The paper reports on the development of a single-story, single-bay portal frame model as part of the AIMS2 （attract, inspire, mentor and support students） grant supported through the US DOE （Department of Education） summer research program at California State University, Northridge. This research effort is part of a comprehensive program to develop laboratory models of structures commonly encountered in civil engineering practice, which can serve the dual purpose of accomplishing engineering education and research in the areas of structural and earthquake engineering. The objective of the present study was to construct a physical model of the aforementioned frame to experimentally collect data due to the application of vertical and lateral loadings through instrumentation such as strain gages and an LVDT （linear variable differential transformer） displacement transducer, and also to make comparisons with theoretical and numerical predictions.展开更多

Some people assert that paper-based media will come to an end. However, the author believes that the paper media will not come to an end under the media convergence trend. It will develop parallel with media integration. The reason why the author has this view is that, on one hand, paper-based media has its unique physical characteristics. In the real world, paper media brought us the aesthetic experience by ＂five senses＂ . It cannot be replaced by the media convergence. The paper media will also make survival steering dimension; on the other hand, cultural heritage of the paper media make itself a unique appreciation of the value and not transcendent. Therefore, the paper media in the media convergence trend will continue to exist and turned to be ＂concept book＂ that admiring is the main part and reading supplemented.展开更多
