Inelastic Displacement Ratios for Nonstructural Components Subjected to Floor Accelerations

This paper describes a study on the characterization of the Inelastic Displacement Ratios (IDRs) of inelastic acceleration-sensitive nonstructural components subjected to floor accelerations obtained from the linear analysis of multistory building structures under far-field ground accelerations. Several building models having different structural systems and a number of stories were considered. IDRs were obtained from the displacement response of elastic and inelastic single-degree-of-freedom systems subjected to floor accelerations. Similarities and differences between floor acceleration IDRs and ground acceleration IDRs were identified, and efforts were made to explain the differences. Finally, a predicting equation for floor acceleration IDRs is proposed and validated.     

宋代官员墓葬相关问题刍议

从现有考古材料来看,与前代相比,宋代墓葬体现的等级制度并不明显,而官员墓葬似恰是造成这一状况的原因.原本应当尊奉制度、为民表率的官员群体中,有很大一部分官员并未向下传递上层的丧葬文化,反而被出身之地或归葬之所的富裕平民阶层同化.由此使其地下墓葬部分呈现出“地方化”的特征.而这一情形,所反映的可能是两宋时期,民间经济力量...     

《后山逸诗笺》禅源举隅

《后山逸诗》几乎占后山诗的三分之一,由于历史原因．很少有人为其作注。而且宋人,特别足江西诗派作诗,喜欢“以学问为诗”,涉及面很广。全面注释其作品,目前以个人之力难以达其的旨。笔者选其巾与禅理密切者．将禅门故实检出,并稍加训释。     

猗傩、■蛮的词义辨析──先秦审美风尚琐议

［摘要]本文对猗傩、 蛮两个词语进行辨析,用以澄清对《诗经》某些篇章的误解,揭示先秦审美风尚的基本走势。猗傩,指的不是轻盈柔美,而是指盛大繁多。 蛮,指的不是小鸟,而是指比翼鸟。这是以上两个词语在《诗经》中的基本含义,从中可以看出那个时代以盛大繁多为美,以和谐为美的风尚。     

近代日本的国际秩序观与外交取向

明治初期,维新政府中枢就已深刻地了解到日本所置身的国际社会和国际形势,确立起包括对自己和世界进行重新定位以及日本未来发展方向在内的国际秩序观。近代日本国际秩序思想中的上下秩序认识与欧洲近代国际秩序思想的二重原理体系如出一辙,并在明治维新后迅速与国家政权结合起来,最终确立起对欧美屈从,对东亚邻国强硬的双重外交路线。     

Study on Low-Frequency Characterizations of Pulse-Type Ground Motions through Multi-Resolution Analysis

This article makes an attempt to investigate the low-frequency characterizations of pulse-type ground motions through ground motion components instead of original records. A decomposed method based on multi-resolution analysis is introduced in this article. The accuracy and validity of the method is tested in frequency domain, time domain and dynamic response. A dataset of 398 low-frequency components is obtained after the decomposition of 91 typical pulse-type records. A probabilistic model to describe the proportion of low-frequency components in corresponding original ground motions is established. At last, the decomposed method is used to investigate the impulsive characterizations of pulse-type ground motions.     

海外华人跨国主义实践的模式及其差异——基于美国与新加坡的比较分析

论文参考有关跨国主义的理论文献和实证研究,分析了移民个人、移民社会以及民族国家在国际移民进程和跨国活动中所扮演的不同角色,考察了在美国和新加坡的华人新移民及其社团组织与祖籍国之间互动模式的变化。结果显示,由于国际移民的迁移历史以及移居国(地)结构的多重差异,导致了海外华人社会在人口构成和族裔社区建设等方面存在显著差异。个人、社团、祖籍国和移居国实际上并不是单方面地影响着海外华人的跨国活动及其与祖籍国的互动关系,他们的互动关系还受到国家关系和地缘政治等宏观因素的制约。因此,国际移民参与跨国活动的主要目的是为了寻求更好的、更广阔的创业和就业机会,以便提高个人和族群在移居国的社会地位,但其结果因移居国社会的结构因素影响而产生差异。     

A Multi-Mode Method for Estimation of Floor Response Spectra

A new simplified procedure for estimation of floor response spectra (FRS) is proposed. This methodology enriches the most common procedures using nonlinear response-history analysis to predict FRS by including a direct multi-mode technique to estimate FRS. A novel feature of the procedure is that the coupling effect is considered to establish equivalent modal systems and the FRS are developed by incorporating capacity spectrum method in conjunction with ductility-based FRS for each modal system. Both the proposed method and the traditional method are applied to three steel moment frame structures, and a reasonable accuracy is demonstrated.

《论语·八佾》“文献”

《论语》孔子所云“献”是具有证据功能的字资料。历代学训“献”为“贤”一误再误,各种诠释皆不圆孔子之说。据“献”字本义和古代注重收集民情传统考查,“献”是下情上达的字资料,与“”的区别仅在于强调其最初来自庙堂之下进献。当下情上达的字资料,“藏于秘室’’而与庙堂原有之“”久居共处,或两糅合一起时,“”与“献”的区别也就日益消失而没有意义,故笼而统之称为“献”。
