Vertical forces include the weight of the home s construction components the occupants and exterior loads such as the added weight of snow.
Snow load bearing roof modular classroom.
Roof loads are a downward vertical force on the home.
Used but they typically defined the load cases or combination stress or strength limits and deflection limits.
Load bearing modular home walls include the framing exterior sheathing and drywall.
When we design homes in the mountains we pay careful attention to all the details of the building envelope to insure that the finished product will perform.
Load bearing walls in a modular home support the structure from both vertical and horizontal forces.
The ground snow load values are provided by a map created by the national weather service.
A mountain home should to be able to withstand all that nature throws at it and provide its inhabitants with a warm dry sanctuary from the elements.
D dead load l live load l r live roof load w wind load s snow load e earthquake load r rainwater load or ice water load.
Again snow loads are their own load specification because of the nature of precipitation.
Non load bearing modules.
Roof load live load design is affected by the shape of the roof whether it is flat curved or pitched.
They are used as toilet bathroom units plant rooms or other serviced units and are supported directly on a floor or by a separate structure.
The building code first identifies the ground snow load which helps to calculate the uniform design snow load on the building s roof.
Created by wind pressures.
However a south roof load zone home cannot be installed in either a middle or north roof load zone.
In areas of the state outside of certified city county and town jurisdictions the design snow load shall be based on the ground snow loads developed in snow loads for structural design in montana civil engineering department montana state university 2004 revised edition.
Load types loads used in design load equations are given letters by type.
Snow loads shall be determined by the building official.
Non load bearing modules are of similar form to fully modular units but are not designed to resist external loads other than their own weight and the forces during lifting.
It differs in that it will affect different portions of the building not limited to only the roof.
The roof sheathing supports gravity loads such as the roof live load snow load and vertical uplift loads.
These numbers represent the peak snow load that has a 50 yearly mean re occurrence interval of a 2 probability of.
Also the roof sheathing working in conjunction with the roof framing must function as a diaphragm to transfer lateral loads to the building s shear walls.
How much snow a roof can hold depends on the type of snow roofline and material among other considerations.
Snow and the mountain environment are tough on everything and your home is no exception.
These questions aren t quite so easy to answer because there are several variables.
