Abstract
In order to clear constructional design of corner joint, it is necessary to further investi-gate mechanical property of corner joint in gabled frames. Through static test and finite element software analysis of comparing the panel zone with and without inclined stiffener. Some conclusions are given in the article. The load displacement curves show that the capacity of oblique nodes installed within stiffening rib components is enhanced i.e. 40% more than those without stiffening rib nodes. The results reveal that in the gabled frames, the corner node with the inclined stiffening rib can improve the bearing capacity of the specimens. When the extraterritorial flange is tension, the erection of the inclined stiffening rib can prevent structural failure and improve effectually the ductility of the structure.
Highlights
Gabled frame structure is the most widely used structure in single industrial house and single large-span civil building at home and abroad, and the function of corner joints in gabled frame is extremely important
The results reveal that in the gabled frames, the corner node with the inclined stiffening rib can improve the bearing capacity of the specimens
This says that setting the inclined stiffening rib in corner joint zone can improve the bearing capacity greatly
Summary
Gabled frame structure is the most widely used structure in single industrial house and single large-span civil building at home and abroad, and the function of corner joints in gabled frame is extremely important. The construction of corner joints is not uniform. According to the Technical Specification for Steed Structure of Light-weight Buildings with Gabled Frames (CECS102: 2002) in (7.2.10), when the shear stress in the joint zone below the design value of shear strength of steel, stiffening rib is not necessary. When stiffening rib is needed, a reasonable setting method is not explicitly given [1] [2]. It is necessary to further investigate mechanical property of corner. Through full-scale experiment, some useful conclusions are given, and it has guiding significance for practical engineering
