Hi everyone,<br>I have a proposal for Sven, about the project of his house. If you make the roof more steep in the central part, and leave the slope like this at the end, it will reduce the hevy snow loads. The snow from the steeper part will push the snow from the lower roof, and <br>
in snowy days it will be self-regulating.<br>I know that this project is already approved from the local authoroties, but as you know "The problem is solution" <br>May be something like this, the attached pdf (there are lot of oppоrtunities to assimilate this space).<br>
Hope to be in help, just sharing ideas.<br>Wish you luck.<br>Niki<br><br><div class="gmail_quote">On Mon, Feb 28, 2011 at 11:13 AM, paul <span dir="ltr"><<a href="mailto:paul@naturalbuilding...">paul@naturalbuilding.fi</a>></span> wrote:<br>

These are very interesting points and a great subject for us to talk about, but I still am awash with lots of OPINIONS and am really looking for more FACTS.<br>
<br>
In simple questions<br>
<br>
What is the background knowledge for people's opinion about load-bearing SB-structures;<br>
a) We have seen some calculations done for a load-bearing structures, but with very different results, It is similar questions asked but with varying answers, almost each test result you read, reads differently? Why? I agree with Max about bale sizes etc.. but is that really the answer?<br>
b) what are these calculations based on? ( some are on tests, yes, but is seems some are on common sense? Is this good enough for the authorities in your country?...)<br>
c) have these calculations been approved by building authorities? This is a main point! Can anyone show me where an authority has approved these tests (loadbearing and creep tests for anyone who hasn't been following this topic so far) in Europe, especially with heavy snow loads??<br>
<br>
Thanks again in advance for these discussions and your answers.<br>
