1、框架结构体系毕业设计论文摘要框架建筑结构是多高层建筑结构的主要类型，具有承载力和刚度大，耐久性和耐火性好可模性好等优点。本工程为框架结构体系，柱距为7.2m，跨度为6.0m，采用横向承重方案，框架中柱偏向走廊一侧。地震作用下内力和侧移的计算分析用底部剪力法和D值法，计算结果变截面处上下层柱刚度比为0.7，层间相对弹性转角均小于0.18%。横向荷载作用下内力分析用反弯点法。竖向荷载作用下内力分析用弯矩二次分配法，梁柱内力组合时需考虑地震作用效应组合。梁柱箍筋均采用HPB300热轧钢，受力钢筋根据计算需要选择HRB335以上热轧钢。地基处理用灰土挤密桩法，桩
2、径400mm，桩间距为935mm，处理范围每边超出基础地面外边缘2m，灰土桩用振冲法施工。基础梁纵向等截面每边宽出框架柱边缘50m。条形基础内力计算用倒梁法，分布筋按构造配筋。边坡采用抗滑桩支护，抗滑桩间距6m，桩长14.5m，计算结果用理正岩土软件验算。地基强度经验算满足要求。关键词：框架结构体系；内力组合；地震作用；地基强度。第58页AbstractFramestructureisthemaintypesofhigh-risebuildings,havebearingcapacityandrigidity,durabilityandgoodcarvi
