Ensuring Farm Building Strength at Critical Connections

Many modern farm buildings built with wooden framing are covered by a skin (or cladding) of ribbed metal sheeting. The combined strength of the framing and metal skin contributes to the economy of this type of building. Some primary structural members, such as wood trusses or laminated wood posts, are pre-fabricated. The majority of the connections between primary structural members, secondary structural members, and the building skin are made in the field, but are critical to the strength of the assembled building. Attention to these connections in design, construction, and maintenance will enhance building strength and longevity.

Concrete Inspection in Swine Buildings

Concrete is a significant financial cost in every modern swine building. The concrete pit, foundation, columns, beams, and slats are structural parts that should last 25-100 years, but if structural failures occur, they can be catastrophic to livestock and their caretakers. This publication discusses inspection and maintenance for the major components of a swine building, including visual references.

Installation and Maintenance of Wood Roof Trusses in Farm Buildings

Many modern farm buildings use wood trusses with metal connector plates (also known as truss plates) for their roof framing. These trusses are cost-efficient structural members if properly installed and maintained. Protection of trusses from damage and deterioration is critical to preserving their strength and life expectancy.

Gable End Attic Air Intakes for Swine Building Ventilation

Fresh air intake and distribution in a swine ventilation system is critical to providing a good environment for animals, but can have a negative impact on building longevity with certain designs. Air generally will flow into the attic to supply fresh air to the production room ceiling air inlets. A typical design brings air into the attic through soffit intakes at the eave. However, this design can negatively impact the building by contributing to corrosion and deterioration of metal.
