There exists a large amount of data indicating that a reduction of strength in a soil takes place but that the amount of this reduction is limited. On the other hand some authors claim that such a reduction is not possible because the ultimate undrained shear strength of a given saturated soil depends only on its void ratio and structure. In this paper it is attempted to bring some clarification to this conflict and in doing so the Critical State Model is employed. Fifty-eight dynamic and nine static triaxial tests have been conducted on samples consolidated from a water content twice the liquid limit to different consolidation pressures. The soil used in experiments is ‘Arnavutköy Kaolini’ with a liquid limit of <em>w</em><sub><em>L</em></sub> = 65% and plastic limit <em>w</em><sub><em>P</em></sub> = 30%. The results of the present series of tests indicate that the main effect of dynamic loading is on the increase of the pore water pressure which in turn causes the soil to behave like an overconsolidated soil. Previous research has shown that the void ratio of an overconsolidated soil sample decreases at the shear zone during shearing. All the results expressed above, as well as the results of tests conducted during this research, indicate that a reduction in the shear strength occurs in a normally consolidated clayey soil due to the repeated loading application.</p></div>","PeriodicalId":100715,"journal":{"name":"International Journal of Soil Dynamics and Earthquake Engineering","volume":"3 4","pages":"Pages 184-190"},"PeriodicalIF":0.0,"publicationDate":"1984-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0261-7277(84)90034-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74488782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trivial modifications are also proposed to the standard scheme that would enable the researcher to study the amplification or deconvolution of non-vertically incident <em>SH</em> waves with a code like SHAKE.

Since the foundation motion is effected not only by the kinematic interaction but also by the dynamic interaction of a soil-foundation system, a general deconvolution method between the kinematic interaction and the dynamic interaction of a soil-foundation system based on the observed data is derived in this paper, where a structure is modelled by a multiple-degree-of-freedom (MDOF) system which represents the dynamic interaction, and the unknown foundation input motion is expressed by a moving average model (MA-model) of the ground motion, which represents the filtering effect of kinematic interaction. Generally, as the parameters of a MDOF system can not be determined exactly, these parameters are treated as random variables on trial using the Monte Carlo simulation method. Next, the coefficients of the MA-model are identified applying the Kalman filter. On the many trials, the result which minimizes the root-mean-square error between the observed response and calculated response is determined as the best estimation. Examples of (1) two single-degree-of-freedom systems arranged in a series and (2) a four-storey reinforced concrete school building are demonstrated to verify the proposed method.</p></div>","PeriodicalId":100715,"journal":{"name":"International Journal of Soil Dynamics and Earthquake Engineering","volume":"3 3","pages":"Pages 157-164"},"PeriodicalIF":0.0,"publicationDate":"1984-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0261-7277(84)90046-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78320138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
