指數衰變律
英文
exponential decay law-
It is indicated in the test that the influence of loading to strain in the grout was about in the range of 5 ~ 6m, and very weak beyond 4m. the distributions of strain and bond stress in the grout are attenuated in the minus exponential rule
試驗結果表明,加載對錨固段內的應變影響范圍大致在5 6m左右, 4m以外很微弱;錨固段注漿體內的應變與粘結應力分佈按照負指數規律衰減。The change of dynamic pressure in the orientation of wave spreading follows the damping of e - index 6
5 、堤心內沿波浪傳播方向變化的動壓遵循e指數衰減規律。Subsequently, the waves induced forces and their driven effects on currents are studied in detail. in the discussion of the effects of currents on waves, according to the wave radiation theory and the law of wave action conservation, the equivalence of none vorticity condition of the vector of wave number in constant wave field and fermat theory is testified. the dynamic and kinematics effects of background currents on waves are introduced concisely
在流對浪的作用討論中,依據波動的射線理論和由變分原理導出的波作用量守恆定律,闡明了穩定波場波數矢量的無旋條件與費馬原理的等價性,扼要討論了背景流場影響海浪的運動學效應和動力學效應,首次指出水位(包括天文潮位與風暴潮位)變化對海浪成長與消衰的影響,為流浪潮聯合數值模式的發展提供必要的理論依據。The resistance attenuation of each element is considered in the design process, and the statistical parameters of the elements are assumed to be the same as the investigated results of china. in the process of the calculating of the element reliability attenuation in expected service life, several load combination and different load ratio of dead load to live load are considered. in order to ensure that structure reliability in expected service life satisfies the requirement of today ’ s code, a method of choosing the initial reliability index of structure basing on the length of expected service life and the structure resistance attenuation is proposed and the corresponding durability reduction factor is chosen by an optimum algorithm
根據我國現行建築結構可靠度設計原理,考慮耐久性退化影響因素,設計了抗力統計參數與我國調查結果一致的五種代表性鋼筋混凝土構件,考慮多種荷載效應組合以及不同荷載效應比,研究了不同使用期內代表性構件的可靠度變化規律;為保證預期使用期內結構可靠度水平仍可滿足現行規范要求,提出了根據預期使用期和抗力衰減幅度確定結構設計可靠度指標的方法,並通過優化的方法確定了預期使用期內的耐久性折減系數,給出了預期使用期結構可靠度設計的實用設計方法。分享友人
