Inelastic spectra to predict period elongation of structures under earthquake loading

Period lengthening, exhibited by structures when subjected to strong ground motions, constitutes an implicit proxy of structural inelasticity and associated damage. However, the reliable prediction of the inelastic period is tedious and a multi‐parametric task, which is related to both epistemic and aleatory uncertainty. Along these lines, the objective of this paper is to investigate and quantify the elongated fundamental period of reinforced concrete structures using inelastic response spectra defined on the basis of the period shift ratio (T_in/T_el). Nonlinear oscillators of varying yield strength (expressed by the force reduction factor, R_y), post‐yield stiffness (a_y) and hysteretic laws are examined for a large number of strong motions. Constant‐strength, inelastic spectra in terms of T_in/T_el are calculated to assess the extent of period elongation for various levels of structural inelasticity. Moreover, the influence that structural characteristics (R_y, a_y and degrading level) and strong‐motion parameters (epicentral distance, frequency content and duration) exert on period lengthening are studied. Determined by regression analyses of the data obtained, simplified equations are proposed for period lengthening as a function of R_y and T_el. These equations may be used in the framework of the earthquake record selection and scaling. Copyright © 2015 John Wiley & Sons, Ltd.

碳酸盐团簇同位素约束下塔中隆起奥陶系热历史

碳酸盐团簇同位素是近年来兴起的一种新型古温标, 其有效地解决了碳酸盐岩沉积盆地缺乏常用古温标的现状, 对于沉积盆地热史恢复具有重要意义.本文采集了塔中地区奥陶系碳酸盐岩钻井取芯样品, 利用一阶近似模型模拟了塔中隆起碳酸盐团簇同位素温度(T_Δ47)热演化路径, 并结合等效镜质体反射率约束了塔中隆起的热历史.塔中隆起大地热流自奥陶纪到现今总体呈降低趋势, 自60~70 mW·m^-2降低至40~50 mW·m^-2, 二叠纪由于火成岩入侵造成热流短暂升高至60~70 mW·m^-2.模拟结果认为, 北部斜坡带及潜山构造带受火成岩影响显著, 北部斜坡带及潜山构造带在二叠纪最高温度分别达到160~170 ℃及180~190 ℃; 而塔中南缘未受影响, 中生代或者现今为最高温度130~140 ℃.总的来说, 碳酸盐团簇同位素在热史领域的研究目前还处于探索阶段, 未来有望在重排规律、T_Δ47影响因素以及模型理论方面有待进一步完善, 团簇同位素也将在热史领域的研究中产生愈加重大的影响力.

     

克拉通地幔形成与演化及对大陆命运制约因素的思考

岩石圈地幔属性主要由熔体抽取和交代作用程度共同决定,与岩石圈起源、大陆稳定性、宜居环境演变等密切相关。全球古老大陆的命运差别很大,有的长期稳定、有的遭受破坏,其控制因素可能包括大陆根地幔形成时熔融条件和后续交代改造过程等。本文总结前人研究资料发现,南非克拉通长期处于板块离散背景下,并经历了多期地幔柱活动,岩石圈地幔主体保持难熔属性、局部发生富集;华北克拉通长期处于板块汇聚背景下,并在显生宙发生强烈岩石圈减薄、改造和地幔置换作用,仅局部有难熔地幔残留。我们认为,亟需对不同命运克拉通之下的岩石圈地幔开展早期熔融条件和交代演化历史对比研究,寻找控制大陆命运的先天条件和后天因素。研究结果可以为大陆起源、宜居星球演化等关键科学问题提供制约。

     

Oscillations of levels and cool phases of the Laurentian Great Lakes caused by inflows from glacial Lakes Agassiz and Barlow-Ojibway

