我们曾审核了一些设计资料,发现不少农房的设计人员对钢筋混凝土柱设计时,往往不加区别,统统按照轴心受压构件进行计算。应该指出,在多数情况下,这是偏于不安全的。梁和柱混凝土一般是整体浇筑的,在垂直荷载作用下,在梁柱的交接处,由于梁存在负弯矩,对中柱来说,当节点两侧梁的负弯矩
We have reviewed some of the design information and found that many designers of farmhouses tend to make no difference in the design of reinforced concrete columns and calculate them all according to the axial compression members. It should be pointed out that in most cases, this is biased towards insecurity. Beam and column concrete is generally a whole pouring, under the vertical load, at the junction of the beam and column, due to the presence of negative bending moment beam, for the column, when the node on both sides of the negative bending moment
