给你提顶了

i just see it,do you still need it?maybe i can try to help

帮你提顶了。

The input window consists of Configuration panel, Flange & Web panel,
输入窗口包括了构造菜单，翼缘腹板菜单，
Stiffeners panel, and Welds Panel. The user can enter the corresponding
加劲板菜单及引弧板菜单。用户在设计梁时在相应的菜单输入信息．
input for the design of plate girders in those panels. Span length, lateral

（参见5.11中梁的设计方法），
and distributed and concentrated loads are set in the configuration panel
及分布和集中荷载在构造菜单中输入．（图９.２９）
(Fig. 9.29). The loading on the girder may consist of a uniformly
主梁的荷载通常由
distributed load plus a specified number of concentrated loads. The
不均匀分布荷载与几个集中荷载组合而成。
concentrated loads are named alphabetically from left. Alphabets “A”
集中荷载从左到右依次按照字母表顺序命名。但字母“A”和“B”
and “B” are reserved for the left and right supports, respectively. The
仅分别限左端及右端支坐。
girder may have either full lateral support or
主梁要么侧向完全支固要么
intermediate lateral supports. Width, thickness, and steel type of flange
侧向间断支固． 腹板和翼缘板的板材厚度及种类
plates and thickness and steel type of the web plate are set in the flange
要填入腹板及翼缘板窗口。（9.30a）

开始设计主梁用板之前，用户仅需对腹板及翼缘用板进行具体说明。
to specify the steel types of flange and web plates only. The applet

displays the first design results as shown in Fig. 9.30b. Like other applets
本应用程序的第一部分计算结果如图9.30 b所示。
presented in the previous chapters, this applet requires minimum amount
如别的程序一样，本程序也只有设计参数输入达到最小值要求时才能运行。

尽管如此，用户仅通过改变一个或几个输入值就可以多次重复使用程序设计。
simply by changing only one or several of the input values. To design a

hybrid girder, the user needs to select the steel types of flange plates and
设计组合梁时，用户需谨慎选择腹板及翼缘的钢材。
