【摘要】：將K型偏心支撐鋼框架的耗能梁換成形狀記憶金屬(Shape Memory Alloy,簡稱SMA)材料,通過SMA材料的超彈性為結(jié)構(gòu)提供復(fù)位力,實(shí)現(xiàn)自復(fù)位K型偏心支撐鋼框架的構(gòu)想。為考察該新型自復(fù)位K型偏心支撐鋼框架的抗震性能,應(yīng)用ANSYS有限元軟件建立K型偏心支撐鋼框架多尺度有限元模型,在驗(yàn)證有限元模型合理的基礎(chǔ)上,設(shè)計(jì)傳統(tǒng)K型偏心支撐鋼框架和自復(fù)位K型偏心支撐鋼框架,采用10條強(qiáng)震記錄分別進(jìn)行罕遇地震作用下的彈塑性動力時(shí)程分析。研究表明:新型自復(fù)位K型偏心支撐鋼框架震后殘余變形較小,能較好地實(shí)現(xiàn)結(jié)構(gòu)的自復(fù)位,耗能梁腹板處應(yīng)力分布與傳統(tǒng)結(jié)構(gòu)較為相似,但耗能能力及側(cè)向變形能力較傳統(tǒng)結(jié)構(gòu)有所弱化。
[Abstract]:The energy dissipation beam of K type eccentrically braced steel frame is replaced by shape Memory alloy material of shape memory metal. The supra-elasticity of SMA material provides the reset force for the structure and realizes the conception of self-reposition K type eccentrically braced steel frame.In order to investigate the seismic behavior of the new steel frame with self-reset K eccentrically braced steel frame, the multi-scale finite element model of K eccentrically braced steel frame is established by using ANSYS finite element software, and the finite element model is verified to be reasonable.The traditional K type eccentrically braced steel frame and the self reduction K type eccentric braced steel frame were designed. The elastoplastic dynamic time history analysis was carried out under rare earthquake using 10 strong earthquake records.The results show that the residual deformation of the new type K eccentrically braced steel frame is small after the earthquake, and the stress distribution at the web of the energy dissipation beam is similar to that of the traditional structure.However, the energy dissipation capacity and lateral deformation capacity are weaker than those of traditional structures.
