地下室结构弯矩表设计师参考必备

1、 工业建筑结构设计混凝土结构设计指南及规定 第七册 地下结构弯矩表 （共八册）中冶京诚工程技术有限公司 工业建筑院二五年七月适用条件电缆隧道、地下通廊、建筑物地下室、设备基础地下室、地下料仓等地下池类结构，侧壁及底板按强度及裂缝宽度控制的最大弯矩值。与水池结构不同，裂缝宽度计算系按混凝土结构设计规范（GB 50010-2002）第8.1.2条进行，最大裂缝宽度按0.2mm。 目录 1表格使用说明 2 2钢筋保护层厚度30mm的弯矩表 4 3钢筋保护层厚度40mm的弯矩表29 制表：覃嘉仕 审核：孙衍法 审定：李绪华表格应用说明1最大裂缝宽度按0.2mm。2侧壁受力筋砼保护层厚度按30mm，底板

2、受力筋砼保护层厚度按40mm。侧壁受力筋为内层钢筋时可近似按保护层厚度40mm查表。当侧壁或底板配置双排钢筋时(h800mm)，可按保护层厚度40mm查表，将强度和裂缝控制的弯矩值分别乘以0.95、0.90的折减系数。3砼强度等级按C25、C30两种。4强度控制的最大弯矩值与基本组合弯矩值对应，基本组合弯矩值由设计人根据结构型式及荷载种类，再考虑荷载分项系数进行计算。荷载分项系数如下： 水、土压力： 1.2 地面荷载： 1.4 车辆荷载： 1.45裂缝宽度控制的最大弯矩值与标准组合弯矩值（无地面荷载时）或准永久组合弯矩值（有地面荷载时）对应，车辆荷载不考虑。地面荷载准永久值系数按下列取值： 1

3、00 kPa 0.5 100 kPa 0.4地面荷载除通过土压力作用于侧壁外，也可能直接作用于地下室、地下隧道的顶板。6设计人计算出两种弯矩后，根据侧壁厚度或底板厚度按钢筋直径从小到大查出与之较接近的弯矩值（此弯矩值必须计算的弯矩值），从而确定配筋。注意核对配筋率，最好在0.3% 0.8%之间，否则应考虑调整厚度。当弯矩值最大部位（如侧壁根部）的厚度及配筋较适宜后，其余弯矩值较小部位应在满足弯矩值及最小配筋率前提下尽可能采用较小配筋，此时不必考虑较适宜的配筋率。7选择配筋时，应在满足强度和裂缝宽度要求及较适宜配筋率前提下，尽量选配较小直径钢筋。850、75属钢筋在水平或竖向转角处弯折形成的，此

4、时的配筋率可0.8%，非弯折区不得以此间距直接配筋。双排100、150的配筋可按50、75，保护层厚度40mm查表，但两种弯矩值需进行折减，见第2条。9表格中带有对角斜线的部分为不得采用的配筋，原因属下列其中的一种： 1）低于最小配筋率 2）超筋 3）钢筋净距不符合规范要求，即30 mm及1.5d10有关内力计算及构造要求同水池结构设计指南。钢筋保护层厚度30 mm按强度及裂缝宽度控制的最大弯矩值壁、底板厚度(mm)配筋(HRB335)强度控制的最大弯矩M(kN.m)裂缝控制的最大弯矩M(kN.m)配筋率(%)As/bh0直 径间 距C25C30C25C3025012200353523240.
