1工程概况1.1.工程名称：某学院学生宿舍楼设计（5-6层）。1.2.工程概况：建筑面积约为5000m2，是一幢6层的现浇钢筋混凝土框架结构体系的建筑物，层高均为3.0m，室内外高差为0.9m。1.3.设计条件：主导风向:冬季为北偏东风，夏季为东南风；C类粗糙程度，基本风压w0=0.35kN/m2，；雨雪条件：基本雪压为0.45kN/m2其它条件：抗震设防烈度7度。1.4材料使用：（1）.钢筋：多数纵向受力钢筋采用热轧钢筋HRB335,其余采用热轧钢筋HPB235。（2）.混凝土：梁柱板均使用C30类型的混凝土。1.5其它结构选型屋面：使用现浇钢筋混凝土板作为承重结构，屋面板按不上人屋面的使用荷载选用。楼面：使用现浇钢筋混凝土板，板厚为120mm。基础：使用柱下独立基础。2.1确定计算简图假定框架柱与基础顶面接触，框架梁与柱刚接，设计时为了计算的方便，使每个柱子的尺寸不变，于是梁的跨度和柱截面形心线之间的距离相等。底层的柱子高度为3.9m图2.22.2梁、柱截面尺寸的估算：梁截面BD跨：主梁：取h=600mmb=300mm故该框架的横梁与纵梁的初步设计截面尺寸为b×h=300mm×600mm次梁：h=400mm取b=200mm故框架的次梁初步设计截面尺寸为b×h=400mm×200mmDE跨：主梁：取与BD同样截面 柱截面柱截面取400mm×400mm2.2.1屋面与楼面的恒荷载标准值计算屋面120mm厚的现浇混凝土板0.12m×25＝3顶层抹灰10mm厚混凝土砂浆0.01×17＝0.017附加层3.50合计4.48标准层楼面：地面装饰0.65找平层20mm厚水泥砂浆0.02m×17＝0.34120mm厚现浇钢筋混凝土板0.12m×25＝3抹灰：10厚混合砂浆0.01m×17＝0.17合计：4.332.2.2屋面与楼面活荷载计算一.根据《荷载规范》与计算书查得：楼面：2.0走廊:2.5二.雪荷载Sk=1.0×0.45=0.452.2.3梁、柱、板的重力荷载计算梁自重：主梁：b×h=300mm×600mm主梁自重：0.3×25×（0.6-0.12）=2.85抹灰：0.01×[(0.6m-0.12m)+0.3m]×2×17=0.13合计：3.02次梁：b×h=200mm×400mm梁自重：(0.4m-0.12m)×25×0.2m=2.69抹灰层：10厚混合砂浆：[(0.4m-0.12m)×2+0.2m]×0.01m×17=0.13合计：1.28柱自重：柱尺寸：b×h=400mm×400mm柱自重：0.4m×0.4m×25=4抹灰层：10厚混合砂浆：0.01m×0.4m×0.4×17=0.03合计：4.03横墙自重：墙体：（3.0-0.6）×0.24×19=11.4粉刷墙面：（3.0m-0.5）×0.01×2×17=0.85合计：12.25纵墙自重：墙体：（3.0-0.4）×0.24×19=12.31水泥粉刷内墙面：（3.0-0.4）×0.01×17×2=0.98合计：13.23结构的线刚度计算在框架结构中，为了增大梁的有效翼缘，增大梁的有效刚度，减少框架的侧移，现浇楼板的楼可以作为梁的有效翼缘。为考虑这一有利的作用，在计算梁的截面惯性矩的时候，对于中框架取I=2I0（I0为梁的截面惯性矩）。梁采用C30混凝土，查表的，其弹性模量根据框架柱的刚度为1进行折算，则该框架的相对线刚度如下图3-1所示：图2.33框架的竖向向荷载计算3.1.梁的荷载计算3.1.1顶层屋板传递的荷载顶层板传至梁上的荷载为三角形和梯形荷载两种形式，首先把他们等效为均布荷载，经计算所有现浇板板块的长边与短边比均小于3.0，宜按双向板计算，从四角出45o平分线，区格板被分为四个小块，每小块荷载传给与之相邻的的梁，板传至梁上的三角形或梯形荷载等效为均布荷载。荷载的传递示意图如下：图3.1
