Résumé :

This paper presents a numerical study of spatial steel structures covering the design of a hollow ball-tube bolted joint system (HB) and its application to a single-layer spherical reticulated dome of type Kiewit 6 (K6). First, a so-called hollow ball-tube bolted joint system (HB) has been designed, and its bending rigidity was determined. Based on the bending-rotation curves of the HB joint system obtained through numerical simulation, a finite element model of single-layer reticulated domes with HB joint system is developed using nonlinear beam element with end-spring elements in ANSYS software. Results are compared with the rigid dome, designed by the continuum method. The analysis has been conducted using key parameters such as loading system, ratio of rise to span with a constant span and fixed support condition around the edge.
