1) tension members with large eccentricity
大偏心受拉构件
1.
On the normal section design of doubly reinforced flexural members,tension members with large eccentricity and compression members with large eccentricity,the balanced section is designed in general,of which the equifinal depth of compression zone equals to the balanced depth of compression zone.
钢筋混凝土基本构件设计中,有两个问题值得商榷:(1)双筋受弯构件、大偏心受拉构件以及大偏心受压构件的正截面设计问题中的常见做法是在基于截面等效受压区高度等于界限高度时截面纵筋总配筋量最少的认识下将截面设计成界限截面,但根据推导,界限截面并不是纵筋总配筋量最少的条件,而且设计成界限截面还会丧失截面的延性,降低构件的可靠度。

The section strength for the reinforced concrete eccentric tension members is analyzed based on the traditional “plane sections remain plane” assumption (the Bernoulli′s principle) and the Code of Design of Concrete Structures(GBJ10\|89) respectively.

补充资料：在AutoCAD中偏心圆锥与偏心圆台实体的画法
现在要画一个偏心圆锥,底面在WCS的XY平面上,圆心(0,0,0),半径100,顶点(300,0,400)在ZX平面上.
1)连接PA,PB. A(-100,0,0) B(100,0,0)
图1
在当前坐标下:
2)延长PA到C,使PA=CA;延长PB到D,使PB=DB;
3)连接CD;
4)以CD为直径画圆;
5)用XLINE命令中的二等分选项作角CPD的角平分线PO,交CD于O;
6)过O作CD的垂线,交圆于E,F;
图2
7)用三点UCS命令,取三点为:O,P,C;
8)过点O作PO的垂线GO,交PC于G;
图3
9)再次用三点UCS命令,取三点为O,F,G;
10)现在就可以画椭圆锥了!
cone-e-c-捕捉O点-捕捉F点-捕捉G点-a-捕捉P点;
图4
11)回到WCS,剖切椭圆锥
SL-选择椭圆锥-回车-XY-回车-捕捉P点.
12)删除辅助线条.
