It details design assumptions and load types, including dead loads, live loads, wind actions, guidance on other loads, and methods for computing wall and roof loads on floor trusses. The guide further covers performance factors, durability topics such as ventilation and corrosion protection, and extensive construction detailing across walls, beams, cantilevers, openings, stair and duct coordination, stability, bracing, and fixing at supports.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/pryda-specification-guide-for-floor-and-rafter-truss-systems-april-2012/651165/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/pryda-specification-guide-for-floor-and-rafter-truss-systems-april-2012/651165.png","ImageObject",300,407,{"name":42,"@type":43},"\tCallum ","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-29","2026-10-24",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What load types are addressed for Pryda floor truss design considerations?","Question",{"text":63,"@type":64},"The guide covers permanent actions (dead loads), imposed actions (live loads), and also includes guidance for computing wall and roof loads on floor trusses.
