高层框架-防屈曲钢板墙体系方案布置研究

Jianzhu Gangjiegou Jinzhan, 2015
防屈曲钢板墙(简称BRSPSW)是一种适用于高层钢结构的新型抗侧力构件,具有塑性性能好、滞回特性稳定、可独立变化墙板承载力和刚度以及布置灵活等优点,可克服支撑框架易受建筑功能限制的缺点。以某34层钢结构住宅为背景,首先提出BRSPSW适用性布置方式,并对其进行比选分析。然后基于结构弹性层间位移角要求,通过6组算例对D形布置BRSPSW跨越门洞传力转换进行了分析,提出了有效高宽比概念与BRSPSW体系方案设计阶段参考建议。

Elastoplastic Model for Buckling-restrained Braces:Response and Response Sensitivity Analysis

, 2013
在OPEnSEES中实现了一种最近研究的新型防屈曲支撑结构(brbS)的弹塑性本构模型的隐式算法,并基于直接微分法(dIrECT dIffErEnTIATIOn METHOd,简称ddM),推导实现其响应的参数敏感性分析算法。此模型能够很好地预测brbS的实验结果。同时,根据敏感性计算结果能够分析brb本构参数对结构响应的影响和相对重要性,分析结果可用于基于梯度计算的结构优化、结构可靠性和模型修正中。选取一个配置brbS的4层钢框架进行实例研究,用ddM计算结果与有限差分法(fInITE ...

无粘结内藏钢板支撑剪力墙的墙板约束宽度分析

Jianzhu Gangjiegou Jinzhan, 2011
为了研究单斜无粘结内藏钢板支撑剪力墙中,墙板为限制支撑整体失稳所需的约束宽度,通过有限元分析,考察了构造参数的变化对墙板约束宽度的影响。这些参数包括混凝土墙板厚度,钢板支撑的长度、宽度、厚度及钢材屈服应力。结果表明,对于特定的支撑墙板,在墙板整体受弯开裂前,墙板约束宽度基本不变。同时,当其它构造参数相同时,仅变化支撑钢板的宽度、厚度及钢材屈服应力中的某一参数,墙板的约束宽度基本不变。约束宽度与支撑长度基本成正比,随墙板厚度的增大约束宽度逐渐减小;墙板整体受弯开裂后,随着支撑轴向压力的增加 ...
