【摘要】：K形高強(qiáng)鋼組合偏心支撐(K-HSS-EBF)是指耗能連梁和支撐采用Q345鋼,而框架梁、框架柱采用高強(qiáng)度鋼(如Q460)。為研究其在罕遇地震作用下的抗震性能,在試驗(yàn)研究的基礎(chǔ)上,采用直接基于位移的抗震設(shè)計(jì)方法設(shè)計(jì)了5層、8層和12層算例,分別進(jìn)行靜力推覆分析和動(dòng)力彈塑性分析,研究高強(qiáng)鋼組合偏心支撐鋼框架在罕遇地震作用下層間側(cè)移分布和破壞模式。研究結(jié)果表明:直接基于位移的抗震設(shè)計(jì)方法設(shè)計(jì)的算例在罕遇地震作用下,結(jié)構(gòu)的層間側(cè)移滿足我國(guó)現(xiàn)行抗震規(guī)范的要求,結(jié)構(gòu)呈理想的漸進(jìn)式梁鉸屈服機(jī)構(gòu),并證明該設(shè)計(jì)方法的合理性和可靠性。
[Abstract]:K-HSS-EBF (K-HSS-EBF) means that the energy dissipation beam and the bracing are Q345 steel, while the frame beam and frame column adopt high strength steel (such as Q460). In order to study its seismic performance under the action of rare earthquake, based on the experimental study, five stories 8 stories and 12 stories were designed by direct displacement-based seismic design method, and the static force nappe analysis and dynamic elastoplastic analysis were carried out, respectively. The lateral distribution and failure mode of eccentrically braced steel frame with high strength steel under rare earthquake are studied. The results show that the seismic design method based on displacement can meet the requirements of the current seismic code in our country, and the structure is an ideal progressive beam hinge yield mechanism. The rationality and reliability of the design method are proved.
