t ioox一ngJ一ehu条形基础(strap foundation)长度很大并与建筑物地面以上结构形状相适应的基础形式。按结构形式分为墙下条形基础、柱下条形基础和柱子交叉条形基础。条形基础的横截面一般呈倒T形。条形基础的底面宽度、基础高度和配筋按平面问题计算确定。 墙下条形蓬础承受较小荷载时用砖、石、混凝土建造,按刚性基础结构方法计算;承受较大荷载或地基承载力较小时,用钢筋混凝土建造,在轴向或单向偏心荷载作用下底板的弯曲可按扩展(板式)基础简化方法计算。 柱子条形基础单列柱下的条形基础(图1)用钢筋混凝土建造,适用于下述情况:(l)柱下承受较大的荷载或地基承载力较小时,采用独立基础会发生过大的沉降和差异沉降。(2)柱下靠近建筑物,独立基础平面尺寸受限制或基础间距较小。柱下条形基础的构造同倒置的钢筋混凝土T形梁相似,也可设计成梯形底面。柱下条形基础当梁高大于1/6柱距且柱荷载分布较均匀时可按刚性基础结构方法计算,如不满足上述条件可按弹性地基梁方法计算。口塞鳌瘾‘鑫基井袋 l选乙 fl一n 图1柱下条形墓础 1一柱,2一其板.3一肋梁 a一等截面的.b一柱位处加肢的 柱下交叉条形基础柱网下纵横二个方向的条形基础(图2)用钢筋混凝土建造,具有一定的空间刚度和适应地基软硬不均或框架结构中各柱荷载不等的情况。由于交叉条形基础能够增强基础的刚度和整体性,故有利于结构抗震。设计计算时,对基础交点上的柱荷载可按刚度分配或按变形协调原则沿两个方向分配,其内力分别按两个方向的弹性地基梁计算。碘 图2柱下交叉条形荃础 (朱正庭)
