Experimental Study of Steel-reinforced Concrete Columns under Sustained Axial Loads [PDF]

open access: yes, 2014
型钢混凝土柱是由混凝土、型钢和钢筋组合而成的结构构件,具有良好的承载性能。型钢混凝土柱结合了钢筋混凝凝土的刚度和型钢的强度,是一种非常经济适用的结构形式。作为混凝土包钢结构不仅增加了自身刚度,同时能够保护型钢免于遭受火灾和局部屈曲破坏。型钢混凝土结构具有抗震性能好、承载力高、耐火性和耐久性好等诸多优点,现广泛用于高层、超高层、大跨度结构等重要建筑中。随着型钢混凝土柱的广泛应用,国内外开展了大量的理论和试验研究。目前,国内外对于型钢混凝土柱的研究主要集中在极限承载能力、型钢与混凝土的共同工作性能 ...

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

Informal Digital Learning of English (IDLE) as Form‐Focused and Meaning‐Focused Activities: Refining its Measurement and Examining its Predictive Role in L2 Achievement and Confidence

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Acknowledging the limitations of existing measurement instruments in adequately capturing the distinct cognitive processes (e.g., form‐focused vs. meaning‐focused) involved in informal digital learning of English (IDLE), this paper asserts a pressing need to develop and validate robust instruments that measure form‐focused and meaning‐focused ...

Research on web stability and human-induced vibration of Concrete filled steel tubular with corrugated steel web composite structure [PDF]

open access: yes, 2014
波形钢腹板-钢管混凝土组合结构作为一种新型结构,可以发挥钢管混凝土抗压能力强和波形钢腹抗剪能力高的优点,其作为腹板的波形钢还具有自重轻、受力明确、施工方便、美观等优点,使得这种组合结构具有强大的竞争力和广泛的应用前景,作为一种新型结构,前人对其进行的理论与试验研究甚少。为此,本文在侨英人行天桥荷载试验的基础上,建立了该桥的有限元模型,对该桥的波形钢腹板稳定性和人致振动特性进行了有限元分析,并总结规律。本文的工作主要集中在以下几个方面: 通过对侨英人行天桥的荷载试验和有限元分析,结果表明 ...
