You can order up to 5 thumb bands in three sizes that say "TXTING KLLS" on
them. They're completely free, and shipping is actually pretty fast. I got
mine after a week, and it was actually shipped from allstate. I don't
think there's anything preventing multiple orders, but I didn't try either.
The order form is here:

and here's the corresponding facebook page where I found out about it:

不想和别人争论,只想问问lilyKang,您现在遇到了什么样的困难吗?
我是一名医生,我知道临终病人在抢救的时候,无论直系家属等候在ICU/抢救室外面
,或者陪伴着病人送他最后一程,心中是多么的悲痛欲绝,更清楚在病人去世后,家属
强忍着悲痛该面对多少繁忙的手续和事情。可是,即使在这样悲痛的心情下,和繁忙的
背景下,您依然来到网上更新了您爱人最后的一段时光和他对生的留恋。我不得不承认
,您是我见过的最为坚强的女性!
但是,为何您在公开捐款信息以后,除了看到一次更新以外,就从此消声匿迹了呢?是
忙得再也不能上网了吗?您本可以继续象从前那样,忙里抽闲,在这里更新您的状况,
诉说您的情怀,就象您从前一直做的那样。现在网上,除了您募捐之前写的那些文字,
还有捐款信息,没有您的支言片语,留下的却是围绕您的无穷争议,我真为此而感到心
痛!
我看到那么多的质疑和责问,说您富有,说您虚伪,说您恋财,说您懒... 阅读全帖 |

Z****g 发帖数: 13731 | 3 There is live load reduction for foundation. Live Load Element Factor Kll=1.
0, foundation is also considered an element. |

Z****g 发帖数: 13731 | 4 use the tributary area for the mat (40,000 sq.ft.) and the formula in ASCE
or
IBC with Kll=1.0, to calculate the reaction from the oil. Accordingly, the
force from column will use this reduction factor too (not the factor with
400 sq.ft).
This is my interpretation. |

r*********5 发帖数: 61 | 5 这道题是NCEES网上的PE Structural Sample Questions 中的一道题。给了恒荷和未折
减活荷,求A点反力. 题目和答案在二楼。我的问题有两个:1,对
于AB段live load 125 psf,根据ASCE 4.7.2, Kll是2,tributary area At是24X10,
二者乘积大于400 sq ft,则此段活荷需要折减。 2,求A点的service load,刚才看了
ACI 318,chapter 2中对load, service 的解释是"without load factors",那这么说
本题的service load 就不用factored,即答案不乘strength design或allowable
stress design的分项系数。
请大家帮我看看我想得对不对,要是有错误,请大家帮忙指正,谢谢! |

r*********5 发帖数: 61 | 6 那这个呢?这个需不需要折减? 如果double-tee 可以按梁考虑,那Kll就是2,
tributary area At=60X15,二者乘积大于400,且不在4.8.2~4.8.5的限制之内。 |

For example, Al KLL peaks, where did the emitted electron from K shell go? |
