Design calculations first select 8 shaft framework are hand count. In determining the structure after decorating, load statistics, calculation of constant load and the vertical load (live load) under the action of structural internal force (moment of flexure, shear force and axial force) and in the wind load structural internal force; Then force combination, find out the most unfavorable one group or several groups of internal force calculation combination, and reinforcement. Then use to structure software PKPM the spatial calculation analysis, get board, beams and columns of internal force envelope and reinforcement, including envelope to board the elastic theory according to the internal force calculation. Also conducted indoor stair design, completed the rest flat bedplate, ladder section board, ladder mouth beam of internal force and the component such as reinforcement, finally calculated according to the calculation result mapped the board, beams and columns and the structure of the stairs construction drawings. Keywords： frame；internal force calculation； PKPM reinforcement 目 录 摘要 I Abstract II 1.工程概况 1 2. 框架结构布置及计算简图 2 2.1 梁柱尺寸 2 2.1.1 梁截面尺寸 2 2.1.2 柱截面尺寸 2 2.2 8轴框架计算简图 3 2.3 梁柱线刚度 4 3. 荷载计算 5 3.1 竖向恒荷载标准值计算 5 3.2 竖向活荷载标准值计算 10 3.3竖向荷载下框架受荷总图 10 3.3.1 梁上线荷载计算 10 3.4 恒活荷载作用下框架荷载简图 15 3.4.1恒载作用下框架荷载简图 15 3.4.2活载作用下框架荷载简图 16 3.5 风荷载标准值计算 16 4. 荷载内力分析与计算 19 4.1 恒、活荷载作用下框架内力计算 19 4.1.1 恒载、活载作用下梁的固端弯矩计算 19 4.1.2 竖向荷载弯矩计算 19 4.2恒载、活载作用下剪力计算 19 4.3恒载、活载作用下轴力计算 19 4.4风荷载作用下框架内力计算 27 4.4.1反弯点高度确定 27 4.4.2风荷载作用下产生的弯矩 28 4.4.3 风荷载作用下梁、柱剪力 29 5. 内力组合 31 5.1 梁的内力组合 34 5.2 柱的内力组合 40 6. 框
