Purlin and girt system used in light steel buildings with gabled frames are described. In such buildings, roof and wall panel are always made with profiled sheet for the sake of cost saving and convenience in construction. Purlin and girt are always made with cold-formed channels and Z-shaped sections. In the light of related regulations in Technical Specification for steel structure of One-storey Light-weight Buildings with Gabled Frames( CECS102:98),author gives some explanations on layout, calculation and construction of cold-formed pulins and girts.
Keywords: gabled frame; light-weight building; steel structure; purlin girt
