二、柱下单独基础柱子承重的房屋,其基础为柱下单独基础。钢筋混凝土柱子下面多用钢筋混凝土单独基础。由柱传给单独基础顶面的荷重有轴心力N、弯矩M和水平剪力Q。一般对埋置深度不大的基础,Q的影响较小,可忽略不计。只有轴心作用的垂直力N,叫轴心受压基础。除了N,还有M作用的基础,叫偏心受压基础。两者计算稍有不同,分别介绍(只介
Second, under the column alone base pillar load-bearing house, its foundation is a separate base under the column. Below reinforced concrete pillars, reinforced concrete alone is used. The load transmitted from the column to the individual base top surface has axial force N, bending moment M and horizontal shearing force Q. Generally, the influence of Q on the foundation with a small depth of embedment is negligible. Only the axial force acting on the axis A is called the basis of the axial compression. In addition to N, there is a basis for the role of M, called eccentric compression foundation. The calculations of the two are slightly different.
