摘要
为确保筒仓-散体结构体系的长期安全储备和运行,从散体参与地震响应的有效质量、散体与仓体的相互作用、地震作用下筒仓结构的力学特性三个方面系统地归纳总结了筒仓-散体结构体系的抗震研究发展历程和现状。并结合隔震减振技术在筒仓-散体结构体系的研究现状,指出进一步精确并系统确定地震作用下筒仓内部散体参与振动的有效质量应是今后研究的重点,建议加快推进筒仓-散体结构体系抗震减振研究,建立适用于筒仓-散体结构体系的隔震减振理论体系,并对其发展趋势和方向进行展望。
In order to ensure the long-term safety storage and running of the silo-bulk material system,the development process and current status of silo-bulk material system were summarized and analyzed,from the aspects of effective mass of the content in the earthquake,the interaction effect between the silo wall and bulk solid,the mechanics characteristics of silo under the seismic.Base on the research of isolation and vibration reduction techniques for silo-bulk material system,the study on precise and systematic division of effective mass participation coefficients of silo-bulk material system under earthquake response should be focused at present.In order to increase the aseismic behavior of silo structure,the application of this technology in the field of silo structures should be enhanced and a theoretical system of isolation and vibration reduction suitable for silo structures should be established.At last,the development trend on dynamic performance of silo structure was also predicted.