Two distinct episodes of increased water flux imposed on the Great Lakes system by discharge from upstream proglacial lakes during the period from about 11.5 to 8 ka resulted in expanded outflows, raised lake levels and associated climate changes. The interpretation of these major hydrological and climatic effects, previously unrecognized, is mainly based on the evidence of former shorelines, radiocarbon-dated shallow-water sediment sequences, paleohydraulic estimates of discharge, and pollen diagrams of vegetation change within the basins of the present Lakes Superior, Michigan, Huron, Erie and Nipissing. The concept of inflow from glacial Lake Agassiz adjacent to the retreating Laurentide Ice Sheet about 11–10 and 9.5–8.5 ka is generally supported, with inflow possibly augmented during the second period by backflooding of discharge from glacial Lake Barlow-Ojibway.Although greater dating control is needed, six distinct phases can be recognized which characterize the hydrological history of the Upper Great Lakes from about 12 to 5 ka; 1) an early ice-dammed Kirkfield phase until 11.0 ka which drained directly to Ontario basin; 2) an ice-dammed Main Algonquin phase (11.0–10.5 ka) of relatively colder surface temperature with an associated climate reversal caused by greater water flux from glacial Lake Agassiz; 3) a short Post Algonquin phase (about 10.5–10.1 ka) encompassing ice retreat and drawdown of Lake Algonquin; 4) an Ottawa-Marquette low phase (about 10.1–9.6 ka) characterized by drainage via the then isostatically depressed Mattawa-Ottawa Valley and by reduction in Agassiz inflow by the Marquette glacial advance in Superior basin; 5) a Mattawa phase of high and variable levels (about 9.6–8.3 ka) which induced a second climatic cooling in the Upper Great Lakes area. Lakes of the Mattawa phase were supported by large inflows from both Lakes Agassiz and Barlow-Ojibway and were controlled by hydraulic resistance at a common outlet — the Rankin Constriction in Ottawa Valley — with an estimated base-flow discharge in the order of 200000 m³s^–1. 6) Lakes of the Nipissing phase (about 8.3–4.7 ka) existed below the base elevation of the previous Lake Mattawa, were nourished by local precipitation and runoff only, and drained by the classic North Bay outlet to Ottawa Valley.Geological Survey of Canada Contribution 42488.This is the twelfth of a series of papers to be published by this journal that was presented in the paleolimnology sessions organized by R. B. Davis and H. Löffler for the XIIth Congress of the International Union for Quaternary Research (INQUA), which took place in Ottawa, Canada in August 1987.

Fresh thing for freshman: Exploring a blended method on teaching the history of geographic thought

It is necessary for undergraduates majoring in geography to learn the history of geographic thought. Although there are different cultural and educational backgrounds between China and the West, teaching methods such as text teaching, students’ presentations and group learning are suitable for most of teachers and students even from different countries and regions. The blended method is helpful to popularize history of geographic thought and improve the level of teaching and learning. Owing to lack of the class on the history of geographic thought in countries like China, the authors try to explore a blended method for the first-year geography undergraduates and to assess the effects of this teaching based on some questionnaires. The students have different benefits and responses to this class. A special group consisting of one teacher and several undergraduates does the research and coauthors the paper through making questionnaire, interviewing and analyzing materials from 67 freshmen majoring in human geography and geography science (teacher-training) in China. For the undergraduates especially from the countries like China, it is well worth making the history of geographic thought become a necessary and interesting class.     

Volcanic and Tectonic Framework of the Hydrothermal Activity of the Izu–Bonin Arc

In the Izu–Bonin Arc, hydrothermal activities have been reported from volcanoes along present‐day volcanic front, a rear arc volcano and a back‐arc rift basin as well as a remnant arc structure now isolated from the Quaternary arc. It is widely known that characteristics of hydrothermal activity (mineralogy, chemistry of fluid etc.) vary depending upon its tectonic setting. The Izu–Bonin Arc has experienced repeated back‐arc or intra‐arc rifting and spreading and resumption of arc volcanism. These characteristics make this arc system a suitable place to study the tectonic control on hydrothermal activity. The purpose of the present paper is, therefore, to summarize volcanotectonic setting and history of the Izu–Bonin Arc in relation to the hydrothermal activity. The volcanotectonic history of the Izu–Bonin Arc can be divided into five stages: (i) first arc volcanism (boninite, high‐Mg andesite), 48–46 Ma; (ii) second arc volcanism (tholeiitic, calc‐alkaline), 44–29 Ma; (iii) first spreading of back‐arc basin (Shikoku Basin), 25–15 Ma; (iv) third arc volcanism (tholeiitic, calc‐alkaline), 13–3 Ma; and (v) rifting in the back‐arc and tholeiitic volcanism along the volcanic front, 3–0 Ma. Magmas erupted in each stage of arc evolution show different chemical characteristics from each other, mainly due to the change in composition of slab‐derived component and possibly mantle depletion caused by melt extraction during back‐arc spreading and prolonged arc volcanism. In the volcanotectonic context summarized here, hydrothermal activity recognized in the Izu–Bonin Arc can be classified into four groups: (i) present‐day hydrothermal activity at the volcanic front; (ii) active hydrothermal activity in the back arc; (iii) fossil hydrothermal activity in the back‐arc volcanoes; and (iv) fossil hydrothermal activity in the remnant arc. Currently hydrothermal activities occur in three different settings: submarine caldera and stratocones along the volcanic front; a back‐arc rift basin; and a rear arc caldera. In contrast, hydrothermal activities found in the back‐arc seamount chains were associated with rear arc volcanism in Neogene after cessation of back‐arc spreading of the Shikoku Basin. Finally, sulfide mineralization associated with boninitic volcanism in the Eocene presumably took place during forearc spreading in the initial stage of the arc. This type of activity appears to be limited during this stage of arc evolution.
