摘要
针对结构抗震减震隔震设计结构动力学基本方程,进行了基本结构刚度、阻尼和质量三方面减震隔震设计问题特征分析,专门指出刚度和阻尼的减震隔震设计研究已经有规范规定,但对减轻结构质量的减震隔震设计仍是需要深入研究的创新问题。目前采用新材料进行设施农业结构减震隔震设计,特别是采用玄筋混凝土现代无金属结构进行结构抗震减震隔震设计,结构最优化设计的实现便有了新契机,且容易实现抗力均匀分布,将较为彻底地解决地震工程的最优结构抗震问题。
The analyses on the characteristics of the three parameters,the basic structural stiffness,damping and mass in the structural dynamics equations of the seismic design were carried out.It is emphasized that although the research on the design of damping and seismic isolation has been given in the regulations,the design of damping and seismic isolation with reduced structural mass is still an innovative issue that requires in-depth research.The use of new materials for the seismic isolation design of facility agricultural structures,especially the use of mysterious reinforcement structures,meets new opportunities to realize the optimal design of structures,and facilitates the uniform distribution of the resistance,which will provide a relatively complete solution to the optimal design of the seismic structures in the field of the earthquake engineering.
