While the perception of floor vibrations is subjective from one person to the next, overall floor systems which exhibit lower deflections and less acceleration from vibration sources tend to be perceived better than other designs. To accomplish this, the designer may elect to do one or a combination of things, covered in this report.
Many factors go into classifying buildings. Each type will have different allowable height, allowable number of stories and allowable area limitations based on the classification. This report will focus on Type III-A building construction using fire retardant treated wood (FRTW).
Code compliant use of Metal Plate Connected Wood Trusses (MPCWT) to support brick veneer can be accomplished by both individual designs and by adhering to the recommendations that follow within this report. This discussion focuses on a common use of MPCWT’s; the gable end at the transition from a wider section of a building to a narrower section.
There are circumstances when the deflection requirements for a specific structure that utilizes floor trusses as structural members are questioned. The current residential and commercial building codes provide minimum design requirements for loads and for deflection of structural floor members, which also apply to floor trusses. The building designer may specify more stringent requirements. This research report will focus on manufacturer or trade association deflection requirements for a number of floor topping/covering related products
The capacity of a ribbon board and its system through the composite of the ribbon board, floor sheathing and bottom plate of the wall has not been ascertained. In order to provide better guidance, a series of tests were conducted in order to determine the capacity of the ribbon board system.
