来自主题: CivilEngineering版 - 请教诸位一个问题
基本上hole都要比bolt要大一些,这个你看一下fabricator给你的图纸就知道了,不然
bolt根本装不上。有的时候还是slot hole。那个就大更多了。
也就是说,shear only的bolt connection本来就允许水平移动。上下两个bolt,可以
水平移动,自然就会产生rotation.
如果要设计moment connection,要把beam flange 给 connect到column上才能算是可
以传递moment的连接。

来自主题: CivilEngineering版 - 哎呀, 今天可能得罪了一个 SE
请他们做的consulting出的图,可能时间比较紧,有不少错误,有大有小。 一些
Notes 估计是从上个 project copied 过来的,有些是根本不搭嘎的,我给他们指出来
了一些比较明显搞笑的。虽然对方是 SE, 橡皮章也盖了,我还是想 red-line 他们的
drawings 再送出去. 说到其中 anchor bolt 和 base plate details, SE 的面子好像
就有点挂不住了。 我就给他们建议说,是不是应该定义 anchor bolts dimensions
from the column centerline instead of the outside flange of column 更好。 我
就说了,从你们的 base plate detail图 我都确定不了 base plate size 是多大如果
我不知 column size 的话,也不知道 anchor bolt 的位置,放 cast-in anchors 的
工人才不管你的column 有多大呢,只管确定在哪放下anchor bolts。呵呵,对方听起
来好像很不高兴,bla

来自主题: CivilEngineering版 - Bridge on steep grade
there is normally a beveled load plate welded to the bottom flange. the
bottom of the load plate is always level. under the load plate is the
bearing.
Some design guides (such as Penn DOT) says you need to consider it for
bridge on steep grade with INCLINED bearing.

早上好!
问题是这样:
在倾斜混凝土面上立wide flange column,一个选择是浇个小的混凝土Pad,得到水平
面,然后放柱、base plate,浇grout;另一个说法是,不浇混凝土pad,直接浇grout
pad就行了,5 Star Non-thrink Grout。
问问大家,不用混凝土Pad可以吗??在坡度上base plate以下需要厚度约为 1-6
inches。
多谢!!!

来自主题: CivilEngineering版 - two way slab concrete moment frame
分析时一般假设diaphragm as deep beam.作用就相当于I beam's web, carrying the
shear,而圈梁或者墙作为flange, resisting bending.如果没有圈梁,整个楼板要作为
平板来分析,主要考虑in-plane bending.
另外在开口处要验算collector and drag member,reentrance corner 要考虑应力集
中。

呢?

来自主题: ME版 - 请教一下简写的意思。
不懂装懂,误人子弟。哈哈
1。W14X120中的“W”指"wide-flange",即你说的“工字钢”标准构件。“14”指工字钢
的截面高度(你答对了),“120”指这种型号的工字钢轴向120 lbs/ft。
2。PL不知道。猜一下。是不是“CL”重叠写在一起?那么是"CenterLine"的意思,对于
对称结构而言。

前后端形状特殊(至少有个 flange ) 如果从铝管开始, 需要焊接, 又是一道工序,
不知道焊接的代工怎么样。 看淘宝上很多小厂做的东西基本都是只用车的

来自主题: Physics版 - Turbo pump能达到多高的真空度?
跟用的flange有关,跟backing pump也有关,当然pump大小,chamber size,
outgassing都有关系。
就pump本身来说,5*10_10 mbar没问题。不需要ion pump.

有关刚才的问题,我等不及了,就把那个飞碟形状的spacer给装到两个轴承之间了,猜
想可能这个飞碟在flange的基础上加固轮轴的定位,你可不要告诉我装错了,又得让我
没有工具的情况下一点一点撬轴承,赵老师说了,挺紧的。
另外,我刚才在车库里画了一圈,我已经不如我闺女了,这如何是好啊!

Very Good Reviews
The Lodge Logic Camp Dutch Oven can also double for a portable camp stove.
It is the pot that does it all. The flanged lid, purportedly designed by
Paul Revere, holds hot coals and inverts for use as a griddle. The integral
legs allow the oven to sit perfectly over hot coals

Out of factory, the C-Sonnar is always adjusted for minimal focus shift at f/2.8 at all taking distances. Except at close distances at f/1.5, this is the best compromise for 90% of our users. Depending on the tolerances of the rangefinder of your camera, you might recognize a small amount of focus shift at f/1.5 and closer distances.

来自主题: _FilmPhotography版 - 刚拆了kiev 4 玩
rangefinder 不准,
就按kiev survival site 上,
先试简单的办法, 不管用,
然后就先拆film plane casting,
然后top casting
然后shutter assembly,
lens helical
lens helical 下来以后, rangefinder 跟lens 就没有couple 了,
找infinity 一对,再把helical 转到infinity, 插回到mount 里,rangefinder
infinity
就好了, 拧死螺丝。然后对0.9米,perfect. 这就完事了。
然后一一装回去-----中间还给各个部分都上了些white lithium grease,
后来发现其实要卸lens helical 很容易, 把面板去掉,然后直接卸掉flange plate
的4个螺钉就可以了。shutter assembly 和top casting 根本不用动。
kiev4 不爽的是, shutter assembly 出来一根flash sync 电线,焊在PC sync
socket 上,
要卸shutter 的话

不过他这里要用示波器,没有,但有个更好的办法,
把他那个三极管信号出口结到laptop 声卡line in , 用recorder 录波形,然后用软件
展开
看波形,现在声卡分辨率很高,44kHz, 采样率足够测1/1000 秒的快门了。
今天把zorki 彻底拆开了,再装回去必须得测快门了,还要测flange distance. 顺便
换个新的shutter curtain
