If you are keen to building a cattle shade structure, then you should also be aware of the different things that may affect their durability and performance. Outlined below are some of the most common factors that can have a negative impact on the longevity and proper function of many cattle shade structures.
Wind load refers to the stress that the wind can effect on cattle shade structures and many other agricultural or industrial structure that makes use of a tensioned shade. Moderate to strong winds can blow through the shade structure and as it does it can cause some rippling effect or waves that cause the fabric to flap or billow. During this process, the wind forces the fabric material to endure unbalanced forces that may cause the premature failure of the shade fabric and the other components of cattle shade structures. The best way to deal with this issue is to ensure that the fabric is tensioned well into the post.
Horizontal winds, or those that blow in an upward direction, can also have an effect on the shade fabric, or what is sometimes referred to as ‘lift’ and causes the same damage to the shade fabric as those mentioned earlier. To keep this from happening, the fabric of the cattle shade structures should be properly angled to avoid ripping and enduring any damage.
There is also this thing called the dead load, which is basically the weight of the structure and the effect of gravity on it. In this case, the whole weight of the shade fabric is borne by the posts that hold it, or any other structure that supports it. In some of the cattle shade structures, the posts are installed at a certain angle as this is seen to help provide tension, though care must be taken that the posts are installed in the right angles or else it may have negative implications. Along this line, there are shade structures that make use of metal clad frames as these are seen to be more durable and resilient than mere shade cloths. However, they also tend to weigh more, thereby their dead load puts more stress on the supporting structures than the shade cloth alone. Still, the dead load of plain shade cloth should not be underestimated since they are still quite heavy by themselves.
