Modelling and Seismic Response Analysis of Italian Code-Conforming Base-Isolated Buildings

ABSTRACT

This paper reports on results of nonlinear analyses performed within the RINTC project on an RC building isolated with different systems (High Damping Rubber Bearings, High Damping Rubber Bearings and Flat Sliding Bearings, Friction Pendulum System) and designed according to the Italian design code. The seismic response has been evaluated under different seismic input levels of two sites with different hazard and by considering two Limit States: Global Collapse and Usability-Preventing Damage. The influence of seismic stoppers and modelling uncertainties is also evaluated. Results permit to compute the implicit collapse risk and to identify critical aspects of current design procedures.     

Seductive Alienation: The American Way of Life Rearticulated in Occupied Japan

This article explores how the notion of American domesticity promoted by US occupation forces in postwar Japan was decoded and rearticulated by non-elite Japanese women, a social group that has been largely overlooked in studies of the global promotion of the American way of life during the early Cold War years. Specifically examined here is the case of Takehisa Chieko, an actress and the wife of an American officer, who enjoyed high visibility in popular women’s magazines as the embodiment of the idealised postwar American lifestyle. A reading of Takehisa’s magazine writings, interviews, and photographs suggests, however, that she was far from a passive recipient and transmitter of this cultural message. As such, a close unpacking of her rearticulation of the idea of American domesticity toward the particular socio-cultural fabric of postwar Japan reveals the particular nature of this supposedly universal American model. In demonstrating the various dilemmas that stemmed from confronting both the seductive and alienating features of the American way as promoted in occupied Japan, this study illuminates a point of rupture in the larger US global promotion of American domesticity as a means toward cultural hegemony and political containment in the early Cold War period.     

Hydraulic and hydrochemical properties of deep sedimentary reservoirs of the Upper Rhine Graben,Europe

Hydraulic and hydrochemical data from several hundred wells mostly drilled by the oil and gas industry within the four deep carbonate and siliciclastic reservoirs of the Upper Rhine Graben area in France and Germany have been compiled, examined, validated and analysed with the aim to characterize fluids and reservoir properties. Due to enhanced temperatures in the subsurface of the Upper Rhine Graben, this study on hydraulic and hydrochemical properties has been motivated by an increasing interest in deep hydrogeothermal energy projects in the Rhine rift valley. The four examined geothermal reservoir formations are characterized by high hydraulic conductivity reflecting the active tectonic setting of the rift valley and its fractured and karstified reservoirs. The hydraulic conductivity decreases only marginally with depth in each of the reservoirs, because the Upper Rhine Graben is a young tectonically active structure. The generally high hydraulic conductivity of the reservoir rocks permits cross‐formation advective flow of thermal water. Water composition data reflect the origin and hydrochemical evolution of deep water. Shallow water to 500 m depth is, in general, weakly mineralized. The chemical signature of the water is controlled by fluid–rock geochemical interactions. With increasing depth, the total of dissolved solids (TDS) increases. In all reservoirs, the fluids evolve to a NaCl‐dominated brine. The high salinity of the reservoirs is partly derived from dissolution of halite in evaporitic Triassic and Cenozoic formations, and partly from the fluids residing in the crystalline basement. Water of all four reservoirs is saturated with respect to calcite and other minerals including quartz and barite.     

圆明园新证——万方安和考

万方安和是清代皇家离宫圆明园中独具特色的园林景建筑之一,其主题以万字房为重心,十字亭为结点,一字长楼山高水长为回应,形成山环水聚、万年如意的园林宫殿形局。其经营意象援引佛教宇宙图式、兼及禅宗沩仰宗风"圆相"奥旨,同时溯源汉地明堂,既是对"圆明主题"的进一步深化,又是雍正皇权极度膨胀在造园理念方面的突出表现。     

明清科举的正途与异途——关于福建、江西、安徽族谱资料的分析

明清时期,科举制度的推行与家族制度的发展呈现相辅相成的关系,获得功名是许多家族之凝成与延续的重要前提。获得功名的途径大体上分正途与异途两种。从族谱资料的分析可知:家族中的正途出身与异途出身往往相互支撑,共同为家族的延续和发展作出贡献。有的是前期多正途出身,后期多异途出身。有的则先由异途出身,后代逐渐走上正途。从各自的水平和行迹看,异途或许也能在一定程度上起到搜罗遗才的作用。     

论荀悦的历史认识论

荀悦在前人的基础上 ,对历史认识的目的、方法、思维方式、检验标准等提出了许多有价值的见解。他阐明以史为鉴的必要性 ,将历史认识与取鉴资治有机结合起来 ;强调认识历史要透过现象看本质 ,通过区分类例 ,由此及彼 ,知微察著 ,去伪存真 ,获得对历史的理性认识 ;指出应以发展变易的观点审视历史 ,不能墨守成规 ,应当因时立制 ,分析事物时应看到其内部相互对立而又相互联系的不同方面 ;要求以儒家思想作为考察历史的理论原则 ,将主观认识与客观事实相参验 ,以真实作为检验历史认识的标准。荀悦的历史认识论值得认真加以总结     

论唐代的封驳制度

唐代以封还皇帝诏命为对象的封驳制度渊源于两汉,酝酿于初唐,形成于唐代中后期,主要由门下省官员给事中职掌。封驳的目的在于追救缺失,防患于未然,而封还诏敕并加以驳正则是其最主要的方式。在权力高度集中的封建皇权社会,封驳制度在加强权力监督、抑制皇权膨胀等方面无疑有着积极的意义,然而这种作用也不宜高估,唐代中后期三省制的破坏在很大程度上妨碍了封驳作用的发挥,而当政者能否接受逆耳之言、给事中能否履行职责也同样决定着封驳作用的发挥。     

晋“假虞伐虢”的道路和战场问题的再探讨——兼与靳生禾、谢鸿喜二先生商榷

公元前658年与655年晋两次"假道于虞以伐虢"道路和战场,与"鄍邑"、与"茅津"均无涉。晋第一次"假虞伐虢",其战场在虢之下阳,所假"虞道"与虢之下阳均在黄河以北。第二次晋"假虞伐虢"灭虢都上阳,师还灭虞,其战场分置于黄河南、北。其行军路线:第一次伐虢邑克下阳,是从晋都绛发兵,经虞坂——虞城——颠軨——傅岩——盘南——下阳;第二次伐虢灭上阳,重走第一次"虞道"经傅岩、盘南至下阳,再从"太阳渡"过河取虢都上阳。原路师还,顺道灭虞,返晋都绛。晋"假虞伐虢"所假"虞道",主指"虞坂——虞城——颠軨"路段。虞坂即盐坂、即青石槽。颠軨即軨桥。宋代以前平陆所设县治均在"大阳故城",即今茅津渡以东约两公里"下滩"一带。春秋时期,傅岩、茅津既不属虞,也不归虢,而是"戎人"与"夷人"的杂居区。古代"鄍"通"冥",所谓"虞邑",此乃暗城也。
