In our country, the worked-out standard criterion mainly aims at those structural system which have been greatly used for decades, new type of light gauge steel structure residential system is still a technical blankness in our country now, so it cannot fulfill certain items in imperative criterion being used now.Not long ago, a brand-new construction system named websteel environment -protecting residence which is exploited by Qingdao maihua websteel structure residential exploitation Ltd., a joint venture financed by China and Canada. This websteel system have passed result evaluation masterminded by the science and technology developmental promotion center of ministry of construction. This study research the dynamic characteristic and aseismatic ability of the light steel structural building by means of earthquake simulation vibratory platform experimentation, line out the safe area of syntonic sections in order to make exterior promptings away from those syntonic sections(beyong 25%), and we also take several kinds of vibration insulation steps to eliminate and reduce vibration. In this study, we put emulational analysis research into practice via finite element program(ANSYS), and compare this calculating structure with experimental structure, so as to improve design of this structure.The textual research work mostly includes several aspects below:1, On the basis of searching literature inside and outside China abroadly, summarize and review academic analysis of the websteel structural system's dynamic characteristic and experimental research results, analyze the problems existing in that research field.2, We get its dynamic characteristic(vibration model, cycle and damp) through the mode analysis of exact proportional two-floor websteel structuralbuilding model; and also its earthquake reaction(displacement> speed and acceleration) rules through model vibratory platform experimentation.3^ Creat the three-dimensional finite element model of websteel structural building using ANSYS for the purpose of dynamic characteristic analysis, calculate the earthquake reaction when El-Centro wave and qian'an wave are inputed, this text mainly based on El-Centro wave.4> We validate the rationality of calculating model through the contrast analysis between model vibratory platform experimental outcome and finite element simulation analytical outcome, moreover, analyze the calculating outcome thoroughly to get some instructive conclusion. Our work can provide academic sustainment and experimental data for ulteriorly perfecting some items and its explanations of the (Architectural Aseismatic Designing Criterion? (GB50011 — 2001), it can also offer valuable reference for designing personnels.At last, the text advances several problems about this study needed a further research based on summarizing our work roundly.
