建筑结构工程在抗震设计中的探索
|
摘要
建筑结构工程抗震的设计,起着消耗地震能量的主要作用,通常把"小震不坏、中震可修、大震不倒"作为建筑抗震设计的基本准则。分析指出,在建筑结构工程抗震问题上不能完全依赖计算设计,应立足于工程抗震基本理论及长期工程抗震经验总结。由于抗震的复杂性,一般通过定性的实际现象、解释物理机制、推断变化过程、总结特性规律和分析灾变后果来解决,在此基础上,结合对建筑结构抗震技术的基本认识、基本分析和建筑结构抗震工程的原理,使用SME智能合金材料隔震并吸收和消耗地震输入能量,以达到减小结构振动和地震破坏的目的。拟对我国现行规范的相关规定提出修正建议,对抗震设计方法进行初步的分析。
It consumes energy and plays a major role of engineering seismic design of building structure.Seismic design of building structure takes "No damage in minor earthquake,repairable under moderate earthquake,no collapse under great earthquake" as the basic criteria for seismic design of buildings.On the structural engineering seismic problems should not depend solely on calculated design,should base on the basic theory of engineering seismic and seismic behavior of long experience.Because of the complexity resists the earthquakes,the questions are solved through the qualitative actual phenomenon generally,the explanation physics mechanism,the inference of change process,the summary characteristic rule and the analysis cataclysm consequence.On this basis,combining with the basic understanding of seismic technology,the basic principles of analysis and seismic engineering,it is used of the SME smart alloy materials and earthquake input energy consumption isolation and absorption to achieve the purpose of reduce structural vibration and earthquake damage.Some advice have been given for current norms and the seismic design method.
