| Abstract: | According to the mechanical traits of the continuous rigid frame,the width of the double thin-wall pier(b)in flat direction is deduced to satisfy the flexibility;the spacing of the double thin-wall pier(H)derived from unbalanced moment in construction is deduced.The simple and creditable formulas and the illustrations can be taken as reference in dimension designs. |
