Building Ends on an MSS Structure

One of the beauties of a Multi Shelter is the flexibility of the ends. By building the ends according to your needs your new building can and will truly prove useful.

It is important to remember that you need to be very careful when you have one end closed and the other end open.

When one end is closed you could potentially create a “parachute effect” (trapping air, creating lift) and put a lot of added stress on your building and especially the cover. Call us to discuss ways of minimizing this if your circumstance really would require one end open and one end closed.

When planning ends, it is important to have sufficient vertical framing to support wind load, doors, fans, etc. The spacing between the vertical framing will be determined by the amount of opening space required for the doors, etc.

It is important to remember that where ever possible, framing needs to go from top to bottom. In the event of large openings, the related framing will need to be doubled or tripled.

It is also important to remember that when you are covering your end with tarp, the top end of the cover is sandwiched between the wirelock channel and the hoop.

When you are covering with plastic, you will be fastening the top end inside the channel with the roof cover even if your roof is a double layer.

Roll Up Side Wall Considerations

Ventilation can either be done passively through openings or mechanically with fans. Roll up sides are an economical way of getting lots of air movement since no electricity is required. Roll up sides become even more effective when used on longer buildings. Roll up sidewalls are often used in combination with a small exhaust fan for early and late season ventilation when opening the sides is not practical.

If a structure is very exposed, it is best not to open more then 3’ in height due to potential of wind damage. If a structure is extremely sheltered, it is best to go even up to 6’ to create maximum opening. Roll up sidewalls are most effective when used in combination with peak end wall vents to create a “chimney effect” to draw warm air out of the building, especially when it is very calm. These vents are effective for air movement when outside temperature does not allow opening of the sides.

When a structure has a low profile, you will need to be careful during rainy periods due to moisture getting into the structure area. High profile structures (with straighter walls) usually work better with roll up sidewalls. When preventing a floor draft is an issue, the roll up mechanism can be raised and then the structure is lined with a skirt for the bottom 2’-3’. When using this method of ventilation, it should always be done on both sides. An effective use of this method includes opening the “downwind side totally and the opposite side on marginally.

Structures on Blocks or Shipping Containers

Storage containers and over sized concrete blocks are the economical solution for needing to elevate structures to create more storage capacity.

One consideration is when the product being stored does not lend itself to stacking, such as salt, sand or soil, there is the added dimension of outward push on the wall. Not only does the pile push outwardly, but an operator scooping the product will create even greater push.

Storage containers and over sized concrete blocks are the economical solution for such a situation. The weight and the stability which both the containers and blocks give, eliminates the need to anchor into the ground.

Containers are often simply put on the ground.

When going more then two layers with the blocks, there should be a concrete pad or special preparation of the soil to provide stability.

When choosing this foundation method, it is important to consider how and where the shelter will shed water and snow.

The top of the wall or container must be sealed to the possibility of moisture going inside.

The other thing that must be given proper consideration is that the shelter is able to deal with the extra wind load created by elevating the shelter this much.

In most of these installations, the wind load on a building is at least double of what it would be if mounted on the ground.
