This article presents a statistical study on strength reduction factors for seismic-isolated bridges in far-fault areas. 1410 ground motions are selected and modified to be compatible with the recommended response spectra. Then, they are divided into 60 groups to investigate the effects of PGA/PGV ratios, soil conditions and post-to-pre-yield stiffness ratio. Results show that reduction factors are significantly affected by the PGA/PGV ratio, while the latter two items are not as important as the first one. Finally, an improved equation to estimate the reduction factor is proposed, and the accuracy of the equation is verified by additional records.  相似文献

Because of the significance attached to it, the Knesset passed the 1950 Law of Return in an unprecedentedly short time, but it took two more years to pass the Citizenship Law. The official protocols regarding the legislation of Israel’s Citizenship Law illuminate the main concerns of the drafters. The goal of the emerging national citizenship regime was not just to promote Jewish immigration but to establish a modern state that prohibited dual citizenship, accepted naturalizations, prevented statelessness, and granted equal citizenship to women. These policies are accumulations of countless opinions, values, interests, and ideas, each with different conceptions of citizenship and nationhood.  相似文献

The account of the reign of Amaziah in 2 Chronicles 25 is a true house of treasures for those studying the book of Chronicles in its historical milieu or reconstructing the intellectual milieu of ancient Yehud. In particular, this study shows how 2 Chronicles 25 calls attention and sheds light on: (1) matters of time construction and periodization; (2) multiple temporal relations within one account in Chronicles and their significance for understanding both reading strategies of the intended and primary readerships and the organization of their memories of the past; (3) chaotic tendencies and their non-random distribution in the past that the readers are asked to remember and vicariously partake through reading and studying; (4) the significance of a memory of the past in which the size of armies diminishes through time; (5) concepts of “otherness” and the remembrance of some concrete constructions of “otherness” through the reading and rereading of the book; (6) otherness and the question of northern Israel; (7) attributes associated (or not) with being a Jerusalemite; and (8) on deontological vs. consequentionalist approaches to evaluate whether actions are to be judged right or wrong and the influence of a continuous remembrance of related events narrated in 2 Chronicles 25.  相似文献
