Jianzhu Gangjiegou Jinzhan, 2021 对7根设肋薄壁方钢管混凝土柱进行了拟静力试验,研究了加劲肋设置数量、轴压比和长细比对试件的承载能力、延性和耗能能力的影响。同时使用ABAQUS软件对带肋薄壁方钢管混凝土柱进行了受力全过程分析,模拟结果与试验结论基本一致。研究结果表明:在达到承载力前,无肋试件已经发生鼓曲,鼓曲在达到承载力后迅速增大从而导致焊缝开裂,钢管对混凝土的作用未充分发挥时试件就已破坏。带肋试件由于加劲肋对外部钢管的拉结作用,延缓了试件局部鼓曲的发生,试件材料性能得以充分利用,因此带肋试件的承载力、延性性能和耗能性能均优于无肋试件 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

Jianzhu Gangjiegou Jinzhan, 2005 韧性斜撑构材由主受力组件与侧撑组件组成,主受力组件承担轴力而侧撑组件则在防止主受力组件受压挫屈,由于主受力组件不挫屈,因此能充分发挥材料之强度与韧性,成为一高强度且具高消能容量之斜撑构材。以韧性斜撑构材作为同心斜撑构架中之斜撑构材,此同心斜撑构架即称之为韧性同心斜撑构架,此种构架具有稳定之迟滞行为与高韧性之特性,为一优良之耐震结构系统。本文叙述韧性斜撑构材与韧性同心斜撑构架之力学与耐震行为,并根据其力学与耐震行为提出建议之设计方法。本文为第二部分。

International Journal of Applied Linguistics, EarlyView.ABSTRACT This article examines the language life of young Malaysian Chinese immigrants in Australia and their construction of multi‐membership as reflected in their daily language behaviors. It develops the concept of everyday linguistic citizenship and uses this concept as a theoretical lens to understand how the young adults build, maintain, and ...

, 2023 利用有限元软件ABAQUS建立方形钢管混凝土叠合柱三面受火下的有限元模型，通过现有相关文献试验数据对有限元分析方法的有效性进行验证后，分析方形钢管混凝土叠合柱三面受火下的温度场分布、破坏形态、轴向位移-时间关系、内力重分布、应力、应变等力学性能，并对影响构件耐火性能的相关因素进行参数分析。结果表明，方形钢管混凝土叠合柱三面受火下的横截面温度场分布呈单轴对称形态，荷载比、长细比、柱截面尺寸、外部混凝土抗压强度、截面含钢率是影响构件耐火极限的主要影响因素。基于对各主要参数影响规律的系统分析 ...

Vocabulary Strategy Instruction in the Argentine EFL Context: Teachers’ Perspectives and Practices
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite extensive research on vocabulary strategy instruction (VSI), little has been known about teachers’ perspectives on how it is understood and implemented in practice. This study investigated Argentinian EFL teachers’ priorities in vocabulary instruction, their perceived knowledge of learner strategies for spoken vocabulary, and factors ...
