Research Of Shaking Table Testof Seismic Response Of Enclosure Walls To Multi-functional Vibration-absorption Structure

The earthquake is a serious sudden natural disasters, It cause a huge economic losses and far-reaching influence in society, Because of the earthquake is random and complexity and the severity of the damage, The human face earthquake disaster when compared to the other disaster are more difficult to resist. In the earthquake disaster in front, human beings have to face how to make the building structure more safe and reliable,This is building structural engineer to continuously pursue dreams. So the damping control be applied in architecture is constantly presented and innovative researche in recent years.On the basis of previous studies, enclosure walls to multi-functional vibration-absorption structure (EWMVS) masterly is used the enclosure wall as as the important component of tuned mass damper, neither need additional mass block and under the action of minor earthquakes to increase the stiffness of the structure, with tuned mass damper and damping vibration double effect.Based on the structure vibration control and optimization design theory,the1/3scale EWMVS model are tested on shaking table and carried on the performance of the seismic response analysis and shock abortion. Related research content and conclusions are as follows:1.The concept of vibration control, classification, principle are presented, the vibration control development course, passive damping control present situation of the study are, summarized. The passive control structure the practical application of the technology are presented.Based on this, the the superiority of, working principle, and of the existing research results of enclosure walls to multi-functional vibration-absorption structure (EWMVS) were introduced.2. The working principle of the TMD is briefly described, on the basis of theTMD work principle of got the work principle of MTMD, optimization method and shock absorbing the influencing factors,at last for the third chapter laid a solid theoretical basis.3. Common seismic frame structure and enclosure walls to multi-functional vibration-absorption structure (EWMVS) model shaking table test results are compared each other analysis, analyzes the damped effecs of EWMVS and the general rule of existence.4. In order to verify the enclosure walls to multi-functional vibration-absorption structure EWMVS damping effect of test, EWMVS model was set up in SAP2000general software,(EWMVS) numerical simulation shock absorption effect is analyzed, finally the numerical simulation results and experimental results are compared and analyzed.Enclosure walls to multi-functional vibration-absorption structure (EWMVS) seismic response theory is analyzed in this paper, through the earthquake simulation shaking table test the shock absorption effect,the influence factors and the shock absorption rule of EWMVS are analyzed, Based on the test results EWMVS numerical simulation results and experimental results are comparison analyzed.Research shows that structure of earthquake hazards can be EWMVS control, EWMVS can be used in multistory buildings, high buildingand strengthening old buildings. Therefore, enclosure walls to multi-functional vibration-absorption structure (EWMVS)must have a broad development prospects.
