摘要

目前，为了增加高层结构的建设，选择具有巨大的抗风、抗震吸能能力的优化体系的重要性已被广泛考虑。自四十年前以来，钢剪力墙一直被用作刚性和高性能的横向体系。本文研究了钢管混凝土柱作为钢剪力墙竖向边界单元对钢结构抗震性能的影响。为此，通过SAP2000软件，采用非线性时程法对3个10层钢结构进行了分析，并对3个10层钢结构的顶板位移结果进行了比较。3个10层钢结构具有相似的平面和横向荷载职业体系:钢剪力墙、x型支撑、中等钢框架。在对钢剪力墙和CFT柱的两层单跨框架进行验证后，通过ABAQUS软件对3个单层结构进行了滞回和推覆分析。研究结果表明，与其他横向承载体系相比，剪力墙体系具有合适的刚度、阻力和延性。

Comparison between structural configurations designed by steel shear wall, moment resistant frame and X shape bracing systems

Nowadays, in order to increase construction of tall structures, the importance of choosing optimum systems, with a huge energy absorption capacity against wind and earthquake loads, has been widely considered. Since four decades ago, steel shear walls had been used as a stiff and high performance lateral system. This study is about the effect of concrete filled steel tubes (CFT) columns as vertical boundary elements of steel shear wall on seismic behavior of steel structures. Due to do this, three 10-storey steel structures, with similar plans and lateral load career systems of steel shear wall, coinciding X-bracing, and moderate steel frame were analyzed by means of non-linear, time-history method through SAP2000 software, and the results of roof displacement of them were compared with each other. Also after validating a two-storey, single-span frame sample with steel shear walls and CFT columns, 3 single-storey structures were analyzed by means of hysteresis and pushover, through ABAQUS software. The results of this study showed that a shear wall system presents suitable stiffness, resistance and ductility in comparison with other lateral bearing systems.

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
