Abstract
The focus of this paper is to propose a design recommendation for side-plate thickness for apex joint. Nested box section has been used as main member (column and rafter) in the frame. The NTBB section is distinctive as it consists of two G-sections welded together along their edges. A notable feature of the NTBB is its potential for tapering, which leads to material savings. The paper presents a non-linear elastoplastic finite element (FE) model, along with an analysis of 112 distinct finite element models. In the subsequent parametric study, variations in side-plate thickness, pitch, and size were explored. Both gravitational loading (opening moments) and wind uplift (closing moments) were considered.
