In spite of spectacular development of reticulated shells, at least one problem has not yet
been solved satisfactorily and that is the problem of buckling. The instability of isolated …

Most existing studies on single-layer spatial structures with semi-rigid joints were focused on
spherical domes. The present paper analyzed the squared plan-form single-layer structures …

Socket joints and bolt-ball joints are typical semi-rigid joint systems widely used in spatial
structures. In this paper, tests on fifteen joints are carried out to study their mechanical …

Recent challenge for large-span single-layer reticulated structures is the development of a
new joint that can provide these structures with adequate stiffness while satisfying various …

Based on the bending stiffness of socket joints obtained through experiments, the finite
element models of single-layer elliptical paraboloid latticed shells with the semi-rigid socket …

Socket joint systems are typical semi-rigid joints used in space structures. This paper
presents numerical analyses of semi-rigid joint systems in which the bolts are pretensioned …

Both experimental study and numerical simulation were done to establish the bending
stiffness curves of bolt-ball joints. Using nonlinear beam element with end spring elements …

Abstract Single-Layer ORTZ (SLO) joint, as a kind of assembled joint, has been widely
adopted in single-layer latticed shells. However, previous research on this subject has …

Current research on aluminum alloy gusset joints has neglected the influences of the angle
between members and the curvature of the joint plate on joint performance. This study …

In a space structure, each connection can be subjected to different ratios of axial force to
bending moment. In this paper, a test procedure was presented that enables realistic testing …
