铅芯橡胶支座的双线型模型研究
|
摘要
对双线型恢复力模型刚度拐点的判断,提出了简单的两步判断法,并根据这一刚度判断方法,编制了可控精度的Wilsonθ法程序.文章还研究了双线型模型在简谐荷载和地震荷载作用下的等效线性化方法,同时提出了在地震作用下峰值等效的两点等效方法.
About the determination of stiffness inflection point in bilinear restoring force model, the article puts forward a simple two-step discriminate method. It can work out the Wilson program which can be controlled at precision. It also researches equivalent linear method of bilinear mode under the acting of simple harmonic load and earthquake load. It puts forward two-point equivalence method which is peak equivalent in earthquake.
