摘要
文中以混凝土框架结构为研究对象,结合抗震设防烈度和分项系数组合的9 种工况,简要分析了荷载分项系数、水平地震作用分项系数调整对框架结构设计的影响.结果表明,随着抗震等级的提高,荷载分项系数的调整对框架梁影响逐渐减小;水平地震作用系数的提高对框架梁的配筋增量几乎不受抗震设防烈度的影响.
Abstract
Taking the RC frame structure as the topic,through 9 different seismic fortification intensities and partial coefficients combination,this paper briefly analyzes the influence of the adjustment of load partial coefficients and horizontal seismic action coefficient on the design of frame structure.The results show that:With the improvement of seismic grade,the influence of the adjustment of load component coefficient on the frame beams gradually decreases.Under the 3 intensities of earthquake fortification,the reinforcement increment of frame beams is practi-cal unanimity due to the increase of horizontal seismic action coefficient.
