6、大学合编现浇钢筋混凝土单向板肋梁楼盖设计指导书一、 平面结构布置：柱网及梁格布置应根据建筑物使用要求确定，因本厂房在使用上无特殊要求，故结构布置应满足实用经济的原则，并注意以下问题。1、柱网布置可为正方形或长方形。2、板跨一般为1.72.7m，次梁跨度一般是4.06.0m，主梁跨度则为5.08.0m，同时宜为板跨的3倍（二道次梁）。3、对于板、次梁和主梁，实际上不宜得到完全相同的计算跨度，故可将中间各跨布置成等跨，而两边跨可布置得稍小些，但跨差不得超过10%。二、板的设计（按塑性内力重分布计算）：1、板、次梁、主梁的截面尺寸确定。板厚 ，（当时，满足刚度要求，可不验算挠度）。次梁 ， 。主梁
7、， 。2、板的计算简图：板为多跨连续板，对于跨数超过五跨的等截面连续板，其各跨受荷相同，且跨差不超过10%时，均可按五跨等跨度连续板计算。 当按塑性内力重分布计算时，其计算跨度： 中跨： 边跨： . ()3、荷载计算： 取1m宽板带计算： 面层 水磨石每平方米重1 = 板自重 板厚1 = 平顶粉刷 每平方米重1 = 恒载： 活载：标准值1 设计值总值： = 4、内力计算：用塑性内力重分布理论计算，则有系数如下：则5、配筋计算：根据各跨跨中及支座弯矩可列表计算如下：截面1B2CM（） ()选 钢 筋实 际 配 筋位于次梁内跨上的板带，其内区格四周与梁整体连接，故其中间跨的跨中截面（、）和中间支座
8、（）计算弯矩可以减少20%，其他截面则不予以减少。为了便于施工，在同一板中，钢筋直径的种类不宜超过两种，并注意相邻两跨跨中及支座钢筋宜取相同的间距或整数倍（弯起式配筋）6、确定各种构造钢筋：包括分布筋、嵌入墙内的板面附加钢筋，垂直于主梁的板面附加钢筋。7、绘制板的配筋示意图：可用弯起式或分离式配筋。三、次梁设计（按塑性内力重分布计算）：1、确定计算跨度及计算简图。当按塑性内力重分布计算时，其计算跨度： 中跨： 边跨： ()当跨差不超过10%时，按等跨连续梁计算。2、荷载计算： 由板传来： 板恒载次梁间距 = 次梁肋自重： 钢筋混凝土容重 = 次梁粉刷重 粉刷层每平米重 = 恒载： 活载：活载标
9、准值次梁间距 设计值总值： = 3、内力计算： 值： 值：其中： 4、正截面强度计算：1）、次梁跨中按T形截面计算，T形截面的翼缘宽度按且考虑。支座截面按矩形截面计算。所以确定 。并判断是第几类T形截面。2）、钢筋截面计算如下：截 面1B2CM（）（） ()选 择 钢 筋实 际 配 筋截 面ACV（） (=)箍筋肢数、直径实配箍筋5、根据计算结果和构造要求，绘制次梁配筋示意图。四、主梁设计（内力按弹性理论计算）：1、计算简图：柱截面350350，由于钢筋混凝土主梁抗弯刚度较钢筋混凝土柱大的多，故可将主梁视作铰支于钢筋混凝土柱的连续梁进行计算。主梁端部支承于砖壁柱上，其支承长度a=370。则主梁
10、计算跨度： 中跨： （支座中心线之距） 边跨： 2、荷载计算：为简化计算，主梁自重亦按集中荷载考虑。 次梁传来的荷载： 次梁恒载主梁间距 = 主梁自重： 次梁间距 = 主梁粉刷重： 次梁间距每平米粉刷层重 = 恒载： 则 活载：次梁活载主梁间距 1)、其中，可由书中表查取，L计算跨度，对于B支座，计算跨度可取相邻两跨的平均值。2）、其中，可由书中表查取，3、内力计算：主梁弯矩计算项 次荷载简图 ()组合项次组合值()组合项次组合值由此可作出下列几种情况下的内力图：将以上各图绘于同一坐标系上，取其外包线，则为弯矩包络图。主梁剪力计算项 次荷载简图 ()组合项次组合值()组合项次组合值同样可绘出剪
11、力包络图。4、主梁正截面和斜截面承载力计算：正截面配筋计算截 面1 B2M ()选择钢筋实际钢筋注意：主梁跨中截面按T形截面计算，其翼缘宽度按如下计算：且，并判断是第几类T形截面。斜截面配筋计算截面AV（kN）箍筋直径、肢数弯起钢筋弯起钢筋面积实配箍筋5、主梁吊筋计算：由次梁传于主梁的集中荷载 F=G+Q则吊筋面积 所以选吊筋为： 面积：6、根据计算结果及构造要求绘制主梁配筋示意图。7、材料图及纵筋的弯起和切断。1）、按比例绘出主梁的弯矩包络图2）、按同样比例绘出主梁纵向配筋图，并满足以下构造要求： 弯起筋应在被充分利用的截面以外距离的截面处弯起（下弯点），上弯点距支座边缘距离为50mm。 切
12、断钢筋应在“理论断点”以外，当时，从该钢筋充分利用截面伸出的长度；当时，从该钢筋充分利用截面伸出的长度 纵筋伸入支座大于等于两根，且面积不得少于跨中钢筋面积的50%，并且伸入支座要有一定的锚固长度。五、有关制图的一些说明1、图纸： 采用2#图纸，2张2、图标：1、字体及图线：图纸上所有字体一律采用仿宋字，所有图线、图例及尺寸标注均须符合制图标准。2、钢筋明细表：构件名称编号简图（mm）直径长度（mm）数量总长（m）板次梁主梁（1） 对有弯钩的钢筋，在计算长度时，应加上弯钩长度，每两个半圆弯钩的长度为： 钢筋直径（mm）6810121416182022252832每两个半圆弯钩长度（mm）801
