摘要 本项目为B大学教学办公楼，建筑高度为17米，共五层，总建筑面3500㎡，设计年限为50年，抗震设防烈度为6度，结构类型为多层钢筋混凝土框架结构，楼板为双向板，楼梯采纳板式楼梯，基础采纳柱下独立基础。框架结构内力计算时，在竖向荷载作用下框架内力近似计算时采纳分层法，在水平荷载作用下框架内力近似计算时采纳改进反弯点法（D值法）。在计算过程中对梁的弯矩进行了调幅，板内力计算采纳弹性理论计算方法。对建筑中出现的墙体均直接放在梁上墙、板的重量传给梁，梁再传给柱，传力路线明确。关键词 框架结构 独立基础 板式楼梯 分层法 D 值法目录第 一 章 建筑设计资料及做法说明1.1 建筑设计资料 ······································································································11.2 建筑做法说明······································································································1第 二 章 结构布置及选型2.1 结构布置··············································································································42.3 梁柱截面、梁跨度及柱子高度的确定······························································42.3框架计算简图······································································································52.4 梁、柱惯性矩、线刚度、相对线刚度计算······················································5第 三 章 菏载计算3.1 竖向荷载统计 ················································································...
