摘 要
本工程为某宿舍楼，楼层数为6层，建筑面积5098㎡，占地面积为850㎡，为了满足教学楼使用要求，将一层的层高定为3.9m，二层以上层高定为3.6m。本工程设计计算书计算内容全面，分别计算了楼板的配筋，框架的内力计算，内力组合，截面设计，然后计算了现浇板式楼梯，基础等等，任务书要求的设计计算。设计成果还包括了任务书要的全部建筑图和结构图。
Summary
Story high that this engineering is some to teaching building, transact the floor to count to 6 layers, construct the area 5098 ㎡, cover the area to 850 ㎡ for satisfying to transact the floor usage the request, will a the layer settle to 3.9 m, two above story high of layerses settle to 3.6 m.This engineering design calculation book calculation the contents is completely, and computed the floor knothole the inside dint, frame the calculation, inside dint the combination respectively, and cut a design calculation for design, then computing now sprinkling the plank type the stairs, foundation etc., mission book requesting.The design result still included the mission book the diagram of all buildings that wanted with the construction diagram.
