Re: 4" C Purlin Span
This is a little off topic from this thread, but I thought that someone might be able to help. I have a new home built with trusses and we are now getting drywall seam cracks in the ceiling. I've discovered that the trusses were not laterally braced according to specification. However, my question is that I saw some sections of bracing that consisted of very short purlins that only spanned the distance between each truss. They used a number of these short purlins and just staggered them down the entire row of where they thought the bracing should be. Is this method of using very short purlins acceptable? For instance, if the gap between the trusses was 16", then they used a number of 17" pulins and staggered them down the entire row.
