case of short side direction, it is possible to secure the performance of intermediate moment frame (0.02 rad). In case of long side direction, it is evaluated that the performance of special moment frame (0.04 rad) is secured regardless of whether or not concrete is infilled in the column.

Membrane-based gas separation is one of the next generations’ gas separation technology for various gas and chemical industries (e.g. air separation, H2, CO2 separation, hydrocarbons, and fluorinated gas separation, etc). Membrane has the advantages of i) low energy consumption without a phase change during the separation, ii) small footprint and easy scale-up of membrane modules, and iii) clean process without any emission of harmful byproducts. Membrane materials are mostly composed of polymeric, inorganic and metallic materials whereas membrane modules are fabricates as flat-sheet, plate-and-frame, spiral-wound and hollow fibers. In this presentation, the evaluation method of membrane materials and modules for gas separation applications will be discussed.

Seismic performance evaluation of existing building usually needs much time and man power, especially in case of nonlinear analysis. Many data interaction steps for model transfer are needed and engineers should spend much time with simple works like data entry. Those time-consuming steps could be reduced by applying computerized and automated modules. In this study, computational platform for seismic performance evaluation was made with several computerized modules. StrAuto and floor load transfer module offers a path that can transfer most linear model data to nonlinear analysis model so that engineers can avoid a lot of repetitive work for input information for the nonlinear analysis model. And the new nonlinear property generator also helps to get the nonlinear data easily by importing data from structural design program. To evaluate the effect of developed modules on each stages, seismic performance evaluation of example building was carried out and the lead time was used for the quantitative evaluation.

해체 작업은 최적의 해체시나리오에 따라 경제적이면서 안전하게 수행되어야 하기 때문에 제염해체의 계획단계에서 시나리오의 다양한 관점에서의 평가는 매우 중요하다. 따라서 사전에 해체 시나리오에 대한 평가자료를 산출하기 위한 평가모듈개발이 필요하였다. 본 논문에서는 해체 시나리오의 전체적인 과정을 컴퓨터 가상공간에서 표현하여 해체과정을 이해하고 문제점을 파악하기 위해 디지털 목업 시스템을 구축하였다. 그리고 해체일정과 예상비용을 산출하기 위해 해체작업시간 및 예상비용 산출식을 도출하였다. 그리고 대상물의 방사화 정도를 쉽게 파악하기 위하여 방사화 가시화 모듈을 개발하였다. 마지막으로 전체적인 결과와 다른 여러 중요요소를 기초로 하여 해체 시나리오를 평가하는 방법론에 대해 기술하였다.
