14、度18.90m，室内外高差0.450m，基础顶面距离室外地面1.1m，基础采用柱下独立基础。 该教学楼楼拥有教室、教学办公室，行政办公室、实验室、音乐教室、计算机房，合班教室等。楼内设有两个楼梯，楼梯开间均为3.6m，进深均为7.2m，楼梯的布置均符合消防、抗震的要求。框架梁、柱、楼面、屋面板板均为现浇。1.2设计资料场地面积：长宽= 6020m；最高气温：35 ；最低气温：-10；主导风向：冬季为西北风，夏季为东南风；基本风压：0.4kN/m2基本雪压：0.5kN/m2年降雨量：1450mm暴雨强度： 119mm/h场地地震效应：建筑物所在地区地震设防烈度为7度，设计基本地震加速度值为0.1
15、5g。拟建场地土类型为中软场地土，类建筑场地，设计地震分组为第一组。建筑结构的安全等级：二级设计使用年限：50年环境类别：上部结构为I类，基础为a类 建筑抗震设防类别：丙类 1.3 工程特点 本工程为七层，主体高度为18.90米，属多层建筑。多层建筑采用的结构可分为钢筋混凝土结构、钢结构、钢-钢筋混凝土组合结构等类型。根据不同结构类型的特点，正确选用材料，就成为经济合理地建造多层建筑的一个重要方面。经过结构论证以及设计任务书等实际情况，以及本建筑自身的特点，决定采用钢筋混凝土结构。框架结构体系是由梁、柱构件通过节点连接构成，既承受竖向荷载，也承受水平荷载的结构体系。这种体系适用于多层建筑及高度不大的高层建筑。本建筑采用的是框架机构体系，框架结构的优点是建筑平面布置灵活，框架结构可通过合理的设计，使之具有良好的抗震性能；框架结构构件类型少，易于标准化、定型化；可以采用预制构件，也易于采用定型模板而做成现浇结构，本建筑采用的现浇结构。 由于本次设计是教学楼设计，要求有灵活的空间布
