摘 要

本工程为南京市六合区职校1#宿舍楼, 位于南京市六合区。

该公寓楼楼主体结构采用钢筋混凝土现浇框架结构，横向3跨，中间跨跨度3m。房屋总高约22.8m，共6层，各层层高均为3.3米，建筑场地约45m *18m，抗震设防烈度为7度，设计基本地震加速度值为0.10g。建筑立面规整，采用白色瓷砖装饰外墙，女儿墙实心砖砌筑，除正门为玻璃门外，其余均采用实木门，窗为塑钢窗。

本设计主要包括建筑设计和结构设计两部分。建筑设计，包括平面定位图设计、平面设计、立面设计、剖面设计。结构设计，框架结构设计主要包括：结构选型，梁、柱、墙等构件尺寸的确定，重力荷载计算、横向水平作用下框架结构的内力和侧移计算、纵向地震作用计算、水平地震作用下横向框架内力分析、竖向荷载作用下横向框架的内力分析、内力组合、截面设计、基础设计。其中,基础设计又包括基础选型、基础平面布置、地基计算等。

在设计中,认真贯彻了“适用、安全、经济、美观”的设计原则，进一步掌握了建筑与结构设计全过程、基本方法和步骤。

第一章

1.1结构平面简图

本工程横向框架计算单元取图虚线斜线部分所示范围，框架的计算简图假定底层柱下端固定于基础。根据任务书给出该工程场地类型为Ⅱ类，地质条件较好，初步确定本工程采用柱下独立基础，挖去所有杂填土，基础置于第二层粉质粘土层上，基底标高为设计相对标高-3m。柱子高度为h₁=3.3 1.8-0.6=4.5m（初步假设基础高度为0.6m），二~六层柱高为：h₂~h₆=3.3m。柱节点刚接，横梁的计算跨度取柱中心至中心间距离，三跨分别为：l=7500mm、3000mm、7500mm，计算简图如图2.3。
