真不知道。

我对加拿大民用建筑是完全外行。以我结构工程师的标准看，加拿大的所有house地下室都完全不合格，就那么稀稀拉拉几根钢筋，底板还是薄薄的素混凝土，这怎么行？

但人家这么干上百年了，也没啥问题。

所以我对民用建筑只敢提问题，不敢下结论。

或许因为大部分是木结构，自重轻。

两码事。

因为是acreage，所以要自己修private lane。这是在Cat Loader里面照到。

Packer和2个track hoe（挖掘机），基本上把我们公司油井上用来维护的设备都拉来了。

有finishing 木工课的college 或者大学的图书馆去问一下，他们可能有参考书类的building code ，不能外借，但允许复印几页自用。或者有认识的教课老师去请教，他们会有书。

从RM那里拿到了frost line的数据了- 4 feet

那你给点数据上的意见吧。

building code is only used as minimal requirement. meet minimal requirement doesn't necessarily mean good quality. how many rebar depends on the lateral pressure of soil(geotechnical investigation). Normally, it is not worthwhile to do geotechnical investigation at all for single family house because the cost associate with it. Just talk with your contractor and ask for more rebars, it will cost only a few hundred dollars. steel rebar sale at around $2000 per ton or less . I am in structural(not license yet) but not in building.

24X18是mini，我这里用16X16，应该可以了吧？16X12可以做ternado cage了吧？

apart from rebar, proper back fill material, floor drainage system, weeping tile and grading is same important. because soil condition in Saskatchewan is not good, the foundation will heave up and sink down regularly depend on the moisture level and ground water level. concrete is brittle and weak in case of it is in tension. actually, when calculate its strength we take it as zero if it is in tension. that's why rebar is very important. because expansive soil in saskachewan, foundation wall sustain substantial lateral pressure, which in turn cause huge bending moment and cause crack on foundation wall. believe me the force of this lateral pressure is much much more compare with the tornado you talking about. with enough rebar, even the wall still will crack but it will hold the wall together, so only hairline crack will be on the foundation wall. With waterproofing film on the outside and foundation draining system, all these will prevent moisture get into basement.

是啊。不论怎么加强，concrete都会crack的。关键就是减少crack之后的移动。我让他们给我打双层rebar。

if double layer, that's much better. proper curing of concrete is also very important. normally 30Mpa concrete will be used for foundation wall. you need make sure concrete keep moisturized for at least 7 days. study show that if not moisturized properly concrete can only reach 40% of its design strength. after 7 days only 80 percent it strength achieved. In design, we normally use its 28 days strength, that's called design strength. during curing, the cement will absorb a lot of water. proper curing will also reduce shrink crack.

Footing已经做好了，怎么修改竖向钢筋？Hilti anchor?

钢筋不锚入footing，相当于没有钢筋。

How to keep concrete moisturized for 7 days ?
