Standards in our country is prepared for decades a large number of structural system , light steel structure residential system previously in our country are technical gaps , so can not meet certain provisions of peremptory norms . Recently, a joint venture between Chinese and Canadian Qingdao the Mai Wah extremely Steel Residential Development Co., Ltd. , named the \. This topic is to delineate the scope of the security of the resonance region do light steel houses shaking table test to study its dynamic characteristics and seismic capacity , such as natural frequency , makes external stimulus away from the resonance region ( beyond the 25% range ) , and isolation and to take certain measures to eliminate vibration damping effect . In this issue , by using the finite element program (ANSYS) simulation analysis , and to compare this calculation and test structure , to improve the design of this structure . Of this research work is mainly the following aspects : 1 , on the basis of extensive search of the literature , summarizes and comments extremely dynamic characteristics of the steel structure system theory analysis and experimental research , analyze the problems in the field of research . The immense steel structure system housing model by the ratio of the two layers of full scale modal analysis , to understand the dynamic characteristics of the system ( vibration type , period and damping ) ; model shaking table test , revealing the seismic response of the system ( displacement, velocity , acceleration, etc.) law . With ANSYS to establish a three-dimensional finite element model of the steel structures housing , dynamic characteristics analysis and calculation of the input EI-Centro wave , the seismic response of relocation aha , this article from the EI-Centro wave . 4 , through a comparative analysis of the results of the model shaking table test results and analysis of finite element simulation , verify the reasonableness of the calculation model , and the results are in-depth analysis , useful conclusions as to further improve the existing seismic design of buildings \GB50011-2001) for provisions and provisions stating provides theoretical support and test data , and provide a valuable reference for designers . Finally, on the basis of a comprehensive summary of this work , this topic requires further study asked Hao .
