| Along with the continuous progress of the society,the rapid development of science technology and the improvement of human's living standards,equipment-structure composite system become a common form of modern buildings.When subjected to earthquake,there is often a complex dynamic interaction in the composite system.Currently,the theoretical analysis and research of equipment-structure dynamic interaction system main stay in linear phase and base on rigid foundation assumptions.Without taking the non-linearity of equipment and structure the effects of soil-structure interaction into consideration,the current system works differently from the actually engineering structure.Therefore,this article rises a equipment-structure dynamic interaction model,which is made of steel,to calculate and analysis using dynamic time history analysis method.The main contents and research results are as follow:1.From the aspects of the design and production of test models,test equipment,test load system and test data collection,the paper carry out a detailed test program design depart on the forthcoming shaking table tests.2.Based on the rigid foundation assumption,the paper analyze the impacts of the equipment-structure dynamic interaction on equipment and structure under different earthquake phrases.After taking equipment-structure dynamic interaction into consideration,the seismic response of equipment and structure are obviously different from without considering the dynamic interaction.3.Taking SSI into consideration,the paper analyze the impacts of the equipment-structure dynamic interaction on equipment and structure under different earthquake phrases,which is used to be compared with the conclusions based on the rigid foundation assumption.After taking SSI into consideration,the impacts of the equipment-structure dynamic interaction on equipment and structure are obviously different from the circumstances when based on rigid foundation assumption. |
