柱下条基设计(倒梁法)

计算弯矩,根据弯矩配置横向钢筋(横向钢筋采用16,).翼板的高度如计算简图所示,取1.0m宽度翼板作为计算单元,剪力设计值斜截面受剪承载力,满足要求。横向钢筋计算弯矩设计值;配筋计算:①截面抵抗矩系数②相对受压区高度;③内力矩的力臂系数④钢筋面积实配16@110,分布筋。六、沉降计算土层分层情况如下图:沉降计算采用荷载准永久组合,用角点法计算区域划分如下:例如:对于E点有地基变形计算深度算至强化闪长岩则,按GB50007-2002规定时且应满足沉降计算①E点:对;;001.178912.31581.00000.79307.812.85070.80.42111.178912.31580.99120.89081011.25971.80.94741.178912.31580.93542.207615.518.00266.73.52631.178912.31580.58080.2719103.43687.94.15791.178912.31580.52700.1156300.48718.54.47371.178912.31580.5034计算沉降经验系数首先计算变形计算深度范围内压缩模量的当量值据GB50007-2002表5.3.5,得所以边柱E点桩基础最终沉降量计算,满足GB5007-2002公式5.3.6要求。②D点:对;;004.96848.52631.00000.79427.812.87010.80.42114.96848.52630.99280.91071011.51121.80.94744.96848.52630.94722.593815.521.15206.73.52634.96848.52630.64160.3654104.61877.94.15794.96848.52630.59040.1570300.66158.54.47374.96848.52630.5674
