From Concept to Collapse
The development of new products is essential for the continued progress of the building industry. New products can improve the performance and efficiency of building systems; however, they must as a minimum maintain the same level of public safety provided by proven existing products. This paper presents a case study of a new cold-formed steel joist roof framing system/product. The manufacturer designed and manufactured the product, taking it from the concept stage to implementation as a product sold for use in building structures. One of the buildings with this new roof framing system experienced a roof collapse during a rainstorm. Investigation of the collapse led to the discovery of design errors of the joist product and defects in its fabrication, leading to questions regarding the safety of this product and its suitability for use in a roof system. This case study also highlights the role of the design professional with regards to the selection and verification of new building systems and products.
